About Cilastatin Enzyme inhibitor Antibiotic resistance reducer to imipenem Mechanism of Action of Cilastatin Cilastatin is an inhibitor of dehydropeptidase I an enzyme found in the brush border of the renal tubules. It is given as the sodium salt with imipenem to prevent its renal metabolism and protect against nephrotoxic effects Imipenem Description Semisynthetic thienamycin that has a wide spectrum of antibacterial activity against gram-negative and gram-positive aerobic and anaerobic bacteria including many multiresistant strains. It is stable to beta-lactamases. Mechanism of action Imipenem acts as an antimicrobial through the inhibition of cell wall synthesis of various gram-positive and gram-negative bacteria. This inhibition of cell wall synthesis in gram-negative bateria is attained by binding to pencillin binding proteins (PBPs). In E. coli and selected strains of P. aeruginosa imipenem has shown to have the highest affinity to PBP-2 PBP-1a and PBP-1b.
