What is Atlin?

Atlin (Atenolol) is a cardioselective beta-blocking drug. It probably act by reducing cardiac rate and contractility, which makes it effective in eliminating or reducing the symptoms of patients with angina. As with other beta-blockers, its mode of action in the treatment of hypertension is unclear.

Atlin (atenolol) is not recommended for children. Keep it out of the reach of children.

Atenolol is without ISA (Intrinsic Sympathomimetic Activity) and MSA (Membrane Stabilizing Activity), and has negative inotropic effect. Atenolol is effective for atleast 24 hours after a single oral daily dose. The simplicity of dosing facilitates compliance by its acceptability to patients.


Atlin (Atenolol) is indicated for Hypertension, Angina Pectoris, and oral maintenance dosage for Arrythrriias after having controlled with i.v. Atenolol is also recommended for long term prophylaxis of Myocardial Infarction.

Dosage and Administration

Most patients respond to 50-100mg daily given orally as a single oral dose. The effect will be fully established in 1-2 weeks. A further reduction in blood pressure may be achieved by combining with other antihypertensive drugs specially diuretics.

Most patients with angina will respond to 100mg daily as a single dose or 50mg given twice daily.

Having controlled arrythmias with i.v. Atenolol, a suitable oral maintenance dosage is 50-100mg daily, given as a single dose.
