<prompt> Which of the following statement about diazoxide is falseIt acts by causing prolonged opening of ATP dependent potassium channels in beta cellsIt can cause severe hypoglycemiaIt can be used to treat patients with insulinaemiaIt is used as an antihypeensive agent  <response>: Diazoxide cause hyperglycemia and not hypoglycemia Diazoxide is a potassium channel activator, which causes local relaxation in smooth muscle by increasing membrane permeability to potassium ions. This switches off voltage-gated calcium ion channels, preventing calcium flux across the sarcolemma and activation of the contractile apparatus Refer katzung 11e p180
