Benazepril, sold under the brand name Lotensin among others, is a medication used to treat high blood pressure, heart failure, and diabetic kidney disease.[1] It is a reasonable initial treatment for high blood pressure.[1] It is taken by mouth.[1] Versions are available as the combinations benazepril/hydrochlorothiazide and benazepril/amlodipine.[1]
Common side effects include feeling tired, dizziness, cough, and light-headedness with standing.[1] Serious side effects may include kidney problems, low blood pressure, high blood potassium, and angioedema.[1] Use in pregnancy may harm the baby, while use when breastfeeding may be safe.[2] It is an ACE inhibitor and works by decreasing renin-angiotensin-aldosterone system activity.[1]
Benazepril was patented in 1981 and came into medical use in 1990. It is available as a generic medication.[1] In 2023, it was the 172nd most commonly prescribed medication in the United States, with more than 2 million prescriptions.[3][4]
