Zafnol Tablet

About Zafnol Tablet

Zafnol tablet uses include treating hypertension, angina pectoris, cardiac arrhythmias, and preventing cardiovascular events after a heart attack. It contains Atenolol, a cardioselective beta-blocker that works by selectively blocking beta-1 receptors in the heart. This action slows down the heart rate, reduces the force of heart contractions, and decreases blood pressure.
