Abstract

The invention relates to a preparation method and a quality control method of a new gynecologic drug, Metronidazole, Clotrimazole and Chlorhexidine Acetate Vaginal Tablets, with antibacterial and anti-inflammatory effects. The added lactic acid-calcium lactate buffer system results in a drug with pH of 3.5-4.0 t 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. The main preparation method comprises the steps of compounding, granulating, grading, mixing, and tabletting. The quality control method comprises the steps of collecting one dosage unit of the product, grinding, adding 100mL water, shaking for 10min, and testing pH (should be 3.5-4.0); testing melting time limit (should be 30min); and measuring the nominal content of the three components by high performance liquid chromatography (should be both in the range of 90.0-110.0%).

Description

technical field [0001] The invention relates to a preparation method and a quality control method of a new gynecological antibacterial and anti-inflammatory drug Shuangzotai vaginal tablet.
