Calan 40mg Tablets (50’s) – Verapamil for High Blood Pressure, Angina & Heart Rhythm Control

Description

Calan 40mg Tablets contain Verapamil Hydrochloride, a calcium channel blocker used to treat high blood pressure (hypertension), angina (chest pain), and certain heart rhythm disorders such as supraventricular tachycardia (SVT) and atrial fibrillation.
It works by relaxing blood vessels and slowing the heart rate, helping the heart pump more efficiently and reducing its workload. Calan is often prescribed to lower the risk of heart attack, stroke, and other cardiovascular complications.
