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.

Controlled Product

CAS: 204255-11-8

Inhibitor of viral neuraminidase enzyme, effective against influenza A and B viruses. This antiviral compound inhibits neuraminidase-mediated cleavage of host cell sialic acids, which interact with newly synthesised virions from the host cell. This prevents virion budding from the host, resulting in inhibition of virion release and viral infection overall.
