Definition

1. Noun:
   • A vasodilator drug used to treat severe hypertension: Diazoxide is a medication that works by relaxing and widening blood vessels, thereby lowering blood pressure. It is specifically indicated for hypertensive emergencies.
   • An antihyperglycemic agent: In a different medical context, diazoxide can also be used to treat hypoglycemia (low blood sugar) by inhibiting insulin release from the pancreas.

Examples of Usage

• Noun:
  • The doctor administered diazoxide to quickly lower the patient's critically high blood pressure.
  • Diazoxide is effective in managing hypertensive crises when rapid vasodilation is required.
  • For patients with certain insulin-secreting tumors, diazoxide can help control hypoglycemic episodes.

Advanced Usage

• "diazoxide therapy": Refers to the treatment regimen using this drug.
  • Initiating diazoxide therapy requires careful monitoring of blood pressure and blood glucose levels.

Variants and Related Words

Notes on Different Meanings

• Primary Meaning: The most common use of "diazoxide" is as a potent intravenous vasodilator for hypertensive emergencies.
• Secondary Meaning: It also has an oral formulation used to treat chronic hypoglycemia due to hyperinsulinism. This dual use stems from its mechanism of action on potassium channels.
