Zafnol 50mg Tablets (20’s) – Atenolol | Beta-Blocker for High Blood Pressure, Chest Pain & Heart Protection

Description

Zafnol 50mg Tablets contain Atenolol, a cardio-selective beta-blocker that lowers blood pressure and reduces the workload on the heart. It helps control hypertension (high blood pressure), prevents chest pain (angina), manages certain irregular heartbeats (arrhythmias), and protects the heart after a heart attack.
Regular use of Zafnol helps reduce the risk of heart attack, stroke, and other cardiovascular complications.
