Additional Details

Combined intravenously with imipenem in order to protect it from dehydropeptidase and prolong its antibacterial effect.
Cilastatin is a chemical compound which inhibits the human enzyme dehydropeptidase. Dehydropeptidase is found in the kidney and is responsible for degrading the antibiotic imipenem. Cilastatin is therefore combined intravenously with imipenem in order to protect it from dehydropeptidase and prolong its antibacterial effect. However, cilastatin in and of itself does not have any antibacterial activity.
Mode of Action:
Cilastatin is a specific and reversible renal dehydropeptidase-I inhibitor. Since the antibiotic, imipenem, is hydrolyzed by dehydropeptidase-I, which resides in the brush border of the renal tubule, cilastatin is administered with imipenem to block the metabolism and thus the inactivation of imipenem so that antibacterial levels of imipenem can be attained in the urine. The drug also prevents the metabolism of leukotriene D4 to leukotriene E4 through the inhibition of leukotriene D4 dipeptidase.
