Pharmacological action Efoksa

Efoksa is an organic nitrate, the therapeutic effect of the reception which is distributed primarily on the venous vessels. Effect of the drug is directed to the stimulation of nitric oxide in the endothelium of blood vessels. In turn, nitric oxide contributes to the activation of intracellular guanylate cyclase, thereby increasing cGMP.

Efoksa able to reduce preload and afterload on the myocardium, thereby reducing its need for oxygen. Also, the drug has the ability to provide koronarorasshiryayuschee action.

Use Efoksa leads to a decrease in blood flow to the right atrium, resulting in marked regression of symptoms of pulmonary edema and reduced the pressure in the pulmonary circulation. Furthermore, the use Efoksa positive effect on the course of coronary blood flow distribution in the areas with reduced blood circulation.

During the reception Efoksa there is an increase in exercise tolerance in patients with angina and coronary artery disease, vasodilation hard shell GM (may cause pain reactions).

For drug tolerance develops, but after its cancellation or interruption of treatment sensitivity Efoksa soon restored.
