Plendil (Felodipine)

Plendil is used to treat high blood pressure (hypertension). Lowering high blood pressure helps prevent strokes, heart attacks, and kidney problems. Felodipine is known as a calcium channel blocker. By blocking calcium, this medication relaxes and widens blood vessels so blood can flow more easily.

Plendil is an oral calcium- channel blocker (CCB) of the dihydropyridine (DHP) class. Other calcium channel blockers in the DHP class include nifedipine (Procardia, Adalat), amlodipine (Norvasc), nisoldipine (Sular), nicardipine (Cardene), and isradipine (Dynacirc). Calcium is necessary for muscle cells to contract. Plendil prevents calcium from being released within the muscle cells of the small arteries and thereby causes the muscles to relax and the arteries to dilate or expand. Plendil has little or no effect on the muscles of veins or the heart . Plendil was approved by the FDA in 1991.
