Isoptin (Verapamil Hydrochloride)

Verapamil blocks L-type calcium channels in cardiac and vascular smooth muscle, decreasing calcium entry. This reduces myocardial contractility, slows AV‑node conduction, and causes peripheral vasodilation, which together lower blood pressure and lessen cardiac workload.

The dose of Isoptin is determined by the prescribing healthcare professional based on the patient’s clinical condition, response to therapy, and any relevant laboratory parameters. No fixed regimen is provided here.

The pregnancy category for verapamil hydrochloride is not definitively established. Use during pregnancy or lactation should only occur when clearly needed and after consultation with a qualified healthcare provider.

To order Isoptin, submit an enquiry on the product page at gnhindia.com specifying the required quantity. GNH India supplies hospitals, pharmacies and procurement teams worldwide, verifies trade or institutional credentials, and then provides pricing, availability, shipping details (including any cold‑chain requirements) and necessary import documentation.

Isoptin (verapamil) is a non‑dihydropyridine calcium channel blocker, primarily affecting cardiac conduction and contractility, whereas dihydropyridine agents (e.g., amlodipine) mainly cause peripheral vasodilation. Verapamil is therefore preferred when rate control of arrhythmias is needed, while dihydropyridines are often chosen for isolated hypertension.

Isoptin should be stored at 2‑8 °C, kept refrigerated, protected from light, and should not be frozen or shaken. Use aseptic technique when preparing the intravenous solution and discard any unused portion after the recommended in‑use period.

Isoptin is administered by intravenous infusion under the supervision of a qualified healthcare professional. The infusion rate and duration are set by the prescriber, and patients are monitored for blood pressure, heart rate and any adverse reactions throughout the administration.

Serious risks include severe hypotension, marked bradycardia, and heart block, which can lead to syncope or cardiac arrest. Prompt recognition and management are essential, and patients should be monitored continuously during intravenous infusion.

Isoptin is contraindicated in patients with known hypersensitivity to verapamil or other calcium channel blockers, those with severe hypotension, advanced heart block without a pacemaker, and in patients with certain types of cardiogenic shock. Clinical judgment is required for other special populations.
