Isoptin Rr Retard (Verapamil Hydrochloride)

Verapamil blocks L‑type calcium channels in cardiac and vascular smooth‑muscle cells, reducing calcium entry. This leads to decreased myocardial contractility, slowed atrioventricular nodal conduction, and arterial vasodilation, which together lower blood pressure and stabilize heart rhythm.

The exact dosage of Isoptin Rr Retard is determined by the prescribing healthcare professional based on the patient’s condition, response to therapy, and other clinical factors. Patients should follow the prescriber’s instructions and not adjust the dose on their own.

Safety of verapamil during pregnancy or lactation has not been definitively established. Healthcare providers should weigh potential benefits against possible risks and consider alternative therapies when appropriate. Women who are pregnant, planning pregnancy, or breastfeeding should discuss options with their physician.

Isoptin Rr Retard (verapamil) is a non‑dihydropyridine calcium channel blocker, distinguished by its pronounced effects on cardiac conduction and contractility. Compared with dihydropyridine agents such as amlodipine, verapamil provides stronger rate‑control for arrhythmias but may cause more bradycardia and AV‑node slowing.

Store Isoptin Rr Retard at room temperature, preferably below 25 °C. Keep the tablets in the original packaging, protect them from moisture and direct sunlight, and ensure they are out of reach of children.

Isoptin Rr Retard is taken orally, usually as a prolonged‑release tablet. It should be swallowed whole with a glass of water and taken at the same time each day, unless the prescriber advises otherwise.

Serious risks include severe bradycardia, heart block, and marked hypotension, which can be life‑threatening. Patients should be monitored for signs of these events, especially when initiating therapy or when combined with other agents that affect cardiac conduction.

Isoptin Rr Retard is contraindicated in patients with known hypersensitivity to verapamil, severe left ventricular dysfunction, advanced heart block without a pacemaker, and in those with uncontrolled heart failure. Clinicians should evaluate each patient’s medical history before prescribing.
