Calcium Channel Blockers, intravenous

Intravenous calcium channel blockers are a parenteral drug class consisting of vascular- and cardiac-active agents formulated for rapid systemic administration This inhibition induces direct arterial vasodilation to reduce peripheral resistance, while non-dihydropyridine formulations additionally suppress sinoatrial and atrioventricular nodal conduction and myocardial contractility Clinically, these intravenous formulations are primarily indicated for the acute management of severe hypertension ...

Intravenous calcium channel blockers are a parenteral drug class consisting of vascular- and cardiac-active agents formulated for rapid systemic administration Clinically, these intravenous formulations are primarily indicated for the acute management of severe hypertension and hypertensive crises, perioperative blood pressure control, and rapid ventricular rate reduction in supraventricular tachyarrhythmias, such as atrial fibrillation and atrial flutter

They function by selectively inhibiting transmembrane calcium ion influx via voltage-gated L-type calcium channels in vascular smooth muscle and cardiac myocytes
