Abstract

The invention discloses a cefpodoxime proxetil dispersible tablet which comprises the following raw materials in percentage by weight: 20-45 percent of cefpodoxime proxetil, 30-50 percent of filler, 5-15 percent of a disintegrating agent, 0.25-1.0 percent of a wetting agent, 0.25-1.5 percent of a flavoring agent and 5.0-15 percent of polyethylene glycol 200. The preparation method adopts a specific wetting agent, so as to improve mobility, dissolubility and uniformity in mixing of the product and facilitate the storage of the product, and after the product is stored for a period of time, no obvious changes occur. According to the invention, the cefpodoxime proxetil dispersible tablet is obtained through direct powder mixing, granulation and tabletting, and the preparation method is simple without any special equipment, and is suitable for industrial production.

Description

technical field [0001] The invention relates to the field of pharmaceutical preparations, in particular to a cefpodoxime axetil dispersible tablet and a preparation method thereof. Background technique [0002] Cefpodoxime axetil is the third-generation oral broad-spectrum cephalosporin, which is hydrolyzed into cefpodoxime on the intestinal wall after oral administration and absorbed by the intestinal tract. Cefpodoxime has a broad-spectrum and powerful antibacterial effect and a long half-life, and is widely used in the treatment of respiratory tract, urinary tract, obstetrics and gynecology infectious diseases and suppurative otitis media. [0003] Cefpodoxime Proxetil (CPDX-PR) is the third-generation oral cephalosporin [0004] It was listed in Japan for the first time in 1990. Its structural feature is that the 7th position of the cephalosporin skeleton is connected with a methoxyiminothiazolyl group, the 3rd position is connected with a methoxymethyl group, and the 4...
