Title:
ANTI-TUMOR PHARMACEUTICAL COMPOSITION AND METHOD FOR INCREASING SOLUBILITY OF COMPOUND
Document Type and Number:
WIPO Patent Application WO/2021/136089
Kind Code:
A1
Abstract:
A quinoline anti-tumor pharmaceutical composition containing a phosphorus substituent and a method for increasing the solubility of a pharmaceutical active ingredient in said pharmaceutical composition, the pharmaceutical composition comprising a pharmaceutical active ingredient and a pharmaceutically acceptable acid. By adding an acid compound to a pharmaceutical active ingredient, acid may be released after a drug has entered the gastric juice, thereby increasing the acidity of the gastric juice and lowering the pH value of the gastric juice. The decrease in the pH value of the gastric juice provides a favorable environment for the dissolution of the drug, thus facilitating the dissolution and absorption of the pharmaceutical active ingredient within the stomach, and improving the bioavailability of the drug within the body. Also provided is a method for increasing the solubility in water of a quinoline anti-tumor drug containing a phosphorus substituent.
