Abstract

The invention relates to a method for preparing novel gynecological policresulen vaginal tablet used for antisepsis and anti-inflammation and a quality control method thereof. The policresulen has broad-spectrum antibacterial effect on common gram-positive bacterium, gram-negative bacterium, fungus and some viruses, wherein, anaerobe trichomonas and monilia are particularly sensitive to the policresulen but vaginal lactobacilli flora is hardly effaced. The invention has the advantages that vagina local medication avoids or reduces possible untoward effect caused by systemic administration; highly effective concentration of the medicine on lesion site is in favor of developing therapeutic effect, effectively protecting physiological environment of the vagina and providing suitable life condition for good bacteria; wherein, prescription of 1,000 preparation units of the medicine is: 45-180g of the policresulen, 30-180g of filler lactose, 60-500g of starch, 50-500g of kaolin, 2-10g of bonding agent hypromellose, 6-50g of fluidizer silicon dioxide, 30-300g of disintegrating agent microcrystalline cellulose, 20-200g of polyvinyl polypyrrolidone and 1-10g of lubricant magnesium stearate.

Description

technical field [0001] The invention relates to a preparation method and quality control method of polycresol vaginal tablets, a new antibacterial and anti-inflammatory drug for gynecology. Background technique [0002] At present, trichomonas, bacteria, fungi and other bacterial infectious gynecological diseases seriously threaten women's health. Although there are many kinds of gynecological medicines, there are certain problems in their use and treatment. In addition, there are currently policresol suppositories and solutions on the market, but there are problems such as melting and loss of suppositories, contamination of clothes, and inconvenient use of solutions. [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 [0004] The present inventi...
