Calcibloc Indication

For the management of vasospastic angina, chronic stable angina and hypertension.

Calcibloc Pharmacology

Nifedipine, the prototype of the dihydropyridine class of calcium-channel antagonists, is similar to other dihydropyridines including amlodipine, felodipine, isradipine, and nicardipine. Nifedipine is used to treat Prinzmetal's angina, hypertension, and other vascular disorders such as Raynaud's phenomenon. By blocking the calcium channels, Nifedipine inhibits the spasm of the coronary artery and dilates the systemic arteries, results in a increase of myocardial oxygen supply and a decrease in systemic blood pressure.

Calcibloc Absorption

Rapidly and fully absorbed following oral administration.
