Aten-H 25 Tablet combines Atenolol and Hydrochlorothiazide to control high blood pressure when one medicine alone is not enough. Lowering blood pressure this way also helps cut the future risk of heart attack and stroke. Atenolol slows the heart and reduces the force of each beat, while Hydrochlorothiazide removes extra water and salt through the kidneys. Together, they bring blood pressure down and keep it steadier over time when taken regularly as prescribed.

How Does It Work?
Atenolol is a beta-blocker that acts on the heart to slow the pulse and lessen the force of contraction. Hydrochlorothiazide is a diuretic that increases urine output, clearing surplus water and certain salts. The combined effect lowers blood pressure and improves overall circulation.
