Meropenem is an ultra-broad-spectrum injectable antibiotic used to treat a wide variety of infections. It is a β-lactam and belongs to the subgroup of carbapenem, similar to imipenem and ertapenem. Meropenem was originally developed by Dainippon Sumitomo Pharma. It gained US FDA approval in July 1996. It penetrates well into many tissues and body fluids, including cerebrospinal fluid, bile, heart valve, lung, and peritoneal fluid. It was initially marketed by AstraZeneca under the trade name Merrem.
Mechanism of action
Meropenem is bactericidal except against Listeria monocytogenes, where it is bacteriostatic. It inhibits bacterial wall synthesis like other β-lactam antibiotics. In contrast to other beta-lactams, it is highly resistant to degradation by β-lactamases or cephalosporinases. In general, resistance arises due to mutations in penicillin-binding proteins, production of metallo-β-lactamases, or resistance to diffusion across the bacterial outer membrane. Unlike imipenem, it is stable to dehydropeptidase-1, so can be given without cilastatin.
