Amlodipine/benazepril, marketed as Lotrel among others, is a medication used to treat high blood pressure.[1] It is a combination of amlodipine, a calcium channel blocker and benazepril, an angiotensin converting enzyme inhibitor.[1] It may be used if a single agent is not sufficient.[1] It is taken by mouth.[1]

Common side effects include cough, dizziness, and swelling.[1] Serious side effects may include angioedema, myocardial infarction, high blood potassium, liver problems, and low blood pressure.[1] Use in pregnancy is not recommended.[1] Amlodipine works by increasing the size of arteries while benazepril works by decreasing renin-angiotensin-aldosterone system activity.[1]

The combination was approved for medical use in the United States in 1995.[2] It is available as a generic medication.[3] A month supply in the United States has a wholesale cost of about US$4.50.[4] In 2017, it was the 160th most commonly prescribed medication in the United States, with more than three million prescriptions.[5][6]
