Abstract

The invention relates to a preparation method and a quality control method of a new drug, Danazol Vaginal Tablets, for treating endometriosis with clear dysmenorrhea symptom but light physical sign. The drug can be delivered via cavitary mucosa, so as to prevent or relieve the possible adverse reactions due to systemic drug delivery; the effective drug concentration at lesion site is high, so as to be in favor of exert curative action; and the added lactic acid-calcium lactate buffer system results in the drug with pH of 3.5-4.0 that is similar to the physiological pH in vagina, so as to effectively retain physiological environment in vagina, provide existing conditions suitable for vaginal beneficial bacteria, and promote rehabilitation.

Description

technical field [0001] The invention relates to a preparation method and quality control method of danazol vaginal tablets, a new drug for endometriosis with obvious symptoms of gynecological dysmenorrhea but relatively mild signs. Background technique [0002] At present, dysmenorrhea and endometriosis seriously threaten women's health. Although there are many kinds of gynecological drugs, there are certain problems in use and treatment; in addition, there are danazol suppositories on the market, which have problems of storage deformation, melting and loss when encountering body temperature, and contamination of clothes; problems affecting the physiological pH value of the vagina question. [0003] The purpose of the present invention is to overcome the shortcomings of the existing varieties, provide a novel preparation with spectrum, high efficiency, quick effect, stability and good patient compliance and provide a quality control method. Contents of the invention [0...
