Buy Calaptin 40 mg (Verapamil) – Calcium‑Channel Blocker for Hypertension, Angina & Arrhythmia

Calaptin 40 mg contains verapamil, a non-dihydropyridine calcium-channel blocker. Manufactured by USV, it’s used to treat high blood pressure, prevent angina attacks, and manage certain arrhythmias.

How It Works

Verapamil reduces calcium influx into cardiac and vascular smooth muscle, causing vasodilation, decreased peripheral resistance, slower AV conduction, and reduced heart rate — lowering blood pressure and improving coronary blood flow. 

Indications & Benefits

• Treatment of essential hypertension and various forms of angina (stable or vasospastic).
• Management of supraventricular tachyarrhythmias like atrial fibrillation/flutter and PSVT. 
• Non-dihydropyridine class provides heart rate control and antiarrhythmic effects. 

Dosage & Administration

• Immediate‑release: 40 mg TID (three times daily); up to 480 mg/day based on response. 
• Extended‑release formulations available for once-daily dosing; typical starting dose ~120–180 mg daily. 
• Swallow capsules whole. Routine ECG and blood pressure monitoring advised during titration. 

Side Effects & Safety

• Common: constipation (~7%), headache, dizziness, nausea, flushing, fatigue, peripheral edema.
• Cardiac: bradycardia, AV block, hypotension, heart failure exacerbation in ~2% of users.
• Other: gingival enlargement, elevated liver enzymes, rash, flushing.  

Precautions & Interactions

• Contraindicated in severe left ventricular dysfunction, cardiogenic shock, sick sinus syndrome or AV block without pacemaker, WPW syndrome, severe hypotension. 
• Avoid grapefruit juice—it increases blood levels significantly. 
• Drug interactions: caution with beta-blockers (risk of heart block), CYP3A4 inhibitors/inducers, digoxin, statins, lithium, theophylline.  
• Elderly and patients with liver or kidney impairment may require dose adjustment and monitoring.
