Buy Nicardia Retard 20 mg (Nifedipine SR) – Sustained‑Release Therapy for Hypertension & Angina

Nicardia Retard 20 mg contains nifedipine in an extended‑release formulation, designed for once‑daily dosing. Manufactured by J.B. Chemicals, it effectively controls high blood pressure and prevents stable and variant angina. 

How It Works

Nifedipine relaxes and dilates blood vessels by inhibiting calcium influx into vascular smooth muscle. This reduces cardiac workload, lowers blood pressure, and improves coronary circulation. 

Uses & Benefits

• Treatment of essential hypertension in adults to reduce stroke, heart attack, and renal risk. 
• Prophylaxis of chronic stable and vasospastic angina by improving oxygen delivery to heart muscle. 

Dosage & Administration

• Initial dose: 20 mg once daily, with or without food. Swallow tablet whole—do not crush or chew. 
• Time is flexible, but best taken at the same time each day for consistent levels. 
• Maximum usual dosage: up to 40 mg twice daily or 90 mg once daily in resistant cases.

Precautions & Interactions

• Contraindicated in acute myocardial infarction, unstable angina, severe aortic stenosis, hypersensitivity to nifedipine. 
• Avoid grapefruit juice—it raises nifedipine levels, increasing side effect risk. 
• Watch for drug interactions with CYP3A4 inhibitors (e.g., macrolides, antifungals) and inducers (e.g., rifampin, phenytoin). ([turn0search0], [turn0search5])
