Diazoxide is a potassium channel activator. Its mechanism of action revolves around enhancing cell membrane permeability to potassium ions. This action consequently elicits the relaxation of local smooth muscles. This switches off voltage-gated calcium ion channels which inhibits the generation of an action potential.
- Mechanism of action
Diazoxide inhibits insulin release from the pancreas, by opening potassium channels in the beta cell membrane.2 Diazoxide is chemically related to thiazide diuretics but does not inhibit carbonic anhydrase and does not have chloriuretic or natriuretic activity.1 It also exhibits hypotensive activity by reducing arteriolar smooth muscle and vascular resistance.1
