IC50: 0.95 nM (Influenza A); 2.7 nM (Influenza B)[1]

In Vitro Zanamivir interacts with a group of amino acids in the active site of neuraminidase, which are conserved in all influenza A and B strains. Zanamivir blocks the action of neuraminidase, which prevents the cleavage of sialic acid on the cell receptors, thus preventing release and spread of the newly formed virions[2].
In Vivo Zanamivir has a poor bioavailability in oral administration, with only 4–17% of the agent. Oral delivery of zanamivir has been a problem due to its strong hydrophilic nature that limits its transport across the intestinal epithelium. Permeation enhancers such as sodium cholate, hydroxypropyl β-cyclodextrin could be used with zanamivir to enhance the intestinal permeability[3].
Animal Admin Rats: Formulations PO-SC (Zanamivir with SC for p.o.) and PO-C (Zanamivir control solution for p.o.) are administered orally at a Zanamivir dose of 10 mg/kg, and IV-R (reference Zanamivir saline solution for i.v.) is administered i.v. at a dose of 1 mg/kg to rats under conscious condition. Blood samples are collected prior to and at 0.5, 1, 2, 3, 4, 6, 8, and 24 hr after administration. At each sampling point, three rats from each group are sacrificed after blood collection to extract the lungs. The lungs are cleansed with saline after extraction of lungs from the rats through a chest incision. The lungs are then transferred into E-tube and stored in the freezer (-80°C) until analysis. Plasma samples are harvested by centrifugation at 1,500 × g for 10 min and stored at -20°C until analysis. The analysis of Zanamivir in both plasma and lungs is performed using before-mentioned LC-MS/MS method[3].
