Abstract

A fibrauretine gel preparation and a preparation method thereof are provided. The preparation contains 0.25-5wt% of fibrauretine, 0.5-5wt% of gel matrix, 0.01-1wt% of pH regulator, 0.05-0.15wt% of antiseptics and distilled water in balance. The preparation method doesn't use any stabilizer and employs heating process to completely swell the gel substrate during a short period of time. The production cycle is short and suitable for industrialized production. The fibrauretine gel has uniform and fine texture and good effect of coupling and hydration to mucosa, and also has the advantages of remarkable curative effect, convenient adminstraiton, long retention time in vagina, long-lasting action, complete release of active components, no foreign body sensation of vagina, no damage to vagina, no deformation, storage stability and no contamination to clothing.

Description

technical field [0001] The invention relates to a pharmaceutical preparation and a method thereof, in particular to a palmatine gel preparation and a preparation process thereof. Background technique [0002] The chemical name of palmitine hydrochloride is palmitine hydrochloride, and its molecular formula is C21H21NO4·HCl·3H2O. It is an effective anti-infection drug, has obvious antibacterial effect on Gram-positive and negative bacteria, and has obvious inhibitory effect on various fungi, and has different degrees of inhibitory effect on mycoplasma, chlamydia and mold. Palmatine is widely used in clinical practice. Gynecology is mainly used in acute and chronic adnexitis, acute and chronic pelvic inflammatory disease, acute and chronic cervicitis, acute and chronic endometritis, vulvitis, acute and chronic vaginitis, fungal vaginitis, postpartum infection Wait. [0003] According to the pharmacological effects of palmatine, it has a unique role and effect in the treatmen...
