Abstract

The invention relates to the technical field of gynecological medical treatment, in particular to a formula for erosion removal vaginal effervescent tablets.The erosion removal vaginal effervescent tablets comprise, by weight, 2.5-3 parts of radix arnebiae seu lithospermi extract, 10-12 parts of citric acid, 8-10 parts of sodium bicarbonate, 20-24 parts of lactose and 2-3 parts of lubricants.A process for preparing the erosion removal virginal effervescent tablets includes preparation steps of dividing the lactose into two portions; uniformly mixing one portion of the lactose with the radix arnebiae seu lithospermi extract and the citric acid to obtain a first mixture; uniformly mixing the other portion of the lactose with the sodium bicarbonate to obtain a second mixture; respectively granulating the first mixture and the second mixture by the aid of 5% PVP (polyvinyl pyrrolidone) absolute ethyl alcohol solution to obtain granules; drying the granules at the temperature of 50 DEG C and uniformly mixing the granules with PEG-6000 (polyethylene glycol-6000) to obtain third mixtures; tabletting and shaping the third mixtures to obtain the erosion removal virginal effervescent tablets.The 5% PVP absolute ethyl alcohol solution is used as adhesive.The formula and the process have the advantages that the virginal effervescent tablets are prepared after effective components in radix arnebiae seu lithospermi are extracted, so that patients can conveniently utilize the vaginal effervescent tablets, each erosion removal vaginal effervescent tablet in a prescription contains an acid source and a carbon dioxide source, each acid source and the corresponding carbon dioxide source can quickly react to each other to generate carbon dioxide gas when in contact with water, accordingly, the tablets can be disintegrated within a short time, principle medicines can be released, medicines can be uniformly released along with foam, and contact between the medicines and the vaginal mucous membranes of the patients can be improved.

Description

technical field [0001] The invention relates to the technical field of gynecological medicine, in particular to a formula and a preparation process of Xiaomi vaginal effervescent tablet.
