Tenoclor 50 mg Tablet

Atenolol and chlorthalidone have been used singly and concomitantly for the treatment of hypertension. Studies have shown that there is no interference with bioavailability when these agents are given together in the single combination tablet. Therefore, this combination provides a convenient formulation for the concomitant administration of these two drugs. Atenolol is a beta1-selective (cardioselective) beta-adrenergic receptor blocking agent that provides- reduction in resting and exercise heart rates and cardiac output reduction of systolic and diastolic blood pressure at rest and on exercise reduction in reflex orthostatic tachycardia. Chlorthalidone is a monosulfonamyl diuretic with prolonged action and low toxicity. It produces diuresis with greatly increased excretion of sodium and chloride at distal convoluted tubule of the nephron.
