Mode of Action
Atenolol is a beta-blocker that acts preferentially on the ?1 adrenergic receptors in the heart. Chlorthalidone is a thiazide-like diuretic that reduces BP possibly by inhibiting sodium reabsorption at the beginning of the distal convulated tubule. Combination of the two drugs results in additive antihypertensive action.
