WebAbstract. The carbapenems are beta-lactam antimicrobial agents with an exceptionally broad spectrum of activity. Older carbapenems, such as imipenem, were often susceptible to degradation by the enzyme dehydropeptidase-1 (DHP-1) located in renal tubules and required co-administration with a DHP-1 inhibitor such as cilastatin. WebJul 17, 2024 · Cilastatin limits the renal metabolism of imipenem and does not have antibacterial activity. The bactericidal activity of imipenem results from binding to PBP 2 and PBP 1B in Enterobacteriaceae and Pseudomonas aeruginosa and the subsequent inhibition of penicillin binding proteins (PBPs). WebCilastatin is used for treating diseases caused by polyresistant Gram-negative microorganisms and serious complex infections, including infection of S. aureus. Because of its strong activity against anaerobic bacteria, cilastatin is effective in monotherapy of intraabdominal infections. sample cleaning company flyers
