ABSTRACT
Hypertension is common medical problem encountered during pregnancy. However medication administered for maternal hypertension may cause fetal or neonatal complications. Angiotensin converting enzyme inhibitor or angiotensin II receptor blocker are rarely used during pregnancy, and there are few reports about the effect of them, because administration of these drugs during pregnancy may cause oligohydramnios, renal tubular dysplasia, hypocalvaria, pulmonary hypoplasia, intrauterine growth retardation, neonatal anuria and persistent ductus arteriosus. We report a case of neonatal acute renal failure by angiotensin II receptor blocker during pregnancy. In this case, the neonate with meconium aspiration was admitted to neonatal intensive care unit (NICU). During the NICU stay, neonatal anuria occurred, and there was a medical history that his mother took Candesartan Cilexeril (Atacand(R)), one of angiotensin II receptor blockers during pregnancy. The neonate showed intrinsic acute renal failure, so fluid was restricted and diuretics were administered to the neonate, and after 10 days, anuria improved.
