Product Description

Tenormin is a medical product of the new generation which is used for the treatment of the diseases of the cardiovascular system. It contains the active ingredient Atenolol – cardioselective beta1-adrenoreceptor.

The modern cardiology can hardly do without beta1-adrenoreceptors. These are medicines which have a broad spectrum of possibilities and maintain functions of the cardiovascular system regardless of the type of the disease.

Tenormin provides a strong hypotensive, antianginal, and antiarrhythmic action, reduces the contractile function of myocardium and stabilizes the blood pressure within 24 hours after the use.

Tenormin differs from non-selective beta-adrenoreceptors because it does not affect the systems and organs which contain β2-adrenoreceptors (Pancreas, skeletal muscles, smooth muscles, bronchial tubes, uterus).
