Buy Calaptin SR 240 mg (Verapamil SR) – Extended‑Release for BP, Angina & Arrhythmia

Calaptin SR 240 mg is a sustained‑release formulation of verapamil hydrochloride, equivalent to Calan SR 240 mg. Manufactured by Abbott (India), it’s used to treat hypertension, angina pectoris, and certain supraventricular arrhythmias. 

How It Works

Verapamil is a non‑dihydropyridine calcium channel blocker. It relaxes arterial and coronary blood vessels and slows atrioventricular conduction, lowering heart rate and workload. This improves circulation and relieves angina, while controlling blood pressure and abnormal heart rhythms.

Indications & Benefits

• Treats essential hypertension, reducing the risk of stroke and heart attack. 
• Manages chronic stable angina—including vasospastic and exercise-induced types. 
• Controls supraventricular tachycardia and atrial fibrillation/flutter rate when appropriate. 

Dosage & Administration

• Initial dosing often starts at 180 mg once daily in the morning. If needed, increase to 240 mg once daily. Further titration may include 240 mg BID.
• Take with food, at the same time daily. Do not crush or chew.

Common Side Effects

• Constipation (most frequent), dizziness, headache, nausea, swelling in legs, fatigue, hypotension. Usually mild and transient.

Serious Side Effects & Safety Alerts

• Potential for bradycardia, heart block, heart failure or pulmonary edema—especially at higher doses or in susceptible patients. 
• Liver dysfunction: look out for dark urine, yellowing skin or upper abdominal pain. 
• Angioedema or serious allergic reactions—seek immediate medical attention. 

Precautions & Drug Interactions

• Avoid grapefruit and grapefruit juice—they increase verapamil levels and side effects. 
• Avoid alcohol—can worsen dizziness or low blood pressure. 
• Caution when taking beta‑blockers, digoxin, statins, or other blood-pressure medications; these may interact or raise risk of conduction slowing. 
• Use cautiously in severe liver or kidney disease, heart failure, AV block, hypotension, or WPW syndrome.
• Do not discontinue suddenly—gradual taper is needed to avoid rebound hypertension or arrhythmia.
