Calaptin SR 240 mg

Calaptin SR 240mg is a sustained-release formulation of Verapamil, a calcium channel blocker primarily used to manage hypertension, angina, and certain heart rhythm disorders. By inhibiting calcium influx into cardiac and vascular smooth muscle cells, it promotes vasodilation, reducing blood pressure and cardiac workload.

This slow-release formulation ensures steady therapeutic effects, minimizing fluctuations in drug levels. It may also be prescribed for migraine prevention and cluster headaches.

Common side effects include dizziness, fatigue, constipation, and low blood pressure. Patients with severe heart conditions or liver impairment should use it cautiously.

Uses

Calaptin SR 240mg (Verapamil Sustained Release) is used for:

• Hypertension (High Blood Pressure) – Helps lower blood pressure by relaxing blood vessels.
• Angina (Chest Pain) – Reduces heart workload and improves oxygen supply.
• Arrhythmias (Irregular Heartbeats) – Treats conditions like atrial fibrillation and supraventricular tachycardia.
• Migraine Prevention – Helps reduce the frequency and severity of migraines.
• Cluster Headaches – Sometimes used as a preventive treatment.
• Hypertrophic Cardiomyopathy – Manages symptoms by improving heart function

How to use it ?

Calaptin SR 240mg should be taken orally, usually once daily or as prescribed by a doctor. Swallow the tablet whole with water, without crushing or chewing, to maintain its sustained-release effect. It can be taken with or without food, but consistency is key.

Avoid grapefruit juice, as it may interfere with drug absorption. Do not skip doses; take it at the same time daily. If a dose is missed, take it as soon as possible, but never double the dose.

How dose it works ?

Calaptin SR 240mg (Verapamil) works by blocking calcium channels in the heart and blood vessels. It inhibits calcium influx into cardiac muscle and vascular smooth muscle cells, leading to relaxation of blood vessels and a reduction in heart workload.

This results in lower blood pressure, improved oxygen supply to the heart, and controlled heart rate in arrhythmias. Its sustained-release formulation ensures a gradual, long-lasting effect, preventing sudden fluctuations in drug levels.

This helps in managing hypertension, angina, and certain heart rhythm disorders effectively.

Dosage

• Hypertension & Angina: Typically 240 mg once daily; may be adjusted by a doctor based on response.
