商品名：Adalat and Procardia
Calcium-channel blocking drug of the dihydropyridine class. Vasodilator. The action of nifedipine is similar to other calcium-channel blocking drugs, such as amlodipine. They block voltage-dependent calcium entry into smooth muscle cells. Drugs of the dihydropyridine class are more specific for vascular smooth muscle than the cardiac tissue. Therefore, they have less effect on cardiac conduction than diltiazem.
Nifedipine is used for smooth muscle relaxation and to induce vasodilation. It is indicated for treatment of systemic hypertension. Use in animals is rare because there is more experience with amlodipine. The use of nifedipine in animals has been primarily derived from empirical use. There are no well-controlled clinical studies or efficacy trials to document clinical effectiveness.
