CAS 204255-11-8: Oseltamivir phosphate
Description:Oseltamivir phosphate, with the CAS number 204255-11-8, is an antiviral medication primarily used to treat and prevent influenza A and B. It is a prodrug, meaning it is metabolized in the body to its active form, oseltamivir carboxylate, which inhibits the neuraminidase enzyme on the surface of the influenza virus, thereby preventing the virus from spreading within the respiratory tract. Oseltamivir phosphate is typically administered orally and is available in capsule and liquid formulations. The substance is characterized by its chemical formula, which includes elements such as carbon, hydrogen, nitrogen, oxygen, and phosphorus. It is soluble in water and exhibits a moderate molecular weight. The drug is generally well-tolerated, with common side effects including nausea and vomiting. Oseltamivir phosphate is most effective when taken within the first 48 hours of influenza symptom onset, making timely administration crucial for optimal therapeutic outcomes.
