Tenormin Tablet 100mg

About Tenormin Tablet 100mg

Tenormin Tablet Uses

• High blood pressure (hypertension)
• Angina (chest pain due to reduced blood flow to the heart)
• Irregular heartbeat (certain arrhythmias)
• Secondary prevention after a heart attack
• Migraine prevention, used off label in some cases

Tenormin Tablet Benefits

• This tablet lowers blood pressure by reducing heart rate and workload.
• This tablet reduces chest pain frequency in patients with angina.
• Once daily dosing supports better treatment adherence.
• This tablet lowers the risk of future cardiac events after a heart attack.
• Mainly targets the heart, causing fewer lung related side effects than older beta blockers.

What Experts Say

Cardioselective beta blockers like atenolol are widely used by Pakistani physicians to manage high blood pressure and angina, especially in patients who also have a fast resting heart rate. Atenolol works mainly on beta-1 receptors in the heart, slowing the heart rate and reducing the force of each contraction, which lowers the overall workload on the heart.

Because atenolol acts mostly on the heart rather than the lungs, physicians in Pakistan often favor it over older non-selective beta blockers for patients who also need blood pressure control but do not have significant lung disease. It is also commonly continued after a heart attack to reduce the risk of future cardiac events.

Sudden discontinuation of atenolol can trigger a rebound rise in blood pressure and heart rate, so Pakistani physicians typically taper the dose gradually rather than stopping it abruptly. Regular monitoring of pulse rate and blood pressure helps guide dose adjustments, particularly in older patients or those with kidney impairment.
