Zanamivir (hydrate)(5:1) 

Zanamivir hydrate (5:1) is the hydrate of Zanamivir. Zanamivir is an influenza viral neuraminidase inhibitor with IC₅₀ values of 0.95 nM and 2.7 nM for influenza A and B, respectively^[1].

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

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].

MCE has not independently confirmed the accuracy of these methods. They are for reference only.
