Abstract

The invention discloses a pharmaceutical composition containing azithromycin and pharmaceutically acceptable salts thereof for vagina, which are used for treating vagina inflammation.

Description

technical field [0001] The invention relates to a pharmaceutical composition for treating vaginal infection, in particular to a vaginal pharmaceutical composition containing azithromycin pharmaceutically acceptable salt. Background technique [0002] Azithromycin is a semi-synthetic 15-membered macrolide antibiotic that is effective against Gram-positive aerobic bacteria, infections caused by Gram-positive aerobic bacteria, and anaerobic bacteria. However, azithromycin has poor water solubility and is practically insoluble in water, therefore, the antibiotic is not well absorbed. The azithromycin is made into a pharmaceutically acceptable salt, and the water solubility is greatly improved, which is beneficial to the absorption of the drug. The pharmaceutically acceptable salt of azithromycin has good curative effect on pelvic inflammatory disease and vaginitis caused by Chlamydia trachomatis, Neisseria gonorrhoeae and Mycoplasma hominis. [0003] CN101077352A discloses an ...
