What is Procardia?
Nifedipine (brand names Adalat CC and Procardia, according to FDA Orange Book) is a dihydropyridine calcium channel blocker that primarily blocks L-type calcium channels. Its main uses are as an antianginal (especially in Prinzmetal's angina) and antihypertensive, although a large number of other indications have recently been found for this agent, such as Raynaud's phenomenon, premature labor, and painful spasms of the esophagus such as in cancer and tetanus patients. It is also commonly used for the small subset of pulmonary hypertension patients whose symptoms respond to calcium channel blockers. It is on the World Health Organization's List of Essential Medicines, a list of the most important medication needed in a basic health system.
