Problems solved by technology

[0007] 1) easy to leak
After the common preparation is used, it is easy to leak out under the action of vaginal secretions and excretions. On the one hand, the drug will be lost and the curative effect cannot be guaranteed. Finally, the lying position is adopted, which brings great inconvenience to the patient and reduces the patient's compliance with medication.
[0008] 2) frequent use of medication
Due to the problems of leakage and fast drug release, the drug has a short action time in the vagina and low curative effect. Therefore, in most cases, it needs to be used once a day for 7 to 10 consecutive days, and the frequency of administration is frequent.
Frequent and multiple medications lead to poor drug compliance of patients, and some even cannot guarantee to complete the entire course of treatment, which affects the curative effect

Abstract

The invention relates to a medicinal composition for vagina. The composition comprises butoconazole nitrate, poloxamer, hydroxypropyl methylcellulose, Carbomer and other additives. The composition has the characteristics of good vagina mucosa adhesion and long-acting slow release, and in vivo and in vitro experiment results prove that the composition can continuously release the medicament for more than 72 hours.

Description

technical field [0001] The invention relates to the technical field of pharmaceutical preparations, in particular to a vaginal pharmaceutical composition. Background technique [0002] Gynecological inflammation is a common disease in women. About 87% of adult women in the world have been infected with gynecological inflammation to varying degrees. Common clinical gynecological inflammations include vaginitis, cervicitis, pelvic inflammatory disease, endometritis, etc. Among them, the incidence of vaginitis The highest, accounting for about one-third of gynecological inflammation. Vaginitis is mainly divided into fungal vaginitis, bacterial vaginosis, and trichomonas vaginitis, among which the incidence of bacterial vaginosis and fungal vaginitis is relatively high. With the improvement of living standards, the incidence of trichomonas vaginitis Greatly reduced. Mycotic vaginitis is mainly caused by Candida, so it is also called Candida vaginitis. According to statistics, ...
