Brand: Acylex
Active Ingredient(s): Acyclovir 200 mg

Indications:

• Treatment of HSV infections, including genital herpes and cold sores.
• Management of chickenpox in immunocompetent individuals.

Pharmacodynamics:

• Mechanism of Action:
  Acyclovir is a synthetic nucleoside analogue. It inhibits viral DNA replication by selectively targeting viral DNA polymerase, leading to chain termination.
• Pharmacological Effects:
  • Reduces viral replication and symptoms.
  • Prevents recurrence in suppressive therapy.
• Receptor Binding:
  Binds specifically to viral DNA polymerase, blocking the elongation of viral DNA strands.

Pharmacokinetics:

• Absorption: Oral bioavailability is approximately 10-20%.
• Distribution: Widely distributed in body fluids, including cerebrospinal fluid (CSF).
• Metabolism: Minimal; activated within infected cells.
• Elimination: Excreted unchanged in urine via glomerular filtration and tubular secretion.
• Half-Life: Approximately 2.5-3.3 hours in adults with normal renal function.
• Effect of Food: Food does not significantly affect the drug’s absorption.

Dosage and Administration:

• Adults:
  • HSV Treatment: 200 mg five times daily for 10 days.
  • Suppression: 200 mg four times daily or 400 mg twice daily.

Contraindications:

• Hypersensitivity to acyclovir or any component of the formulation.

Warnings and Precautions:

• Monitor renal function in elderly patients or those with renal impairment.
• Ensure adequate hydration to reduce the risk of renal toxicity.

Drug-Drug Interactions:

• Probenecid can increase acyclovir plasma levels.
• Concomitant use with nephrotoxic drugs can heighten the risk of kidney damage.

Drug-Food Interactions:

• Food does not significantly alter the drug’s absorption or efficacy.

Adverse Reactions:
