Calaptin SR

Product Overview

Calaptin SR is a prolonged-release medication containing Verapamil as its active ingredient. This formulation is designed to provide gradual and sustained drug delivery over time. As a calcium channel blocker, Verapamil is widely prescribed for managing cardiovascular conditions. Calaptin SR effectively controls blood pressure, alleviates angina (chest pain), and manages specific cardiac rhythm disorders by relaxing blood vessels and decreasing cardiac workload.

Uses

This medication is primarily indicated for treating hypertension (high blood pressure) through blood pressure reduction and improved circulation. It’s also effective for chronic stable angina management, decreasing both the frequency and intensity of angina attacks. Furthermore, Calaptin SR may be prescribed to regulate certain cardiac arrhythmias like atrial fibrillation or atrial flutter by normalizing heart rate and rhythm.

How to Use

Take Calaptin SR tablets orally exactly as prescribed, typically once daily with water. Swallow tablets whole without crushing, chewing, or breaking to maintain the prolonged-release properties. While food doesn’t significantly affect absorption, maintain consistent timing relative to meals. Strictly adhere to your physician’s dosage and administration instructions.

How it Works

Verapamil in Calaptin SR inhibits calcium channels in vascular smooth muscle and cardiac cells. This mechanism causes vasodilation through vascular relaxation, reducing peripheral resistance and consequently lowering blood pressure. The medication also decreases cardiac workload while enhancing myocardial blood flow, thereby relieving angina. Additionally, it modulates cardiac electrical impulse conduction, helping stabilize heart rhythm.

Dosage and Administration

Calaptin SR dosing is personalized based on individual patient needs and therapeutic response. Treatment typically begins with lower doses, gradually adjusted under medical supervision. The standard adult starting dose is 180 mg once daily, preferably in the morning. Never exceed prescribed dosages without medical consultation.

Benefits

• Effective blood pressure control with reduced cardiovascular risk
• Symptomatic relief from angina and enhanced physical endurance
• Cardiac rhythm stabilization for specific arrhythmias
• Convenient once-daily dosing with sustained-release technology
• Generally well-tolerated with minimal adverse effects

Common Side Effects

Typical side effects may include constipation, dizziness, headaches, fatigue, and nausea. These are usually mild and temporary, often resolving with continued therapy or dosage modification. Consult your healthcare provider if symptoms persist or worsen.

Warnings

Exercise caution when using Calaptin SR if you have heart failure, hepatic/renal impairment, or hypotension. Potential drug interactions exist with beta-blockers, digoxin, and statins—disclose all medications to your doctor. Avoid grapefruit products as they may enhance adverse effects. Never discontinue abruptly without medical advice to prevent rebound hypertension or angina exacerbation.

Storage Information

Store at room temperature in a dry place, protected from heat and moisture. Keep out of children’s and pets’ reach. Do not use if packaging appears compromised. Proper storage maintains medication stability and efficacy.
