Patient summary
Isoptin SR is verapamil 120mg and 240mg in a modified-release tablet for hypertension, angina and arrhythmia, blocking calcium influx across the day.
Mechanism of action
Isoptin SR works by blockading transmembrane calcium ion influx in cardiac and vascular smooth muscle membranes. This reduces peripheral resistance, lowers blood pressure, and slows conduction through the AV node, providing rhythm control and angina relief.
