CARDIOLITE 100 MG TABLET

Atenolol 100mg Tablet primarily works by selectively blocking beta-1 adrenergic receptors in the heart, which are responsible for the effects of catecholamines like norepinephrine and epinephrine. This blockage reduces cardiac output by decreasing heart rate and myocardial contractility. As a result, the heart beats more slowly and with less force, leading to a reduction in blood pressure. By blocking these receptors, Atenolol inhibits the sympathetic nervous system's stimulation of the heart, thereby lowering the heart's oxygen demand and reducing the risk of angina. This mechanism of action helps in the management of hypertension and certain cardiovascular conditions by promoting a more efficient and controlled cardiac function.
