Cas no 204255-11-8 (Oseltamivir phosphate)
Oseltamivir phosphate is an antiviral prodrug specifically designed to inhibit the neuraminidase enzyme of influenza viruses, including types A and B. Its active metabolite, oseltamivir carboxylate, effectively blocks viral replication by preventing the release of progeny virions from infected host cells. This compound is clinically validated for the treatment and prophylaxis of influenza infections, demonstrating efficacy in reducing symptom duration and complication risks when administered early. Its oral bioavailability and well-characterized pharmacokinetic profile make it a practical option for outpatient and inpatient settings. Oseltamivir phosphate is synthesized under stringent quality controls to ensure purity and consistency, meeting pharmacopeial standards for therapeutic use.
