Nifedipine is a calcium channel blocker. It works by affecting the movement of calcium into the cells of the heart and blood vessels. As a result, nifedipine relaxes blood vessels and increases the supply of blood and oxygen to the heart while reducing its workload. Taylor RJ. Pharmaceutical Division, Miles Inc.

Some medical conditions may interact with Procardia XL sustained-release tablets. Some studies have shown that nifedipine may increase hepatic portal venous hypertension, which may be important in patients with severe liver disease. Frequent monitoring of liver function tests during nifedipine therapy is recommended in patients with underlying liver disease. Schwartz JB, Migliore PJ. Effect of nifedipine on serum digoxin concentration and renal digoxin clearance. Clin Pharmacol Ther. Procardia dilates the main coronary arteries and coronary arterioles, both in normal and ischemic regions, and is a potent inhibitor of coronary artery spasm, whether spontaneous or ergonovine-induced. This property increases myocardial oxygen delivery in patients with coronary artery spasm, and is responsible for the effectiveness of Procardia in vasospastic Prinzmetal's or variant angina. Whether this effect plays any role in classical angina is not clear, but studies of exercise tolerance have not shown an increase in the maximum exercise rate-pressure product, a widely accepted measure of oxygen utilization. This suggests that, in general, relief of spasm or dilation of coronary arteries is not an important factor in classical angina. Recommended follow-up care after UFE includes a checkup 1 to 3 weeks afterward and an or 3 to 6 months later. The Israeli Sprint Study Group. Secondary Prevention Reinfarction Israeli Nifedipine Trial SPRINT: a randomized intervention trial of nifedipine in patients with acute myocardial infarction.

For patients who do not respond adequately over a 12-week escalation period, increasing the PROCRIT dose further is unlikely to improve response and may increase risks.

IV injections should be given slowly over at least 1 to 2 minutes. IV infusions should be diluted in at least 50 mL of suitable diluent and administered over at least 15 minutes.
