Verapamil is a calcium channel blocker, it treats high blood pressure relaxing and widening blood vessels.

Pharmacological influence of Calan is explained by braking of a flow of calcium ions through the slowed-down calcic tubules of cellular covers of smooth muscle structure of vessels and a cardiac muscle. Calan is prescribed if it was diagnosed paroxysmal supraventricular tachycardia (except WPW syndrome), sinus tachycardia, premature atrial contraction, blinking and atrial flutter, stenocardia (inc. stress, postinfarction), arterial hypertension, hypertensive crisis, idiopathic hypertrophic subaortic stenosis, hypertrophic cardiomyopathy.

Isoptin is a calcium ion antagonist of the phenylalkylamine group. It improves myocardial perfusion, eliminates coronary spasm, reduces myocardial oxygen demand. It is used for diseases of the cardiovascular system.

BCCC; a derivative of diphenylalkylamine. Has antianginal, anti-arrhythmic and hypotensive effect. The antianginal effect is associated with both direct action on the myocardium and with the effect on peripheral hemodynamics. It is prescribed with stenocardia, supraventricular tachycardia, sinus tachycardia, ciliary tachyarrhythmia, atrial flutter, atrial extrasystole, arterial hypertension, GOKMP, primary hypertension in the "small" circle of the circulation.
