Isoptin Rr (Verapamil Hydrochloride)

Verapamil blocks L‑type calcium channels in cardiac muscle and vascular smooth muscle. By reducing calcium influx, it decreases myocardial contractility, slows conduction through the atrioventricular node, and relaxes arterial smooth muscle, leading to lower heart rate, reduced oxygen demand, and decreased peripheral vascular resistance.

The specific dose of Isoptin Rr is determined by the prescribing healthcare professional based on the individual’s clinical condition, response, and tolerability. Dosage may be adjusted for hypertension, angina, or arrhythmia, and should follow the physician’s written instructions.

Safety of verapamil during pregnancy or lactation has not been definitively established. Healthcare providers weigh potential benefits against possible risks, and the drug is generally used only if clearly needed. Women who are pregnant, planning pregnancy, or breastfeeding should discuss alternatives with their physician.

To request Isoptin Rr, submit an enquiry on the product page at gnhindia.com, specifying the required quantity. GNH India works with hospitals, pharmacies and procurement teams worldwide, verifies trade or institutional credentials, and then provides pricing, availability, shipping details and any necessary import documentation.

Compared with beta‑blockers or ACE inhibitors, verapamil primarily lowers blood pressure by vasodilation and decreasing cardiac contractility, and it also possesses anti‑arrhythmic properties. It may be chosen when rate control of supraventricular tachyarrhythmias is required, but it can interact with other cardiac drugs and may cause constipation more frequently.

Isoptin Rr should be stored at ambient temperature, preferably below 25 °C, in its original packaging to protect from moisture and light. Keep the product out of reach of children and do not use if the packaging is damaged.

The medication is taken orally, usually with a glass of water. It can be taken with or without food, but patients should follow the prescribing clinician’s instructions regarding timing and whether to split or swallow whole tablets.

Serious adverse events include marked bradycardia, severe hypotension, heart block, and rare cases of hepatic dysfunction or life‑threatening allergic reactions. Patients should seek immediate medical attention if they experience fainting, a very slow heart rate, chest pain, or signs of an allergic reaction such as rash, swelling or difficulty breathing.

Verapamil is contraindicated in patients with known hypersensitivity to the drug, severe left ventricular dysfunction, advanced atrioventricular block without a pacemaker, or uncontrolled heart failure. Caution is also advised in individuals with significant hepatic impairment or those taking interacting medications listed under major interactions.
