The medicine is aimed at treating hypertension. It is also prescribed for patients with coronary heart disease and chronic heart failure.

Product Description

The medicine is a selective adrenoreceptor blocking agent. It has no pronounced characteristics that would block the membranes. It is almost unlike beta receptors with smooth muscles and with receptors that do not participate in the regulation of metabolism. The tablets do not affect the respiratory resistance and metabolic effects. The selectiveness of the drug component extends beyond its dose range. The tablets have no negative inotropic effect.

The maximum result may be achieved in three to four hours after taking the pills. The components of the remedy are eliminated from the body after 10-12 hours. It falls into disuse from the body for a half and this leads to the fact that it is effective 24 hours after taking. The cure is not effective immediately and its maximum effect is achieved after two weeks of administration.

In case if the therapy is intensive, the patients who have ischemic heart disease and who do not have chronic heart failure may take pills to reduce the cardiac output and the myocardial need in oxygen. This is achieved by reducing the stroke volume. If the therapy lasts for a long time, the high peripheral resistance will be not so strong. There is a mechanism that reduces the activity of renin in plasma is the heart of beta blockers.
