4.2 Drug Indication

Used parentally to treat hypertensive emergencies. Also used to treat hypoglycemia secondary to insulinoma.


5 Pharmacology and Biochemistry
5.1 Pharmacology

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.


5.2 MeSH Pharmacological Classification

Antihypertensive Agents

Drugs used in the treatment of acute or chronic vascular HYPERTENSION regardless of pharmacological mechanism. Among the antihypertensive agents are DIURETICS; (especially DIURETICS, THIAZIDE); ADRENERGIC BETA-ANTAGONISTS; ADRENERGIC ALPHA-ANTAGONISTS; ANGIOTENSIN-CONVERTING ENZYME INHIBITORS; CALCIUM CHANNEL BLOCKERS; GANGLIONIC BLOCKERS; and VASODILATOR AGENTS. (See all compounds classified as Antihypertensive Agents.)


Vasodilator Agents

Drugs used to cause dilation of the blood vessels. (See all compounds classified as Vasodilator Agents.)


5.3 ATC Code

C - Cardiovascular system

C02 - Antihypertensives

C02D - Arteriolar smooth muscle, agents acting on

C02DA - Thiazide derivatives

C02DA01 - Diazoxide


V - Various

V03 - All other therapeutic products

V03A - All other therapeutic products

V03AH - Drugs for treatment of hypoglycemia

V03AH01 - Diazoxide


5.4 Absorption, Distribution and Excretion

Absorption

Readily absorbed following oral administration.


Route of Elimination

Proglycem is extensively bound (more than 90%) to serum proteins, and is excreted in the kidneys.


5.5 Metabolism/Metabolites

Hepatic.


5.6 Biological Half-Life

28 ±8.3 hours in normal adults.


5.7 Mechanism of Action

Diazoxide inhibits insulin release from the pancreas, by opening potassium channels in the beta cell membrane. Diazoxide is chemically related to thiazide diuretics but does not inhibit carbonic anhydrase and does not have chloriuretic or natriuretic activity. It also exhibits hypotensive activity by reducing arteriolar smooth muscle and vascular resistance.
