Calan 80mg Tablets (50’s) – Verapamil for High Blood Pressure, Angina & Heart Rhythm Control

Description

Calan 80mg Tablets contain Verapamil Hydrochloride, a calcium channel blocker used to effectively manage high blood pressure (hypertension), angina (chest pain), and certain heart rhythm disturbances such as supraventricular tachycardia (SVT) and atrial fibrillation.
By relaxing the blood vessels and slowing the heart rate, Calan helps the heart work more efficiently, reduces chest pain, and lowers the risk of heart attacks, stroke, and other cardiovascular complications.
