Problems solved by technology

The document whose application number is 200410010643.0 discloses a medicine for treating bacterial vaginosis and its preparation method, wherein polyethylene glycol 400 is used as a soft capsule filler, but due to the difference in the molecular weight of polyethylene glycol, it is selectively absorbed in the capsule shell Moisture is also different, resulting in different hardening of the capsule shell, which affects the rate of drug release
Also, low molecular weight polyethylene glycols are the most toxic

Abstract

The invention refers to a chloramphenicol vaginal soft capsule. The content of the soft capsule is composed of the following components by weight proportion: 50-200g of chloramphenicol; 140-560g of 1.2-propylene glycol and 60-240g of polyethelene glycol 600; the formula of gelatin liquid is that gelatin: glycerol: water is equal to 0.5-1.5:0.4-0.6:0.5-1.5; the preparation method and the formula are scientific and precise, and the dosage form is novel. Compared with suppository, the soft capsule is characterized by higher bioavailability, accurate content, good uniformity and beautiful appearance, which is especially applied to the treatment of bacterial vaginitis, trichomonal vaginitis, colpitis mycotica and senile vaginitis.

Description

technical field [0001] The invention relates to the field of external medicines for treating vaginitis, in particular to chloramphenicol soft capsules. Background technique [0002] Vaginitis is an inflammation of the vaginal mucosa and submucosal connective tissue, and is a common disease in gynecological clinics. [0003] The most effective drugs for treating bacterial vaginosis are mostly metronidazole or tinidazole, which are sensitive to most anaerobic bacteria in the vagina, and reduce the pH of the vagina to inhibit the growth and reproduction of Gardnerella vaginalis. However, studies have shown that: chloramphenicol has a broad-spectrum antibacterial effect, and its effect on gram-negative bacilli such as influenza bacillus and Salmonella is stronger than that of gram-positive bacteria such as staphylococcus; chloramphenicol is still effective against anaerobic bacteria, including fragile Bacteroides, etc. are also effective; it also has antimicrobial effects on Ch...
