Abstract

The invention provides a vaginal effervescent tablet composition that comprises 100 weight portions of active drug ingredients and 20-1000 weight portions of solid lipid. The vaginal effervescent tablet composition of the invention can be released in vagina slowly and continuously, ensuring that the sufferer feels comfortable, and generates foams that can ensure fine drug powder to be uniformly distributed, leading the drug to be uniformly distributed in the inner wall mucosa of the vagina; meanwhile, the foams last for a long time, which prolongs dramatically the even contact time of the drug and the mucosa of the vagina and extends the effect of the drug; furthermore, the vaginal effervescent tablet composition is easily washed out and more beneficial to the health of sufferers.
