Mechanism of Action

• Atenolol is a Beta-1 Selective Blocker.

• Blocks beta-adrenergic receptors in the heart → slows heart rate and reduces contractility.

• Decreases cardiac output → lowers blood pressure.

• Reduces oxygen demand of the heart → relieves angina.

• Stabilizes abnormal heart rhythms.

• 25 mg once daily is a common starting dose for hypertension and angina.

• Take with water, preferably at the same time daily.

• Do not stop suddenly – may cause rebound hypertension or angina.
