Amitivir  (Synonyms: LY 217896)

Amitivir (LY 217896), a thiadiazole derivative, possesses broad antiviral activity against orthomyxo- and paramyxoviruses. Amitivir is effective against influenza A and B viruses^[1][2].

The mean 50% inhibitory concentration of Amitivir inhibits six strains of type A influenza (A/Russia, A/Brazil/11/78, A/Ann Arbor/1/57, A/Port Chalmers/1/73, A/Hong Kong/8/68 and A/X-15) ranged from 0.37 to 1.19 μg/ml. The mean 50% inhibitory concentration of Amitivir inhibits four strains of influenza B virus (B/Maryland/11/59, B/GreatLakes/1739/54, B/Singapore/3/64, B/Lee/40) ranged from 0.75 to 1.54 μg/ml^[2].

Amitivir (LY 217896) (9 mg/m² of body surface area per day) administered in the diet, in the drinking water, by oral gavage, by intraperitoneal injection, or by aerosolization was well tolerated and protected CD-1 mice infected with a lethal dose of influenza A or B virus^[2].
