Tenoclor 50 Tablet contains two active ingredients:

Atenolol (50 mg): This beta-1 selective adrenergic receptor blocker works by slowing down the heart rate and reducing the workload on the heart. By blocking the action of certain natural body chemicals like epinephrine on the heart and blood vessels, atenolol helps to lower blood pressure.
Chlorthalidone (12.5 mg): As a thiazide-like diuretic, chlorthalidone increases the amount of urine produced, thereby reducing fluid volume in the blood vessels. It aids the kidneys in eliminating sodium and water, which decreases extracellular fluid volume and plasma volume, consequently lowering blood pressure.

Pregnancy

Caution is advised while taking Tenoclor 50 Tablet if you are pregnant. It is best to consult your doctor before taking this medicine.

Breastfeeding

If you are breastfeeding, please discuss this with your doctor before starting Tenoclor 50 Tablet.
