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 avaliable 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 maybe okay.[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.[3] It is avaliable as a generic medication.[1] A month supply in the United States costs about 1.32 USD per month as of 2019.[4] In 2016 it was the 105th most prescribed medication in the United States with more than 7 million prescriptions.[5]

Medical uses[edit]

It is useful for high blood pressure, heart failure, and diabetic kidney disease.[1] It is a reasonable initial treatment for high blood pressure.[1] Other reasonable initial options include angiotensin II receptor antagonists, calcium-channel blockers, and thiazide diuretics.[1]

Side effects[edit]

The most common side effects patients experience are a headache or a chronic cough. The chronic cough develops in about 20% of patients treated,[6] and those patients that experience it find it develops after a few months of use. Anaphylaxis, angioedema, and elevation of potassium levels are more serious side effects that can also occur.

Contraindications[edit]

Benazepril should be discontinued during pregnancy, as it can harm the fetus.

Dosage forms[edit]

It is also available in combination with hydrochlorothiazide, under the trade name Lotensin HCT', and with amlodipine (trade name Lotrel).

Veterinary use[edit]

Under the brand names Fortekor (Novartis) and VetACE (Jurox Animal Health),[citation needed] benazepril hydrochloride is used to treat congestive heart failure in dogs[7][8] and chronic kidney failure in cats and dogs.[citation needed]
