Buy Calaptin SR 120 mg (Verapamil Sustained‑Release) – Once‑Daily Treatment for Hypertension, Angina & Arrhythmia

Calaptin SR 120 mg contains verapamil hydrochloride in a sustained‑release form, designed to release medication steadily over 24 hours. Manufactured by Abbott (India), it’s used in treating high blood pressure, angina pectoris, and certain heart rhythm disorders. 

How It Works

Verapamil is a non‑dihydropyridine calcium‑channel blocker. It relaxes blood vessels, reduces heart workload, slows heart rate, and improves coronary blood flow—all without dramatically lowering cardiac contractility. 

Uses & Benefits

• Treats hypertension by lowering vascular resistance. ([turn0search15], 
• Relieves chronic or variant angina by improving oxygen supply-demand ratio. 
• Controls supraventricular tachycardia and slows ventricular rate in atrial fibrillation/flutter. 
• Sometimes prescribed off-label for migraine prevention through vascular regulation. 

Dosage & Administration

• Typical dose: 120 mg once daily with food. Do not split, crush, or chew the tablet. 
• Maintenance dose may be adjusted up to 240–480 mg daily depending on clinical response and tolerance. Doses over 240 mg may require twice‑daily administration. 
• If a dose is missed, take it when remembered unless it’s near the next one; do not double dose. Resume regular dosing schedule. 

Side Effects & Safety

• Common: constipation, dizziness, nausea, headache, fatigue, peripheral edema, low blood pressure. 
• Other: flushing, indigestion, muscle/joint pain, cold sweats, shortness of breath. 
• Serious (rare): bradycardia, AV block, heart failure exacerbation—especially in patients with underlying cardiac conditions.

Precautions & Interactions

• Contraindicated in cardiogenic shock, severe left ventricular dysfunction, second/third‑degree AV block, sick sinus syndrome, hypotension, and pacemaker dependency unless used under supervision.
• Do not abruptly stop—may lead to rebound hypertension or arrhythmias. Taper only under physician guidance. 
• Avoid combining with beta‑blockers or other AV‑nodal blockers without close monitoring. 
• Avoid grapefruit products and limit alcohol—these may raise blood verapamil levels or worsen side effects. 
• Use with caution in liver or kidney disease and in the elderly—dose adjustments may be required.
