Abstract

The invention provides a meropenem medicinal composition for injection and a preparation method thereof. The medicinal composition consists of meropenem and disodium hydrogen phosphate, wherein 1000 pieces of the medicinal composition are prepared from 500 to 1,000g of the meropenem, and 250 to 500g of disodium hydrogen phosphate. The preparation method of the medicinal composition comprises the following steps: rechecking whether the meropenem and disodium hydrogen phosphate are in accordance with the requirements of asepsis and granularity for later use; performing asepsis treatment on an antibiotic bottle and an operation vessel, standing after the moisture of the antibiotic bottle is qualified; mixing; filling; plugging; screwing a cover; testing by use of a lamp; and packaging and sending into a warehouse. The meropenem medicinal composition has simple prescription and excellent stability, and is suitable for long-term storage and industrial large-scale production.

Description

technical field [0001] The invention relates to the field of medicine, in particular to a meropenem pharmaceutical composition for injection and a preparation method thereof. Background technique [0002] Meropenem is a variety developed by Sumitomo Co., Ltd. of Japan. It was launched in January 1995 under the trade name "Merrem" (美平), and it was jointly developed with AstraZeneca Pharmaceuticals. It was first launched in June 1996. Due to the carbapenem with a methyl group in the first position of the chemical structure of meropenem, it is stable to renal dehydropeptidase and does not need to be combined with enzyme inhibitors. The antibacterial spectrum and antibacterial effect are similar to imipenem, and have certain post-antibiotic effects. Meropenem is a very broad range of injectable antibiotics used to treat a number of different infections, including meningitis and pneumonia. It is a beta-lactam antibiotic that falls under the class of carbapenems. Unlike subampe...
