Pregnancy-Lactation

Pregnancy Available data from a small number of postmarketing cases in pregnancy are not sufficient to identify any drug-associated risks for major birth defects, miscarriage, or adverse maternal or fetal outcomes Animal data Developmental toxicity studies with imipenem and cilastatin sodium (alone or in combination) administered to mice, rats, rabbits, and monkeys at doses 0.4 to 2.9 times the recommended human dose (RHD), (based on body surface area), showed no drug-induced fetal malformations Embryofetal development studies with imipenem/cilastatin administered to cynomolgus monkeys at doses similar to RHD (based on body surface area) showed an increase in embryonic loss Lactation There are insufficient data on presence of imipenem/cilastatin in human milk, and no data on effects on breastfed child, or on milk production; developmental and health benefits of breastfeeding should be considered along with mother’s clinical need for therapy and any potential adverse effects on breastfed child from therapy or from the underlying maternal condition

Mode of Action

Imipenem is a potent inhibitor of bacterial cell wall synthesis and is bactericidal against a broad spectrum of pathogens. It is resistant to degradation by bacterial beta-lactamases. 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.
