For Pharmacists:

Medicine Name: Advant
Brand: Advant
Active Ingredient(s): Candesartan Cilexetil 8 mg

Indications:

• Hypertension.
• Heart failure with reduced ejection fraction (HFrEF).

Pharmacodynamics:

• Mechanism of Action:
  Candesartan is an angiotensin II receptor blocker (ARB) that selectively blocks the binding of angiotensin II to the AT1 receptor, preventing vasoconstriction and aldosterone secretion.
• Pharmacological Effects:
  • Reduces blood pressure.
  • Improves cardiac output in heart failure patients.
• Receptor Binding:
  High affinity for AT1 receptors, leading to effective and prolonged blockade of angiotensin II-mediated effects.

Pharmacokinetics:

• Absorption: Well absorbed; bioavailability ~15% after oral administration.
• Distribution: Highly protein-bound (~99%).
• Metabolism: Prodrug converted to active candesartan by ester hydrolysis in the gastrointestinal tract.
• Elimination: Primarily excreted in urine and bile.
• Half-Life: Approximately 9 hours.
• Effect of Food: Food does not significantly affect absorption.

Dosage and Administration:

• Adults:
  • Hypertension: 8 mg once daily.
  • Heart Failure: Start with 4 mg daily, titrate up to 32 mg as tolerated.
• Special Populations:
  • Lower doses may be required for patients with renal or hepatic impairment.
