A beta-blocker that slows down the heart rate and reduces blood pressure.
A thiazide diuretic that increases urine production, lowering blood volume and blood pressure.
Treatment of hypertension (high blood pressure)
Treatment of angina pectoris (chest pain)
Atenolol blocks the effects of adrenaline on the heart, reducing heart rate and contractility. Hydrochlorothiazide increases the excretion of sodium and water from the body, reducing blood volume and subsequently blood pressure. The combination provides a synergistic effect, lowering blood pressure more effectively than either drug alone.
