What is this medication for?
Nifedipine belongs to the class of medications called calcium channel blockers. It is used to treat high blood pressure and angina (chest pain brought on by exercise or stress). It works to control blood pressure and reduce the number of angina attacks by relaxing blood vessels so that the heart does not have to pump as hard.
