Abstract

The invention belongs to the technical field of pharmaceutical preparations and discloses a pharmaceutical preparation of a tebipenem pivoxil composition and a preparation method of the pharmaceutical preparation. The pharmaceutical preparation of the tebipenem pivoxil composition comprises the following components in parts by weight: 10-100 parts of tebipenem pivoxil, 10-100 parts of a resin material, 200-1000 parts of a substrate material, 200-1000 parts of a filler, 1-10 parts of a defoamer, 1-10 parts of a surfactant, 10-100 parts of a lubricant and 20-100 parts of a binder. The pharmaceutical preparation of the tebipenem pivoxil composition has good dissolution rate and stability and also covers the bad taste of tebipenem pivoxil, and has a good taste. The preparation method provided by the invention further improve the dissolution rate of medicines, and the bitterness caused by tebipenem pivoxil is effectively covered, the effectiveness and safety of the preparation are guaranteed and the medicament compliance of the patient is improved.

Description

technical field [0001] The invention belongs to the technical field of pharmaceutical preparations, in particular to a pharmaceutical preparation of a tibipenem compound and a preparation method thereof. Background technique [0002] Tibipenem is a carbapenem antibiotic developed by Pfizer of the United States, and its chemical name is (1R,5S,6S)-1-methyl-6-[(1R)-1-hydroxyethyl ]-2-[1-(1,3-Thiazolin-2-yl)azetidin-3-yl]thio-1-carbapenicillin-2-ene-3-carboxylic acid methyl pivalate , which has a structure as shown in formula I: [0003] [0004] Tibipenem has a broad antibacterial spectrum and has strong antibacterial activity against both Gram-positive and Gram-negative bacteria, such as Staphylococcus, Streptococcus, Pneumococcus, Moraxella catarrhalis, and Influenza bacteria; Moreover, it has a stronger antibacterial effect on most clinically isolated strains than penicillin series and cephalosporin series. The study also found that tibipenem has a low inhibitory conc...
