Adalat, which is nifedipine - belongs to hypotensive medicine with antianginalny activity. Blocking calcic channels, an active component of Adalat (nifedipine) causes decrease in intracellular concentration of ions of calcium in smooth muscle cell of intima of vessels and cardiocyte, causing vasodilatory action - in particular, on coronary vessels. As a result of decreases systolic blood pressure, falls TPR and decreases afterload on cardiac muscle. Except for normalization of a coronary blood flow, Adalat promotes pressure decrease in system of pulmonary artery, improves cerebral haemo dynamics. Long-term taking of medicine guarantees anti-atherogenous action, prevents thrombocyte aggregation.
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.
