What Is Nifedipine ER 90mg?
Nifedipine ER is an extended-release calcium channel blocker, also known by the brand name Procardia XL. It works by relaxing blood vessels so the heart does not have to pump as hard, which lowers blood pressure and improves blood flow to the heart. Doctors prescribe nifedipine ER to manage hypertension and to help prevent angina (chest pain) caused by coronary artery spasm or chronic stable angina. The extended-release tablet is taken once daily and releases medication gradually over 24 hours.
