Description

Zanamivir is a potent and selective neuraminidase inhibitor, a critical class of antiviral agents. Its primary value lies in its ability to effectively treat and prevent infections caused by influenza A and B viruses by blocking the release of viral particles from infected cells. This makes it an essential active pharmaceutical ingredient (API) for manufacturers of antiviral medications, particularly in the production of inhalation powders and other dosage forms. Global pharmaceutical companies and research institutions rely on high-purity Zanamivir CAS NO 551942-41-7 to develop reliable therapeutic solutions for seasonal and pandemic influenza.

Application

• Pharmaceutical API: Primary use as the active ingredient in antiviral drugs for the treatment of influenza.
• Inhalation Powder Formulations: Key component in dry powder inhalers (DPIs) such as Relenza® for direct delivery to the respiratory tract.
• Prophylactic Use: Manufacture of medications for the prevention of influenza in high-risk populations.
• Antiviral Research: Reference standard and building block in virology research and development of new neuraminidase inhibitors.
• Combination Therapies: Potential use in combination with other antiviral agents to enhance efficacy or combat resistance.
• Veterinary Pharmaceuticals: Investigation and potential application in treating influenza in animals.

Quality Control

Our Zanamivir is manufactured under strict quality management systems to ensure it meets the stringent requirements for pharmaceutical active ingredients. Quality is assured through comprehensive analytical testing, including identification, purity assay, and control of specified impurities. We can supply material compliant with various pharmacopeial standards, and a detailed Certificate of Analysis (COA) is provided with each batch to guarantee traceability and compliance.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed in a dry environment to prevent degradation.
