Amlodipine is an antihypertensive medication that is widely used to treat high blood pressure and chest pain. There are several synonyms for amlodipine, which are other brand names or generic names for the same active ingredient. Some commonly used synonyms for amlodipine include Norvasc, Istin, Amlokind, Amlozaar, Amlode, Amlowin, and Amlode-AT. These medications work in the same way as amlodipine, reducing blood pressure and improving blood flow to the heart.
