Pharmacological and pharmacokinetic properties

  • Mechanism of action : Iseltamivir is an antiviral drug. which is a strong and specific inhibitor of enzymes Neuraminidase of the influenza virus This enzyme is important in the division of the Koi virus. It acts to cut Sialic Acid from Glycoconjugate. Causes viruses to be released from infected cells. Prevents virus aggregation after being released from the host cell and may reduce the virus-attenuating properties of respiratory secretions. When tested in vitro, oseltamivir is effective against both types of influenza virus. A and B, and this medicine is effective against influenza A virus from certain breeds of poultry. Iseltamivir was also effective against influenza A virus from poultry (H5N1 strain), which has been isolated. Obtained from patients in Vietnam and Thailand during 2004.

  • Pharmacokinetics : Oseltamivir is rapidly absorbed from the gastrointestinal tract when administered orally as oseltamivir phosphate and is converted to active metabolites by hepatic esterases. At least 75% of the administered drug is absorbed into the bloodstream as active metabolites. The levels of active metabolites in the blood are highest within 2-3 hours after ingestion. They have an average distribution size of approximately 23 liters in humans. They bind to approximately 3% of plasma proteins. They have a half-life of 6-10 hours and More than 99% is excreted through the kidneys.

  • Oseltamivir is not recommended for use in children under 1 year of age because the exact rate of growth of the blood-brain barrier in humans is not known and the toxicological data reported in Will the animal be clinically relevant to the infant?

  • Safety and pharmacokinetics in patients with hepatic impairment haven't been evaluated.

  • Dosage adjustment is recommended in patients with a creatinine clearance of 10-30 mL/min. Dosage adjustments are not applicable in patients with end-stage renal failure (eg, creatinine clearance less than 10 mL/min) and patients receiving hemodialysis. (Hemodialysis) or dialysis by inserting fluid into the peritoneal cavity (Peritoneal dialysis)

  • Postmarketing, there have been reports of self-harm and delirium in influenza patients taking oseltamivir. (Mostly occurring in Japan) Often reported in pediatric patients.
