Calan 80 mg (Verapamil Hydrochloride): Educational Guide

Introduction

Calan 80 mg contains verapamil hydrochloride, a prescription medication that belongs to the class of drugs known as calcium channel blockers (CCBs). It is commonly prescribed to help manage high blood pressure, chronic stable angina, vasospastic angina, and certain supraventricular arrhythmias.

By relaxing blood vessels and slowing electrical conduction through the heart, Calan helps improve blood flow while reducing the heart’s workload. This makes it an important treatment option for a variety of cardiovascular conditions.

This guide is intended for educational and informational purposes only.

What Is Calan?

Calan is the brand name for verapamil hydrochloride, a medication that affects the movement of calcium into the muscle cells of the heart and blood vessels. Calcium plays a key role in muscle contraction, including the contraction of the heart and blood vessel walls.

The 80 mg tablet is an immediate-release formulation commonly prescribed for adults. Healthcare providers determine the most appropriate dosage based on the patient’s medical condition and treatment response.

How Calan Works

Verapamil works by blocking calcium channels within the heart and blood vessels.

Its effects include:

• Relaxing blood vessels
• Lowering blood pressure
• Improving blood flow
• Reducing the heart’s oxygen demand
• Slowing conduction through the atrioventricular (AV) node
• Helping regulate certain abnormal heart rhythms

These actions help support cardiovascular health in appropriately selected patients.

Approved Medical Uses

Healthcare providers may prescribe Calan for:

• High blood pressure (hypertension)
• Chronic stable angina
• Vasospastic (Prinzmetal) angina
• Certain supraventricular tachycardias (SVTs)
• Heart rate control in selected patients with atrial fibrillation or atrial flutter

Treatment decisions are individualized according to each patient’s health status.

Potential Benefits

When taken as prescribed, Calan may help:

• Lower elevated blood pressure
• Improve circulation
• Reduce chest pain episodes
• Improve exercise tolerance in patients with angina
• Help regulate certain heart rhythm disorders
• Reduce strain on the heart
• Lower the risk of complications related to uncontrolled hypertension

Dosage Information

Healthcare providers determine the appropriate dosage based on factors such as:

• Medical condition being treated
• Blood pressure readings
• Heart rate
• Liver function

• Grapefruit or grapefruit juice, which may affect verapamil levels

Healthcare professionals review medication lists carefully to reduce the risk of interactions.

Monitoring During Treatment

Routine monitoring may include:

• Blood pressure
• Heart rate
• Electrocardiograms (ECGs) when appropriate
• Liver function
• Assessment of symptom improvement
• Evaluation for medication side effects

Regular follow-up appointments help support safe and effective treatment.
