Abstract

A vaginal effervescent tablet of miconazole nitrate is proportionally prepared from miconazole nitrate, tartaric acid, sodium dicarbonate, microcrystalline cellulose, polysorbitate, carboxymethyl starch sodium and magnesium stearate.

Description

technical field [0001] The invention relates to miconazole nitrate vaginal effervescent tablet and a preparation process thereof. Background technique [0002] Miconazole nitrate is a synthetic 1-phenylethyl imidazole derivative, and its active ingredient is miconazole. This drug can interfere with the activity of cytochrome P450, inhibit the biosynthesis of ergosterol in the fungal cell membrane, change the permeability of the membrane, and cause the leakage of intracellular substances; it can also inhibit the biosynthesis and oxidase of fungal triacylglycerol and phospholipid And the activity of peroxidase, causing the accumulation of hydrogen peroxide in cells, resulting in cell submicrostructural degeneration and cell necrosis. The drug can also inhibit the process of Candida albicans transforming from spores to invasive hyphae. This drug is a broad-spectrum antifungal drug, which has inhibitory and bactericidal effects on dermatophytes, candida, yeast and cryptococcus...
