Product Description:

Zanamivir is a neuraminidase inhibitor active against influenza A and B. Neuraminidase lets new virus particles leave an infected cell; blocking it traps them and slows spread in the airway. Zanamivir is poorly absorbed by mouth, so it is inhaled straight into the respiratory tract. This product is a dry powder: each blister holds 5 mg zanamivir with lactose, on a disk of four blisters used in a dedicated inhaler. A separate intravenous form exists in some markets.

It is used for treatment and prevention of influenza. Treatment is two inhalations, 10 mg, twice daily for five days, started within 48 hours of symptoms; the label sets age limits. Prevention after household contact or in outbreaks uses two inhalations once daily. Bronchospasm can occur, so it is generally not recommended in asthma or chronic lung disease. The powder must never be dissolved for nebulisation or used in a ventilator, as lactose can block equipment. It does not replace vaccination.

Sourcing notes. Each pack should contain the inhaler and the disks, with illustrated patient instructions; check that both come together and ask about device spares. Registration needs a CTD dossier covering the powder, the device and delivered-dose uniformity. Storage is at room temperature in a dry place. Lactose is milk-derived, so labels must declare it. Pandemic stockpiles buy in volume, so ask about shelf life and any approved extension. Ask for a CoA with each batch, plus the GMP certificate and a CoPP. It is prescription-only in most markets. Specify packs, quantity and market.
