Technical problem Technical problem which is solved by this invention consists of a problem how to incorporate the active components, in this case usnic acid sodium salt (sodium salt obtained from usnic acid) and essential oils from the upper parts of medical plants (sage Salvia officinalis L., fennel Foeniculum vulgare L., thyme Thymus Vulgaris L., or peppermint Mentha piperita L.) or menthol, into suitable base, which is the best way to preserve their active properties, caused by synergistic effect of above mentioned active principles and to provide simple application for disinfection of mouth and throat.

Back, around of the invention There are already known preparations for disinfection of mouth and throat, with incorporated active components containing additives (essential oils, extracts, tinctures,...), or medicinal parts of herbal drugs (sage, fennel, thyme, or pepprmint).

Sage-Salvia officinalis L. is a carminative, spasmolytic, antiseptic, astringent and diarrhoic. It neutralizes influenza virus and enhances leukocytes function (phagocytic activity). Leaf is used, and it is an antiphlogistic, stomachic, antisudorific, spice, especially its essential oil as an antiseptic. Sage leaf is used as a gargle for inflammation of the mouth and throat, digestive complaints, flatulence, inflammation of the intestinal mucosa, in diarrhoea, as an antisudorific (antihydrotic), against night sweats in tuberculosis patients, but also against excessive sweat formation of psychosomatic origin.

In folk medicine, because of an inhibiting effect on the secretion of milk, garden sage is also used to aid the cessation of lactation; it is also said to have mild hypotensive and emmenagogic effects. The ancient physicians were using sage very much against chronic lung illnesses and as a rinse for inflammation and catarrh of the mouth and troath.

Traditionally, it is used against dyspepsia, pharyngitis, uvultis, stomatitis, gingivitis, glossitis, hyperhydrosis and galactorrhoea. Spanish oil does not contain thujone, instead, the share of cineole is greater. The oil Salvia triloba contains just a small amount of thujone, and because of its high content of cineole, it reminds of eucalyptus oil, by the odour. Diterpenoid bitter substances Carnosol (Picrosalvin) which is additionally contained in Dalmatian and Greek sage, are missing in Spanish sage. Carnosol and ringlike open form, which is not bitter, carnosic acid, cannot be obtained by steam distillation, but by extraction of the drug with petrol. Sage also contains triterpenoid acids (Ursol-and Oleanol-acid), flavonoids and tannins. Salvigenin, 5-hydroxy-6,7,4- trimetoxy-flavone is characteristic for Salvia triloba, and is used to detect forgery.

Table 1.

The essential oil contains approximately 60% of anethole, 12% of fenchone, methylcavicol, 0-pinne, canphene, etc. There is fatty oil, comprising 60% of petroselenic acid, 22% of oleic acid, 14% of linolenic acid, and 4% of palmitic acid, in the fruit. The drug contains quercetin, flavons and insufficient amount of essential oil.

The fruits are gathered in phase of puberty. In folk medicine, it is used as a galactagogue for lactating women, and externally as an eye lotion (decocotion) and in functional visual disorders. Fennel is also used for appetite enhancement. Fennel fruit possesses a carminative, aromatic, antiinflammatory, antimicrobial and diuretic action. Recently, fennel is more often used as an expectorant (secretolytic, secretomotoric, antiseptic), spasmolytic, and carminative. Fennel fruit and preparations thereof are used in disturbed intestinaldriving functions, in spasmic colitis, and meteorism. The fruits of fennel- Fructus Foeniculi are used, and they contain 2-6% of essential oil and 9-12% of fatty oil ; in addition, essential oil-Oleum Foeniculi, colourless to weakly yellowish liquid, comprising fenchone and anethole as main constituents. Fennel is a mild expectorant, mostly for children. It is considered to counteracts cramps, even to possesses mild narcotic action. Fennel is an excellent corrigent of taste in carminative tea mixtures.

Fennel tea is used against dyspepsia and diarrhea in infants. It does not only bring liquid into organism, but, also reduces intestinal meteorism and spasm, using its carminative effect. Pure fennel essential oil reinforces inflammation, and has an irritant action on the intestinal musculature, and must not be used for infants or young children because of the danger of laryngeal spasm, dysponea, and excitatory states.

Thyme-Thymus Vulgaris L. is used as a carminative, antispasmodic, antitussive, expectorant, secretomotoric, bactericid, anthelmintic, and astringent. Traditionally, it is used against dyspepsia, chronic gastritis, asthma, diarrhea in children, enuresis in children, laryngitis, tonsillitis, and especially against influenza and bronchitis. Externally, thyme is used as a hyperaemic, antibacterial, and also deodorizing agent in inflammation of the mouth and throat (as a gargle) and as a rubefacient, additive and pot-pourri. In folk medicine, because of its spasmolytic action, it is an important stomachic and carminative, and it is also used as a diuretic, urinary disinfectant, and vermifuge. Thyme is also employed as a spice and in making liqueurs. 1.0-2.5% essential oil contains mainly the isomeric monoterpenes thymol (30-70%) and carvacrol (3-15%), a small portion of the phenols in the drug is present as glucoside or galactoside. In the essential oil, there are other monoterpenes such as p-cymene, C-terpinene, limonene, etc. The composition of the oil depends to a large extent on the origin of and time of harvesting of the drug, the D- terpinene and thymol contents being lower at the end of the vegetative cycle. Both plant sources afford an oil of similar composition, though there are differences in the content of thymol methyl ester: in Thymus Vulgaris it is 1.4-2.5% and in Thymus Zygis only 0.3% of the oil; the monoterpenes accumulated primarily in the peltate glandular trichomes.

Thymus Vulgaris subsp. aestivus from Spain, produces oil characterized mainly by the occurrence of 1,8-cineole (22%), geranoil (17%), and geranyl acetate (20%). The drug also has tannins, flavonoids, and triterpenes. The main constituents of the oil are with 40- 50% of thymol (2-isopropyl-5-methyl-1-phenol) and isomeric carvacrol. Quantitative ratio between the two phenols depends on species, origin, and growth conditions. The oil from Thymus zygis instead of thymol, contains for example almost only carvacrol. The differences between oils containing thymol, that is carvacrol, can be determined by crystallization test. The supplemental constituents of terpene: p-cimol, thymolmonomethylether, linalol, borneol, geranyol and terpene-KW (El-pinene, p- cimene).

The main pharmacological characteristic of thyme is connected with the essential oil (thymol and carvacrol) and favonoids. The thyme oil has hypotensive and respiratory stimulating effect on rabbits, administered orally or intramuscularly and on cats, administered by intravenous injection; it reinforces rhythmical cardiac contractions in rabbits. Crystal thymol is obtained from the thyme oil, from Trachyspemum ammi (L) prague, Ocimum gratissium L., Monada punctataL and Monarda didyma L. It is easily attainable by dehydration of piperitone. Racemic menthol is obtained from thymol by hydration. Thyme oil is secreted at inner line mostly into lung alveoli and thus through lungs, it is in effect, concetrated to the location'of the disorder. Spasmolytic effect at bronchial spasm is a characteristic of thyme, and therefore it became a whooping cough remedy for children and adults suffering from bronchitis with convulsive character of cough. Patients with emphysema and asthma appreciate spasmolytic property of thyme, although it is used only as an auxiliary remedy in long therapy. Scope of its activity is very wide. What is mint for stomach and intestines, thyme is for trachea and bronchi.

Peppermint (Mentha piperita L.) contains up to 4% of essential oil containing minimum of 48% of menthol, menthone, menthofuran and other monoterpenes. The drug also contains up to 12% of tannins, flavonoids, triterpenes. Peppermint is a spasmolytic, carminative, diaforetic, local antiseptic, and virustatic.

Available patent and non-patent literature does not offer any similar, or any process at all, for obtaining of a pharmaceutical preparation on the basis of medical plants (sage Salvia officinalis L., fennel, thyme, or peppermint Mentha piperita L.) or menthol, and usnic acid sodium salt, which is used for disinfection of mouth and throat.

Description of technical problem solution with examples Usnic acid sodium salt and essential oils of medical plants (fennel Foeniculum vulgare L., or sage Salvia officinalis L., or thyme Thymus Vulgaris L or peppermint Mentha piperita L.) and menthol are strong antimicrobial and antifungal agents. The preparation obtained according to the invention comprising these active principles, showing mutual synergistic action, provides its effective use as a disinfectant for upper respiratory tract.

The essential oils built in the preparation according to the invention, show exceptionally high microbiological activity, due to the presence of certain active components. Sage Salvia officinalis L. is used for external application in the form of a gargle or rinse, using antiseptic, fungicidal and antiphlogistic effect of the oil, for treatment of inflammation of oral cavity and pharynx. Applied internally, it inhibits secretion of saliva and sweat. Since thujone has toxic properties, sage preparations must not be given in unfoundedly high doses and for a long period. Sage oils contain: thujone, 1,8-cineole, p-cimen and camphor, thymol and carvacrol. It also contains folic acids- caffeic acid, chlorogenic acid, ellgic acid, ferulic acid, gallic acid, rosmarinic acid, tannins (3-8%). Parallel essential oil Salvia officinalis is produced from different species of Salvia, with reduced total ketones and high content of total alcohol. Thyme Thymus Vulgaris L. essential oil is used internally as an expectorant and bronchospasmolytic, for treatment of acute and chronic bronchitis, cough, catarrh of respiratory tract, secretion, it causes enhanced movement of bronchial fibers. It is the cause of reflex action on stomach, and on the other side, is direct action on bronchial mucous membrane, since the essential oil can be partly secreted through lungs. Antiseptic and bactericidal action of thymol is also outstanding, and it is 25 times stronger than phenol, but it is considerably less toxic than phenol, and it is also a strong fungicid. Thyme contains: thymol, carvacrol.

The content of 0,8-2,6% essential oil is represented by phenols, which are the main ingredients (20-80%), especially thymol and carvacrol, taking p-cimen and 0-terpinen (monoterpenes), linalol, D-terpienol and thujon-4-ol (alcohol) into account. It also contains: flavonoids, caffeic acid, oleic acid, ursolic acid, saponines, tannins. Fennel Foeniculum vulgare L. is used in preparations for treatment of bronchitis as a disinfectant, antiinflammatory agent and expectorant. It contains fenchone, methylcavicol, 0-pinne, canphene. Those species of fennel with high content of essential oil are also characterized by high content of fenchone. Other compounds are: Methylcavicol (Esdragol), anisaldehyde, foeniculin, terpineol. Content of essential oil is 4%: Pepprmint Mentha piperita L. contains: menthol, menthone, menthofuran and other monoterpenes, and their action is enhanced by presence of usnic acid sodium salt, which determins antibacterial effect of the preparation on: Staphylococcus aureus, Echerichia coli, Salmonella sp., Bacillus subtilis, Candida. Synergistic action of some active components of the mixture containing of usnic acid sodium salt and essential oils (fennel, or sage, or thyme, or peppermint) or menthol-shows unexpected improvement in action on pathogenic microorganisms. Such combinations are new, and they are not comprised by the prior art, as well as the effects of the action for disinfection of the mouth and throat.

This pharmaceutical disinfective preparation on the basis of usnic acid sodium salt and medical plants (sage, fennel, thyme, or peppermint) or menthol, is used as a general disinfectant for external use and for treatment of inflammation of uper respiratory tract and oral cavity, caused by action of pathogenic microorganisms. The invention presents obtaining of the preparation in the form of : chewable tablets, tablets, gel, aerosol, as a base for deodorants, aromatic-antiseptic liquid for disinfection, in the form of wet napkin for intimate care, baby powder and other forms for mentioned purpose. The procedure for obtaining of this preparation, according to the invention, is reliable because the active components, in this case usnic acid sodium salt and essential oils preserve their natural properties, because of simplicity of the procedure for obtaining, their original antimicrobial action is neither reduced, nor lost. The advantage of the invention is in choice of active effect (usnic acid sodium salt and essential oils: fennel, or sage, or thyme, or peppermint) or menthol, in simplicity of the process for obtaining, as well as in simple application of the finished form of the preparation. The process used usnic acid sodium salt, obtained by a certain process from lichen Usnea barbata L. Wigg. This substance possesses strong antibacterial activity, particularly in oral cavity and upper respiratory tract. It is a surface antibiotic, of natural origin, which selectively inhibits carriers of an infection, not damaging healthy microflora of the mucous membrane. Peppermint essential oil contains approximately 40-80% of menthol, which is among other components of its composition one of the carriers of antimicrobial activity and aroma of the oil. Its incorporation in the preparation, according to the invention, provides a successful replacement of menthol by peppermint essential oil, not reducing the effect of the finished form of the preparation.

Suggested invention relates to the procedure for obtaining of pharmaceutical disinfective preparation in the form of chewable tablets, in fact, tablets for suckling, that is, solid dose forms, intended for local application of active medical substance to mucous membrane of the mouth and throat.
