Novel Pharmaceutical Formulations FIELD OF THE INVENTION The present invention relates to an oral pharmaceutical formulation, suitably tablets, suitably capsules, comprising an active pharmaceutical ingredient (API) and at least on micelle or liposome or microemulsion forming agent, wherein the an active pharmaceutical ingredient is not 3'-[(2Z)-[1-(3,4-dimethylphenyl)-1,5- dihydro-3-methyl-5-oxo-4H-pyrazol-4-ylidene]hydrazino]-2'-hy droxy-[1,1'- biphenyl]-3-carboxylic acid (INN name eltrombopag) or a pharmaceutically acceptable salt thereof. Particularly the API is not eltrombopag monoethanolamine or eltrombopag bis-(monoethanolamine). BACKGROUND OF THE INVENTION As reported in Promacta drug label, an open-label, randomized-Sequence, crossover trial was conducted to assess the effect of food on the bioavailability of eltrombopag. A standard high-fat breakfast significantly decreased plasma eltrombopag AUC0-∞ by approximately 59% and Cmax by 65% and delayed Tmax by 1 hour. The calcium content of this meal may have also contributed to this decrease in exposure. In a second trial, administration of a single 25-mg dose of eltrombopag for oral suspension to adults with a high-calcium, moderate-fat, moderate-calorie meal reduced plasma eltrombopag AUC0-∞ by 75% (90% CI: 71%, 88%) and Cmax by 79% (90% CI: 76%, 82%). Administration of a single 25- mg dose of eltrombopag for oral suspension 2 hours after the high-calcium meal reduced plasma eltrombopag AUC0-∞ by 47% (90% CI: 40%, 53%) and Cmax by 48% (90% CI: 40%, 54%). Administration of a single 25-mg dose of eltrombopag for oral suspension 2 hours before the high-calcium meal reduced plasma eltrombopag AUC0-∞ by 20% (90% CI: 9%, 29%) and Cmax by 14% (90% CI: 2%, 25%). This is because eltrombopag chelates with coordinating metals, especially with calcium, and forms insoluble complex. As a result eltrombopag formulation has greatly reduced dissolution rate in the presence of calcium (example 8, WO/2008/136843). Hence eltrombopag has reduced bioavailability in the presence of food, especially calcium-rich food (negative food effect). Generally, negative food effect is associated with BCS Class III drugs (high solubility and poor permeability; Reference: https://cuvillier.de/de/shop/publications/6557). For such poorly permeable drugs, absorptive transporter effects predominate and in presence of food the transporters are inhibited leading to negative food effect. However eltrombopag is low soluble/medium to high permeable. The mechanism for the negative food effect is predominantly related to the property of the drug that is, its tendency to chelate with polyvalent cations. It should be noted that the drop in bioavailability is seen only when the meals are fortified with high levels of calcium while there is negligible drop with low levels of calcium (Daphne D. Williams et. al. Clinical Therapeutics/Volume 31, Number 4, 2009). Solubility enhancement with surfactant is generally used as means of mitigating positive food effect of poorly soluble drugs. For example the bioavailability of abiraterone increases with food. After a low fat meal, Cmax and AUC are elevated 7- and 5-fold compared with the fasted state, whereas after a high fat meal there is a 17- and 10- fold elevation. WO2013/164473 teaches to mitigate food effect by including in the abiraterone formulation one or more lipid excipients and “The majority of these lipid excipients also have surfactant characteristics and many function to improve both the solubility and permeability of abiraterone”. Surfactant does not seem to be an effective means to address negative food effect issue, especially when the food effect is not due to low solubility of the compound, rather due to the complexing property of the compound with polyvalent cations, especially calcium in the meal. Antibiotics like Tetracyclines have been well-known in literature for their interactions with Calcium and the reduction in bioavailability when co-administered with foods containing calcium. In its general statement concerning tetracyclines, the AHFS Drug Information notes that the absorption of tetracycline is reduced by 50% or more in the presence of food or milk, while the absorption of doxycycline may be reduced by up to 20% by food or milk. Meyer et al. examined the pharmacokinetics of doxycycline in nine healthy volunteers who received capsules containing 200 mg of doxycycline with 300 ml of milk or 300 ml of water. The authors of this study reported that simultaneous administration of milk diminished the peak plasma concentration of doxycycline by 24% and the absorption by 9%-35%. The authors concluded that, like other tetracyclines, doxycycline should not be administered together with milk. (Ref: Meyer, F.P., Specht, H., Quednow, B. et al. Influence of milk on the bioavailability of doxycycline — new aspects. Infection 17, 245–246 (1989). https://doi.org/10.1007/BF01639529). Similar to tetracyclines, Quinolone e.g, Norfloxacin, ciprofloxacin, enoxacin, lomefloxacin, also show interaction with antacids containing aluminium and magnesium ions and milk products within gut. A study in 7 healthy subjects found that 300 mL of milk or yoghurt reduced the peak plasma levels of a single 500-mg dose of ciprofloxacin by 36% and 47%, respectively, and reduced its AUC by 33% and 36%, respectively (Neuvonen PJ, Kivistö KT, Lehto P. Interference of dairy products with the absorption of ciprofloxacin. Clin Pharmacol Ther (1991) 50, 498– 50). In another study, 300 mL of milk reduced the AUC of ciprofloxacin 500 mg by about 30% (Hoogkamer JFW, Kleinbloesem CH. The effect of milk consumption on the pharmacokinetics of fleroxacin and ciprofloxacin in healthy volunteers. Drugs (1995) 49 (Suppl 2), 346–8) . Accordingly, the FDA labeling information states restriction on the consumption of antacids, metal cations two hour before or 6 hour after ciprofloxacin dosing (https://www.accessdata.fda.gov/drugsatfda_docs/label/2016/0 19537s086lbl.pdf).

DESCRIPTION OF THE INVENTION Surprisingly we have found that surfactant vitamin E TPGS can effectively mitigate the food effect on eltrombopag, i.e. mitigate the reduction of bioavailability in the presence of food, especially calcium rich food. We have found that vitamin E TPGS can effectively a) prevent eltrombopag from binding to polyvalent cations (e.g. calcium); b) prevent the formation of insoluble complex of eltrombopag and polyvalent cations (e.g. calcium); c) release soluble eltrombopag into the medium despite the presence of excessive amount of polyvalent cations (e.g. calcium), typically shown in an in vitro dissolution test; d) increase the solubilization of eltrombopag, typically shown in an in vitro dissolution test; e) prevent soluble eltrombopag from crashing out of the medium, typically despite the presence of excessive amount of polyvalent cations (e.g. calcium), typically shown in an in vitro dissolution test; and/or f) increase the permeation of eltrombopag through Flux in-vitro test PAMPA Any one of the above effects or any combination thereof can be generally called the anti-calcium effect in this application. While the above anti-calcium effect achieved with the invention was firstly demonstrated with eltrombopag, it is scientifically reasonable to expect that this finding is generally applicable to other APIs, having similar properties as eltrombopag (API of the Invention). Thus this invention would be useful, inter alia, in the field of pharmaceutical formulation, especially for APIs having food effect, especially when the food effect is likely caused by the presence of polyvalent metals, such as calcium in the meal. The present patent application carves out subject matter relating to eltrombopag, which was disclosed in the international patent application PCT/US2020/051593. Any mention of eltrombopag in the present patent application is for illustration purpose and any data relating to eltrombopag is to support the general inventive concept and to support the technical effects of the invention. One property is that the API of the Invention is capable of chelating with polyvalent metal cations and form an API-metal complex. Polyvalent metals include but not limited to aluminum, calcium, copper, cobalt, gold, iron, bismuth, magnesium, manganese selenium and zinc. API of the Invention is capable of chelating with at least one polyvalent metal. Suitably the polyvalent metal is common in diet, including dietary supplement, such as calcium, iron, magnesium, manganese, copper, selenium and zinc. Suitably API of the Invention is capable of chelating with calcium. One property of API is to have functional chemical groups in a configuration which results in formation of API-metal complex. Functional groups to which metal cation bind include but not limited to phenolic, ketone, catechol, carboxyl, amine, hydroxyimino and sulphydryl groups. The functional groups have electron pairs which interact with the metal ion to form complex. API-metal complexation can include one or more functional group of one or two or multiple API molecules. Generally, a stable API-metal binding results in formation of five or six membered ring structure. The term “API-metal complex” as used herein, is well understood by a skilled person in the field. Typically the binding affinity between the functional group and the metal is characterized by an association constant/formation constant/stability constant. It is an equilibrium constant and is a measure of strength of interaction between the API, i.e. ligand (L) and the metal ion (M). An API can form multiple complexes as ML, ML2, ML3 and likewise. Formation of each complex species is characterized by a constant also known as stepwise stability constant e.g. K1, K2, K3 and likewise. The overall complex formation constant K is equal to K1*K2*K3....likewise. As would be apparent to a skilled person the measurement of formation constant is tedious and is affected by multiple factors i.e. metal ion, ionic charge, ligand/ion concentration, pH and other ions e.g. H+ in the solution. Basis the measurement conditions the K value changes. Higher the value of stability constant, stronger is the complex. API that could form API-metal complex in the stomach, i.e. under acidic pH, e.g. pH ≤ 2, is particularly included as API of the present Invention. Alternatively, the protection of API under acidic condition could be extended to relatively basic conditions of the intestine, which is downstream to the stomach and is major site of drug absorption for most drugs. The formed API-metal complex can either have reduced solubility/dissolution or reduced permeability or both, compared to the API alone, in the physiological conditions of absorption. Alternatively, the API-metal complex can have high solubility but reduced permeability in the physiological conditions of absorption. In general due to the API-metal chelating the bioavailability is reduced. Alternatively a medicament comprising API of the invention has negative food effect when taken together with food, especially calcium rich food, or vitamin/mineral supplement. One additional property is that the API of the Invention has low solubility. The term “low solubility”, as used herein and hereunder, is understood as below 100mg/ml, even more below 50mg/ml, even more below 25mg/ml, even more below 10mg/ml, even more below 2mg/ml in an aqueous medium. Suitably the API has a solubility at least above 0.05mg/ml. Suitably the solubility is tested under neutral pH condition, typically in aqueous medium. One additional or alternative property is that the API has low solubility tested in acidic pH condition, typically in aqueous medium. One additional or alternative property is that the API has high permeability. One additional or alternative property is that the API is a class I, II, III or IV compound. Typically the API of the Invention is a class II compound or a class IV compound. The API could belong to BCS class I, II, III or IV basis the API solubility and permeability. BCS classes of the API’s can be defined as, Class I: High Solubility – High Permeability Class II: Low Solubility – High Permeability Class III: High Solubility – Low Permeability Class IV: Low Solubility – Low Permeability Reference (references: Waiver of In Vivo Bioavailability and Bioequivalence Studies for Immediate-Release Solid Oral Dosage Forms Based on a Biopharmaceutics Classification System Guidance for Industry (U.S. Department of Health and Human Services Food and Drug Administration Center for Drug Evaluation and Research (CDER)), December 2017, Biopharmaceutics) Here, a drug substance is considered highly soluble when the highest strength is soluble in 250 mL or less of aqueous media within the pH range of 1 - 6.8 at 37 ± 1°C. High permeability refers to a condition when the systemic BA or the extent of absorption in humans is determined to be 85 percent or more of an administered dose based on a mass balance determination (along with evidence showing stability of the drug in the GI tract) or in comparison to an intravenous reference dose. Reference for the image - The AAPS Journal, Vol.11, No.4, December 2009 (# 2009) DOI: 10.1208/s12248-009-9144-x One additional or alternative property is that API could have Dose number of ≥1. Where the dose number is the ratio of the Dose to the amount of the compound that can be dissolved in the dose Volume (default is 250 mL in human) of fluid at the pH of lowest solubility between pH 1.0 and pH 6.8. If the Dose Number is equal to or greater than 1.0 it means dose is not completely soluble, and if the value is below 1.0 it indicates dose is completely soluble. Alternatively, the API could have Dose number below 1. APIs have the chelating property alone or in combination with any one or more of the other properties are envisaged to benefit from the inclusion of Vitamin E TPGS to overcome the food effect due to the presence of polyvalent metal cations, especially calcium in the meal. Suitably API of the Invention includes but not limited to the compounds listed in Table 1. Thus the present invention relates to a pharmaceutical composition (pharmaceutical composition of the invention), preferably in an oral dosage form, comprising an API (API of the invention) or a pharmaceutically acceptable salt thereof and Vitamin E TPGS. Vitamin E TPGS is chemically D-alpha-tocopheryl polyethylene glycol 1000 succinate. It is an amphipathic and hydrophilic surface active agent. It typically has a low critical micelle concentration about 0.02% w/w. It is traditionally being used as emulsifier, solubilizer, absorption enhancer and vehicle for lipid based drug delivery formulations. [Vitamin E TPGS as a molecular biomaterial for drug delivery https://doi.org/10.1016/j.biomaterials.2012.03.046]. Compound is in the free form (acidic or basic), solvate form or in a pharmaceutically acceptable salt form. The term “weight of the API” as used in the context of the present invention refers to the weight of the free form, unless specified otherwise. In one embodiment the pharmaceutical composition of the invention comprises an API of the Invention, solvate, or a pharmaceutically acceptable salt thereof and vitamin E TPGS, wherein the weight of the API is not more than 80%, not more than 60%, suitably not more than 40%, suitably not more than 30%, suitably not more than 25%, suitably not more than 20% of the total weight of the API and vitamin E TPGS. In one embodiment the weight of API is not more than 30% of the total weight of API and vitamin E TPGS. By way of example, formulation 1 in Example 1 consists of 95.6mg of eltrombopag bis-monoethanolaime, corresponding to 75mg of eltrombopag, and 382mg of vitamin E TPGS, then the weight of eltrombopag of the total weight of eltrombopag and vitamin E TPGS is 164% (75/(75+382)) In one embodiment the weight of API is at least 2%, suitably at least 4%, suitably at least 5%, suitably at least 10% of the total weight of API and vitamin E TPGS. In one embodiment the weight of API is at least 4% of the total weight of API and vitamin E TPGS.

In one embodiment vitamin E TPGS is the only surfactant in the pharmaceutical composition of the invention. In one embodiment the pharmaceutical composition of the invention, preferably in an oral dosage form, consists essentially of or consists of API, solvate or a pharmaceutically acceptable salt thereof and vitamin E TPGS. Besides vitamin E TPGS, additional surfactants and/or lipids could be added to the pharmaceutical composition of the invention. Typically one or two additional surfactant could be added. Alternatively or additionally one or two lipid could be added. Typically one additional surfactant could be added. Alternatively or additionally one lipid could be added. In one embodiment the pharmaceutical composition of the invention comprises API, solvate or a pharmaceutically acceptable salt thereof, vitamin E TPGS, Span 80, miglyol 812N, Labrasol. In one embodiment the pharmaceutical composition of the invention comprises API, solvate or a pharmaceutically acceptable salt thereof, vitamin E TPGS and at least one more pharmaceutically acceptable excipients. In one embodiment the at least one more pharmaceutically acceptable excipients include an anti-oxidant. In one embodiment the weight of the anti-oxidant is not more than 10%, suitably not more than 7%, suitably not more than 5%, suitably not more than 3%, suitably not more than 1%, of the total weight of the pharmaceutical composition. Preferably there is only one anti-oxidant in the composition. In one embodiment the anti-oxidant is selected from the list consisting of Vitamin E Butylhydroxytoluol (BHT) Butylhydroxyanisol (BHA) Propyl gallate, ascorbyl palmitate, ascorbic acid, EDTA and sodium metabisulfite or a mixture thereof, suitably 2 of the anti-oxidants from the list, preferably only one anti-oxidants from the list. In one embodiment the anti-oxidant is vitamin E. In one embodiment vitamin E is not more than 15%, suitably not more than 7%, suitably not more than 5% of the total weight of the pharmaceutical composition. In one embodiment vitamin E is 2-15%, suitably 2-10%, suitably 5% of the total weight of the pharmaceutical composition. In one embodiment the anti-oxidant is BHT. In one embodiment BHT is not more than 3%, suitably not more than 1%, suitably not more than 0.5%, suitably not more than 0.2%, suitably not more than 0.1 % of the total weight of the pharmaceutical composition. In one embodiment the anti-oxidant is BHA. In one embodiment BHA is not more 3%, suitably not more than 1%, suitably not more than 0.5%, suitably not more than 0.2% of the total weight of the pharmaceutical composition. In one embodiment the anti-oxidant is Propyl gallate. In one embodiment Propyl gallate is not more than 3%, suitably not more than 1%, suitably not more than 0.5% of the total weight of the pharmaceutical composition. In one embodiment the anti-oxidant is EDTA. In one embodiment weight of EDTA is not more than 10%%, suitably not more than 5%, suitably not more than 2% of the total weight of the pharmaceutical composition. In one embodiment EDTA is 1-5%, suitably 1-3%, suitably 2% of the total weight of the pharmaceutical composition. In one embodiment EDTA is in the form of disodium salt and the weight of EDTA is calculated based on the weight of EDTA disodium. In one embodiment the pharmaceutical composition consists essentially of or consists of an API, a solvate or a pharmaceutically acceptable salt thereof, vitamin E TPGS and only one anti-oxidant. There exists trace amount of vitamin E (about 1.5%) in vitamin E TPGS of GMP standard. This amount of vitamin E is generally regarded as impurities unless otherwise specified in this application. In one preferred embodiment the anti-oxidant is EDTA. In one embodiment the pharmaceutical composition comprises an API or a pharmaceutically acceptable salt thereof, vitamin E TPGS and EDTA. In one embodiment the pharmaceutical composition consists essentially of or consists of an API, vitamin E TPGS and EDTA. Without wishing to be bound by the theory, the effect of vitamin E TPGS could be attributed to partial solubilization of the API in Vitamin E TPGS, which upon contact with aqueous media forms micelles and thus minimizes the interaction of polyvalent cations, e.g. calcium, with the drug. Eltrombopag, even in the form of bis-monoethanolaime salt, has low solubility in water as well as in a number of liquid/semisolid surfactants (data not shown). However it has been found that other surfactants/lipids also exhibit anti- calcium effect. Without wishing to be bound by the theory, this anti-calcium effect could be plausibly attributed to solubilization or partial solubilization of eltrombopag in such surfactants/lipids containing formulation, which upon contact with aqueous media forms colloids or vesicles, such as micelles or liposomes or microemulsion, and thus minimizes the interaction of polyvalent cations, e.g. calcium, with the drug. Thus the present invention relates to a pharmaceutical composition (pharmaceutical composition of the invention), preferably in an oral dosage form, comprising an API or a pharmaceutically acceptable salt thereof and at least one colloid or vesicle forming agent. The term “vesicle” or “colloid”, as used here, can be broadly understood as spherical or non-spherical structures formed by amphiphilic molecules in an aqueous medium. The term “at least one colloid or vesicle forming agent” includes at least one micelle or liposome or microemulsion forming agent. Thus, the pharmaceutical composition of the invention comprises eltrombopag or a pharmaceutically acceptable salt thereof and at least one micelle or liposome or microemulsion forming agent. A micelle forming agent, liposome or microemulsion forming agent are not mutually exclusive. Some agents can form either micelle or liposome or microemulsion depending on the process or on the presence of other components in the medium. Micelle is generally understood as a spherical structure with diameter about 1 to about 50 nm, about 1 to about 30 nm, about 1- about 20nm, about 1- about 10nm, formed with a single layer of amphiphilic molecules with the hydrophilic head directing towards the aqueous phase outside and the lipophilic tails forming a lipophilic compartment at the inside. Liposome is generally a bigger spherical structure with diameter about 30 to about 10000 nm, formed by one or more lipid bilayer(s) surrounding an aqueous inner core. Suitably the vesicle of the present invention is in the size range of about 1- about 5000 nm, about 1- about 3000 nm, about 1 –about 1000 nm, about 5-about 500 nm, about 5-about 100nm, about 5- about 30nm. The term colloidal-particle is understood as particles in the size range of about 5 to 10000nm which could be non-spherical and could be single layer or more layers. These colloidal-particles could comprise of polymers alone or in combination of surfactants and lipids. Microemulsion is generally understood as dispersed droplets in the size range of about 10 to about 10000 nm, oily droplets stabilized by a surfactant layer. The term “at least one micelle or liposome forming agent” as used here, refers to an amphiphilic molecule that is capable of forming micelles or liposomes in an aqueous medium. Typically the concentration of the at least one micelle or liposome forming agent comprised by the pharmaceutical composition of the present invention is above the critical micelle concentration (CMC) or above the critical liposome concentration (CLC), suitably CMC or CLC at 37±0.5C° in an aqueous medium or in water, upon release from the composition into the medium. Suitably the aqueous medium is gastric fluid or gastric fluid simulates. Suitably the aqueous medium is small intestine fluid or small intestine fluid simulates. Typically the micelles or liposomes or microemulsions formed by the at least one micelle or liposome or microemulsion forming agent of the invention is capable of preventing or partially prevention the interaction of the API and the polyvalent cations, e.g. calcium, present in the medium. The in vitro dissolution test as described in EXAMPLE 4 is an easy and effective method of screening suitable micelle or liposome or microemulsion forming agents for the purpose of the present invention. Vitamin E TPGS was selected through this dissolution test as effective in mitigating the calcium effect on eltrombopag. Such effect was further confirmed in the Macroflux tests (PAMPA assays EXAMPLE 8). A micelle/liposome/microemulsion forming agent for the purpose of the present invention should be pharmaceutically acceptable. Regulatory health authorities provide guidance of pharmaceutically acceptable excipients (e.g. https://www.accessdata.fda.gov/scripts/cder/iig/index.cfm). Furthermore the minimum concentration needed for a particular micelle forming agent for the purpose of the invention, e.g. above CMC in aqueous medium, should not exceed its maximum amount as set forth by the regulatory health authorities. For example 764 mg of Vitamin E TPGS is the maximum daily amount allowed for children older than one 1 year. In one embodiment the present invention relates to a pharmaceutical composition (pharmaceutical composition of the invention), preferably in an oral dosage form, comprises an API or a pharmaceutically acceptable salt thereof and phospholipids. Preferably the phospholipids are pharmaceutically acceptable. Phospholipids are surface‐active, amphiphilic molecules, which comprise a polar head group and a lipophilic tail. The diacyl-phospholipids (DA-PL) comprise a glycerol backbone, which is esterified in positions 1 and 2 with fatty acids and in position 3 with phosphate, whereas phospholipids with one fatty acid tail are called “monoacyl-phospholipids” (MA-PL) or “lyso-phospholipids”. In typical membrane phospholipids, the phosphate group is further esterified with an additional alcohol, for instance in phosphatidylcholine (PC) with choline, in phosphatidylethanolamine (PE) with ethanolamine, and in phosphatidylglycerol (PG) with glycerol. Depending upon the structure of the polar region and pH of the medium, PE and PC are zwitterionic and have a neutral charge at pH values of about 7, whereas PG is negatively charged. The most common phospholipid is PC, and PC is the main component of lecithin. Lecithin is described, e.g., in the United States Pharmacopoeia (USP) as a “complex mixture of acetone‐insoluble phosphatides, which consists chiefly of PC, PE, phosphatidylserine, and phosphatidylinositol, combined with various amounts of other substances such as triglycerides, fatty acids, and carbohydrates, as separated from the crude vegetable oil source. It contains not less than 50% of acetone‐ insoluble matter.” Normally, lecithin grades containing more than 80% PC do not comply anymore with the phamacopoeial definition and are called arbitrarily PC, whereas grades containing less than 80% PC can be arbitrarily called lecithin. As understood by a skilled person, phospholipids, normally extracted from natural sources, is a mixture in which DA-PL is the predominant species over MA- PL. DA-PL is further a mixture with different phosphatidyl derivatives and different length and saturation of the fatty acids. Here below the two tables indicate the composition of lecithin obtained from different natural sources. Although phospholipids can be chemically synthesized, it is cheaper and environmental friendlier to obtain phospholipids from natural sources. Table 2.

Fatty acid composition of typical batches of vegetable deoiled lecithins (area %)

In one embodiment the phospholipids is diacyl-phospholipids. In one embodiment the phospholipids is lecithin. The company Lipoid (https://www.lipoid.com/en/node/10) produces a big variety of phospholipids products suitable for the present invention, which includes but not limited to Lipoid 16:1/18-1, Lipoid , DMPG NA, Lipoid P 75, Lipoid S 80, Lipoid S, Lipoid R, Lipoid E and Lipoid E PG/DSPG. Synthetic DA-PLs, such as Lipoid PC, Lipoid PE, Lipoid PG, Lipoid PA, Lipoid PS can also be purchased from Lipoid catalog. The Company ALC (http://www.americanlecithin.com/aboutphos.html) also offers a variety of phospholipids. In one embodiment the phospholipids is negative charged. It has been observed that pharmaceutical composition of the present invention comprising negative charged phospholipids exerts stronger anti-calcium effect than neutral charged phospholipids at pH values of about 7. Without wishing to be bound by the theory, negatively charged phospholipids can have the anti-calcium effect by additionally capturing positively charged calcium. Thus in one embodiment the phospholipids is negatively charged. In one embodiment the phospholipids is lecithin. In one embodiment the phospholipids is phosphatidylglycerol. In aqueous medium diacyl-phospholipids normally form liposomes. The participation of surfactant in the formation of vesicles increases the curvature, which results in liposomes with smaller diameter or results in thermodynamically stable micelles. The addition of surfactant, such as monoacyl-phospholipids or bile salt, reduces the viscosity of the formulation. Thus in one preferred embodiment, the pharmaceutical composition comprises eltrombopag or a pharmaceutically acceptable salt thereof, diacyl- phospholipids and at least one surfactant, preferably one surfactant. In one embodiment the at least one surfactant is monoacyl-phospholipids. In one embodiment the at least one surfactant is bile salt. In one embodiment the at least one surfactant is vitamin E TPGS. In one embodiment the pharmaceutical composition comprises diacyl- phospholipids and monoacyl-phospholipids. Typically the molar ratio between monoacyl-phospholipids and diacyl-phospholipids is from at least about 1:20 to up to about 1:4, to up to about 1:3, to up to about 1:2, to up to about 1:1. In one embodiment the pharmaceutical composition comprises diacyl- phospholipids and at least one bile salt, preferably one bile salt. Typically the molar ratio between diacyl-phospholipids and the bile salt is from about 3:1 to about 1:3, from about 2:1 to about 1:2 and more typically about 1:1. In one embodiment the pharmaceutical composition comprises diacyl- phospholipids, monoacyl-phospholipids and at least one bile salt, preferably one bile salt. Suitable bile salts include, but not limited to, sodium cholate, sodium deoxycholate, sodium chenodeoxycholate, sodium lithocholate, sodium ursodeoxycholate, sodium hyodeoxycholate, glycine conjugated sodium glycocholate, sodium glycodeoxycholate, sodium glycochenodeoxycholate, sodium glycoursodeoxycholate, taurine conjugated sodium taurocholate, sodium taurodeoxycholate, sodium taurochenodeoxycholate.

In one aspect the present invention relates to a method of manufacturing the pharmaceutical composition comprising the steps of mixing the API or a pharmaceutically acceptable salt thereof and phospholipids in a solution (Solution). Thus the resulting pharmaceutical composition is in the liquid form, which can be administered as oral solutions, as concentrated solutions to be filled in capsules or dosed by pipetting a small volume in a drink like water or juice. Organic solvent in the Solution can be evaporated to result in solid or semi-solid cake. Such cake can be directly formulated into tablets or filled into capsules. Optionally such case can be re-hydrated with water to arrive at a solution, that can be filled into capsules. The capsule is preferably sealed by banding. Alternatively the pharmaceutical formulation of the present invention comprising phospholipids is in solid form. Typically the Solution can be dried in the presence of a sugar (Van Hoogevest, European Journal of Pharmaceutical Sciences, Vol 108, Page 1-12, 2017). Alternatively, in order to convert unsaturated mono- and diacyl-phospholipids into powders organic (ethanolic) solvent solutions of the phospholipids can be mixed as explained in WO2003063835A with absorbing porous carriers like Neuselin Grade 2 (Fuji Chemicals) and subsequently the solvent is removed under vacuum . Furthermore CA2352178 teaches a method of mixing the phospholipids containing solution with polymers, dry and grind to obtain a free flowing powder. The present invention relates to a pharmaceutical composition (pharmaceutical composition of the invention), preferably in an oral dosage form, comprising an API or a pharmaceutically acceptable salt thereof and at least one surfactant. Suitably the term “at least one surfactant” refers to one, two, three or four surfactants present in the pharmaceutical composition of the present invention. Suitably the term “at least one surfactant” refers to one, two or three surfactants present in the pharmaceutical composition of the present invention. Suitably the term “at least one surfactant” refers to one or two surfactants present in the pharmaceutical composition of the present invention. Suitably the term “at least one surfactant” refers to only one surfactant present in the pharmaceutical composition of the present invention. An empirical system known as hydrophilic /lipophilic balance (HLB) is commonly used to categorize amphiphilic surfactants by the degree of affinity for the oily phase compared to aqueous phases in a formulation. Reference : Source of above figure Gattefosse The HLB of a surfactant can be determined by analytical methods and referred to as practical HLB. Alternatively the HLB value can be obtained theoretically. For nonionic surfactants the common way to calculate HLB is called Griffin method (Griffin, William C. (1954), "Calculation of HLB Values of Non- Ionic Surfactants" (PDF), Journal of the Society of Cosmetic Chemists, 5 (4): 249, archived from the original (PDF) on 2014-08-12, retrieved 2013-05-25). Practically surfactants providers usually provides information on HLB value. HLB value can vary to certain degree, for example ±3, ±2 or ±1 between different providers or between different batches of the same provider largely due to varying degree of polymerization, e.g. the number of PEG repeats. HLB values of commonly used and/or commercially available surfactants are collected from general literature, including product catalogs and are presented in Table 4. According to the Gattefosse diagram above, the surfactant suitable for the present invention is typically in the range of water dispersible surfactant, preferably in the range of aqueous solubilizers. Typically the API is at least partially solubilized by the aid of the at least one surfactant. The working surfactant examples suggest that surfactant suitable for the present invention is likely more towards the hydrophilic end of the diagram above. Thus in one embodiment the at least one surfactant has a HLB value above 7, about 8, above 9, preferably above 10, more preferably above 11. The HLB value should be viewed with certain degree of flexibility due to the variation range of ±3, ±2 or ± 1 in practice. In one embodiment the at least one surfactant has a HLB value below 20, below 18, preferably below 17, more preferably below 16. In one embodiment the at least one surfactant has a HLB value in the range of 9-20, preferably 10-19, preferably 10-18, preferably 11-17, more preferably 12-16. The surfactant suitable for the present invention is preferably a polyethoxylated / polyethylene glycol / PEG fatty acid ester derivative, such as PEG 40 hydrogenated castor oil (Cremophor RH 40), PEG 35 castor oil (Cremophor EL), PEG 32 monostearate (Gelucire 48/16), PEG 15 hydroxystearate (Solutol HS 15), or Vitamin E TPGS (d-α-tocopheryl PEG 1000 succinate) or mixtures thereof. The respective HLB of about 14-16, 12-14, 12, 14-16, or 13 of the above molecules is related to but not exclusively dependent on the number of ethylene oxide repeat units in the PEG chain.

Without further elaboration, it is believed that one skilled in the art can, using the preceding description, utilize the present invention to its fullest extent. The following Examples, therefore, are to be construed as merely illustrative and not a limitation of the scope of the present invention. EXAMPLES EXAMPLE 1 Capsules comprising different amount of vit E TPGS Capsules comprising eltrombopag olamine and Vitamin E TPGS shown in Table 5 were prepared. Table 5 *Free acid equivalent * As used in the tables of the Examples, %w/w indicates each components’ weight percentage of the total composition. For example ETB11595.6mg is the 20% of eltrombopag bis-olamine of a total of 477.6 mg of the composition (drug load). Hard gel capsules were prepared as follows: VitE TPGS is first melted at 60-70C in a suitable container depending on the batch weight. Then compound is added and continuously mixed with a homogenizer. Aliquots equivalent to the fill weight are filled into the body of the capsules and allowed to cool to room temp. In case of hard capsules, the body is closed with the cap. The body and cap of this two-piece hard shell capsule is securely sealed. The sealing can be done either by spraying a small amount of a water/ethanol mixture at the cap and body interface followed by a gentle warming to fuse the two capsule parts together or by capsule banding process where a thin layer of gelatin or HPMC is placed over the edge of the capsule cap and body. In both cases, specialized automated machines can be employed. Example 2 Capsules comprising eltrombopag, Vit E TPGS and various anti-oxidants Table 6 Table 7 Capsule formulations containing Eltrombopag, vit E TPGS and an anti-oxidant were manufactured in a similar manner as described in example 1. The anti- oxidant was added after vit E TPGS was melted and it is further mixed by stirring. Drug was added then to the mixture. Whenever possible, it is preferred to avoid/reduce oxidative stress during the manufacture process and to minimize exposure to water during storage. Example 3 Capsule formulations comprising eltrombopag and various surfactants Table 8 Capsule formulations containing eltrombopag and various surfactants were manufactured in a similar manner as described in example 1. Table 10 (formulation 11) 50mg ETB115 is suspended in 1ml of the above preconcentrate. (2 x size 0 capsules each with 0.5ml of the formulation = equivalent to 50mg ETB115 was tested for dissolution in MOPS + SIF buffer) Example 4 Dissolution test Reagents MOPS Buffer e.g. Sigma Aldrich, AR grade or equivalent (3-morpholinopropane-1- sulfonic acid) SIF powder e.g. Bio-relevant, FaSSIF/FeSSIF/FasssGF powder or (Sodium taurocholate + equivalent Lecithin) Dissolution Condition Test Medium MOPS+SIF Buffer Dissolve 20.9 g of MOPS buffer in 1 liter of water and mixed well.

In dissolution profiles, Samples are required to collect at 30, 45, 60, 90 and 105 minutes (Infinity testing at 200rpm). Do not replace the medium removed. At each time point, withdraw 10 mL of the solution and immediately filter through a Pall Acrodisc PSF GxF/Glass 1 µm Automated Certified syringe filters (recommended) or ROBY25/GF55 glass fiber filter 0.7 µm. Collect the test solution into a container for UV measurement. Calcium challenge At 30 minutes prior to adding the dosage form, 139mg, procedure: 1185mg, 1249mg of calcium chloride, equivalent to 50 mg or 427 mg or 450 mg of calcium element, is added and allowed to dissolve completely. After 30 minutes, add the dosage form and consider this as time 0 for defining the dissolution profile. Sampling time for profile generation may be adapted based on project need.

Reference solutions This corresponds to 0.055 mg/mL as free acid of ETB115 Wavelengths Sample wavelength 424 nm Dissolution test according to EXAMPLE 4 was carried out for formulation 1 in 75mg in comparison to Promacta. As shown in Figure 1, vitamin E TPGS has effectively maintained the dissolution rate in the presence of excessive amount of calcium. The anti-calcium effect by other surfactants or mixture of surfactants is shown in Figure 4. Data in Figure 4 were generated following EXAMPLE 4 a. 0.5% Gelucire 48/16 (0.5% = 4.5grams) was added to 900ml MOPS + SIF buffer, b. after 40minutes - 427mg Ca (solution) was added to the above media. c. After 30minutes - the Promacta 75mg tablet was added to this media (containing Gelucire 48/16 and Ca) and tested for dissolution. d. Separate “Control - without the addition of calcium” dissolution was also done for comparison. Similarly, other suitable surfactants can be selected as above. Following the teaching of this example, the effect of surfactant on the API of the Invention can be tested. EXAMPLE 4A Modifications of dissolution test The above dissolution test was designed for eltrombopag. Minor modifications depending on the compound to be tested is recommended for the optimal results. For example each one of the below parameters or any combination thereof can be adjusted depending on the compound to be tested and the chelating metal to be tested. Speed of rotation 75±3 rpm or 100 ± 4 rpm Note Selection of rotation speed to be adapted based on the Drug substance and Drug product properties and type of formulation to be evaluated. Other speed within the common general knowledge can also be chosen. Test medium pH 6.8 MOPS Buffer or pH 6.8 MOPS + SIF buffer Note Addition of SIF (Sodium Taurocholate and Lecithin) and amount of SIF in MOPS buffer to be adapted based on the drug substance properties. In principle the more soluble the drug, the less amount of SIF or no SIF is required if the drug has good solubility. E ^valuation _{Quantitative evaluation performed using suitable quantitation} techniques like UV or HPLC method. Determine the absorbance or peak area in the chromatogram of the test medium, reference and test solutions using a suitable UV-VIS spectrophotometer or HPLC techniques. N _ote ^{Selection of suitable quantification techniques adapted based} on the nature and properties of drug substance and drug product and also Metal ion selected for In vitro assessment of negative food effect. EXAMPLE 5 Impact of vitamin E TPGS concentration and sequence of calcium addition on dissolution To further understand effect of Vitamin E TPGS on drug release, dissolution of 75 mg Promacta® tablets was performed; (1) with different concentrations of Vitamin E TPGS and (2) sequence of calcium addition in MOPS buffer. Dissolution in MOPS buffer to understand the effect of Vitamin E TPGS on % release from 75 mg Promacta ^® tablets Table 12 Results of the dissolution from group with calcium added 30 min before addition of Promacta® tablet showed Vitamin E TPGS concentration dependent release (Figure 3A). As Vitamin E TPGS is increased from 0.1 to 0.5% w/v in dissolution media, the % of drug release at 105 min increases from 50 to 82%. On the contrary, when the calcium is added 60 min after addition of Promacta® tablets, the release is relatively unaffected by the concentration of Vitamin E TPGS at 0.3 and 0.45% w/v (Figure 3B). From above results, the effect of Vitamin E TPGS can be summed up as 1) eltrombopag dissolution shows concentration dependence when calcium is present in the media from the beginning which is likely to be the situation in-vivo, 2) eltrombopag once solubilized in dissolution media in presence of Vitamin E TPGS, effect of calcium mediated drop in dissolution is mitigated. So, partially solubilized suspension of DS in Vitamin E TPGS could contribute to reduce calcium mediated food effect. EXAMPLE 6 Effects of surfactants with different HLB value on drug dissolution HLB solution preparation: HLB-8 solution: Mixed 32.5ml Span-80 and 17.5mlTween-80. HLB-10.7 solution: Mixed 20ml Span-80 and 30mlTween-80. HLB-12.8 solution: Mixed 10ml Span-80 and 40mlTween-80. Dissolution media Preparation: 0.1% solution of HLB-4.3 (Span-80) in MOPS: Mixed 2ml of SPAN-80 with 2000ml of MOPS buffer. Mixed well. 0.1% solution of HLB-8 in MOPS: Mixed 2ml of HLB-8 with 2000ml of MOPS buffer. Mixed well. 0.1% solution of HLB-10.7 in MOPS: Mixed 2ml of HLB-10.7 solution with 2000ml of MOPS buffer. Mixed well. 0.1% solution of HLB-12.8 in MOPS: Mixed 2ml of HLB-12.8 Solution with 2000ml of MOPS buffer. Mixed well. 0.1% solution of HLB-15.0(Tween-80) in MOPS: Mixed 2ml of Tween-80 with 2000ml of MOPS buffer. Mixed well. Control Preparation: Dropped 1 Promacta tablet, kept in sinker in 900ml with respective dissolution media. After each specified time point, sample was withdrawn automatically and filtered through ROBY 25/GF 55 Filter. Dissolution results are given in Fig.5A. With 427mg calcium Preparation: Added 1185mg CaCl2 30 minutes before dropping 1 Promacta tablet. Dropped 1 tablet, kept in sinker in 900ml with respective dissolution media. After each specified time point, sample was withdrawn automatically and filtered through ROBY 25/GF 55 Filter. Dissolution results are given in Fig.5B. The results showed that with surfactants with higher HLB value resulted in higher solubilization of ETB115 and had stronger anti-calcium effect. Similar trend can be expected if ETB115 is replaced with another API of the Invention. EXAMPLE 7 Compositions comprising phospholipids Lipid based formulations were prepared with varying ratio of the components as per weights in Table 13. Lipoid E80 S(Cas No.93685-90-6), glycocholic acid, glycerol and ETB115 were first dissolved in organic solvent in a round bottom flask to obtain a optically clear solution and then solvent was evaporated gradually, which results is solid gel like cake. The resulting solid gel cake readily disperses with water with brief use of sonication and heat. The resulting viscous fluid gel like formulation was filled into hard gelatin capsules by weight and allowed to cool to room temperature. The body is closed with the cap and used for dissolution studies. Alternatively the resulting solid gel cake can be directly filled into capsules by further extrusion or can be hydrated with required amount of non- aqueous hydrophilic or lipophilic solvent for filling in soft gel capsules. The lipid particles size tested upon dilution with water were found to be around 190nm in size with good uniformity as determined by Malvern dynamic light scattering technique. We anticipate that the true particle size of the formulations would be much smaller if tested undiluted. Surprisingly, we found that lipid: drug weight ratio of 5:1 or 9:1 have almost same degree of drug associated, it was 94% for 5:1 vs 104% for 9:1 ratio signifying almost majority of drug is associated with the lipid or micelle. Association was measured by filtration through 0.2 micron filter and concentration of the filtrate was assessed using Liquid chromatography. The addition of bile salt and glycerol improves the dispersion and hydration time. The increasing amount of bile salt decreases the mixed micelles particle size. Furthermore, upon dilution with GI simulated fluids, these particles were found be stable in both Fed (FeSSIF) and Fasted (FaSSIF) state simulated media as observed by no dramatic change in the particle size. In fact, in presence of Fed state media, the lipid based mixed micelle formulation dispersed more readily into micelle-based formulation. Formulation also showed increased solubility in both fast and fed simulated GI fluids which justifies that compound had less tendency to precipitate upon dilution and a lipid dispersion is formed upon dilution (Table 15). Lastly, the improved solubility of more than 100x upon dilution with bio relevant media translated to enhanced dissolution in dissolution studies (following the protocol as described in EXAMPLE 4) when compared to control Promacta formulation. Mixed micelle formulation L-F2 showed >90% dissolution within 30min and showed that negative effect of calcium on dissolution is being mitigated by using lipid based mixed micelle formulation. Lipid complex with hydrophillic co-solvent (F3 and F4): To prepare lipid complex, capsules were prepared as per weights in Table 14. Lipoid P LPC (Cas No.9008-30-4) or Lipoid E80 S, PEG 300 co- solvent and ETB115 were first dissolved in organic solvent (DCM/Methanol 1:1) in a round bottom flask and then solvent was evaporated which results is solid cake. This solid cake is then hydrated with required amount of distilled water which results into a highly viscous gel like formulation. Upon, rehydration the fliud aliquots equivalent to the fill weight and filled into the body of the capsules and allowed to cool to room temperature. In case of hard capsules, the body is closed with the cap. These lipid complex formulation dispersed with water with brief use of sonication and heat. The lipid particles formed after hydration with water are around 31nm in size (LPC lipid L-F4) and around 490nm (Lipoid E 80S L-F3) with good uniformity as determined by malvern dynamic light scattering tecnhique. The compoisition L-F4 was selected based on the highest association, stability upon dilution with biorelevant media and also due to the small micelle like particle formation. The wieght ratio of 7:1 was found to provide the highest level of association/entrapment of drug, close to 100%. Alternatley, 5:1 ratio can also be utilized as it shows minimum impact on association (L-F4-B) Lipid complex formulation showed enhanced stability upon dilution in biorelevant media as evident by no major change in size (Table 15) and also provided better solubility. The enchanced solubility in biorelevant media also resulted in better dissolution profile (70-80% in 60 min) compared to control Promatca in the dissolution studies described in EXAMPLE 4. The results are shown in Figure 6. Although, the dissolution of F3 was low, we believe that F3 formulation could be furthur optimized to improve solubility and stability as we had some technical processing challenges while scaling up the formulations. In summary, it was demonstrated that lipid based formulation, mixed micelle or lipid complexes both can facilitate high association of the compound with lipids which in turn resulted in improved solubilization upon dilution in GI biorelevant media and provided close to complete dissolution of drug in presence of calcium where perhaps compound was shielded from interaction with calcium. Examples L-F2 Table 13. Capsules comprising Lipid based Micelles with bile acid are shown below: *Free acid equivalent * As used in the tables of the Examples, %w/w indicates each components’ weight percentage of the total composition. For example ETB11595.6mg is the 5.5% of eltrombopag bis-olamine of a total of 1638 mg of the composition (drug load). Examples L-F4 and L-F3 Table 14. Capsules containing Lipoid P LPC, Lipoid E 80 S Lipid complex formulations are shown below: *Free acid equivalent * As used in the tables of the Examples, %w/w indicates each components’ weight percentage of the total composition. For example ETB11595.6mg is the 11.4% of eltrombopag bis-olamine of a total of 744.36 mg of the composition (drug load). Table 15. Particle size and solubility data for L-F2 mixed micelle and L-F4 lipid complex formulations Similarly lipid formulations comprising API other eltrombopag can be prepared according to the teaching of this example. EXAMPLE 8 PAMPA test A study combining the experimental determination of dissolution and simultaneous flux through an artificial lipidic membrane was conducted on a 12.5, 25, 50 and 75 mg dose of Promacta and a 55 and 75 mg dose of formulation 1 (in Capsule) of the invention. In addition, a mixed micelle formulation (F2) was evaluated at a 37 mg dose. FaSSIF media was prepared according to instruction from biorelevant.com. Additionally, each media are prepared containing 450 mg of elemental calcium, to mimic a high calcium meal and understand the impact of calcium and dissolution and resultant flux. This was achieved by adding calcium chloride to the media. The media are added, 900 mL in total, to a USP II apparatus, equipped with a paddle attachment for stirring. The dosage unit was introduced to each media. Dissolution analysis were conducted in each media: FaSSIF, V2; FaSSIF, V2 + Calcium. This described set-up is considered the donor compartment. A receiver compartment was introduced into the USP II dissolution set-up. This consists of a minaturized USP II paddle set-up. The bottom of the vessel has a 0.45 um PVDF membrane. Concentrations of eltrombopag in the donor vessel and receiver vessel are monitored with fiber optic probes. The capsule formulation containing about 80% vitamin E TPGS, as well as the F2 formulation has improved the Fasted + High Calcium/Fasted flux ratio significantly: Ratio of 0.9 for the 55 mg dose and for the F2 formulation (compared to 0.2 for Promacta @ 50 mg dose); Ratio of 0.7 for the 75 mg dose (compared to 0.3 for Promacta @ 75 mg dose). PAMPA test can be used or modified if needed to test the anti- calcium effect on other APIs according to the teaching of the present invention. EXAMPLE 9 Food effect study in health volunteers The effect of food, high and low in calcium content, on the pharmacokinetics of an API of the Invention after administration of the pharmaceutical composition of the invention (e.g. capsule comprising (80% w/w vitamin E TPGS and 20% w/w of API) will be investigated. The treatment will consist of single oral doses administered in a fasted state, and in various fed conditions: high-fat high-calorie (HFHC) high-calcium meal, HFHC low-calcium meal, high-fat low-calorie (HFLC) low-calcium meal. Subjects will undergo 4 treatment periods with a washout of 7 to 10 days between 2 consecutive doses. The primary objective is to evaluate the effect of food, high or low in calcium, on the API of the Invention pharmacokinetics, including but not limited to the measure of AUC, Tmax and Cmax. EXAMPLE 10 Doxycycline Vitamin E TPGS composition Table 16 Dissolution test was performed substantially similar to EXAMPLE 4 with the following changes: Sample time is 10,15,30,45,60,75, 90min; Paddle rotation speed was 75 rpm; Test medium: pH 6.8 MOPS Buffer; Calcium element concentration: 427mg calcium; Wavelength : 274nm. The calcium effect on Doxycycline is mitigated by the presence of Vitamin E TPGS as shown in Fig.8.
