xWhat Is Atenolol Tablets 100mg?
Atenolol Tablets 100mg contain Atenolol 100mg, a cardioselective beta-blocker made by Zafa Pharmaceutical Laboratories, Pakistan. It is used for high blood pressure, angina and irregular heart rhythms. This medicine requires a prescription.
How It Works
Atenolol blocks beta-1 receptors in the heart, slowing the heart rate and reducing the force of contraction. This lowers blood pressure and the heart's oxygen demand, preventing angina.
Uses
- Hypertension
- Angina pectoris
- Certain heart rhythm disturbances (arrhythmias)
- Early treatment after a heart attack, as directed
Dosage
Usually 50mg to 100mg once daily, as prescribed; 100mg is a common maximum for blood pressure and angina. Lower doses are used in kidney impairment. Take at the same time each day. Do not stop suddenly, as this can worsen angina or trigger a heart attack; your doctor will reduce the dose gradually.
Side Effects
Tiredness, cold hands and feet, slow heartbeat, dizziness, stomach upset, sleep disturbance and, occasionally, erectile problems or worsening breathlessness.
Precautions
Not for people with asthma, very slow heart rate, heart block, uncontrolled heart failure, severe circulation problems or untreated phaeochromocytoma. It can mask signs of low blood sugar in diabetes and of an overactive thyroid. Caution with verapamil, diltiazem and some antiarrhythmics. Store below 30°C.
