Tenormin Dosage Forms

This drug is available in Tenormin 25 mg, 50 mg, and 100 mg tablets.

Tenormin Mechanism of Action

This beta1-selective beta-adrenergic receptor blocking agent primarily works by blocking the action of the endogenous catecholamines, norepinephrine, and epinephrine. It hampers the reaction to beta-adrenergic stimulation but has little to no effect on beta2 receptors.

This action decreases heart rate, the strain on the heart, and blood pressure. It effectively relaxes the blood vessels and blocks adrenaline and noradrenaline impulses in the heart.

How to Take Tenormin

Before starting your treatment using Tenormin, it is important to read the patient information leaflet. You must not take Atenolol or other medications unless you fully understand the uses and directions. Ask your physician or pharmacist for further medical advice or information while on this medication.
