Cardiolite (50mg) 100 Tablets – Atenolol Beta-Blocker for Blood Pressure, Angina & Heart Rhythm Control

Description

Cardiolite 50mg Tablets contain Atenolol, a beta-blocker used to treat high blood pressure (hypertension), angina (chest pain), and irregular heart rhythms (arrhythmias).
Atenolol works by slowing down the heart rate and reducing the heart’s workload, helping the heart pump blood more efficiently and lowering the risk of heart attacks, strokes, and other cardiovascular complications.
