Research Excerpts

Overview

ExcerptReference
"Laninamivir octanoate is a recently developed inhaled neuraminidase inhibitor for treating influenza virus infection. "( Fujii, T; Higashiguchi, M; Matsumoto, T, 2018)
"Laninamivir is a novel long-lasting NAI that has demonstrated in vitro activity against influenza A and B viruses, and its prodrug (laninamivir octanoate) is in phase II clinical trials in the United States and other countries."( Abed, Y; Boivin, G; Desrochers, FM; Hamilton, S; Luttick, A; Pryor, MJ; Samson, M; Tucker, SP, 2014)
"Laninamivir is a 7-methoxy derivative of zanamivir, but a single dose is effective when taken as the laninamivir octanoate prodrug."( Barrett, S; McKimm-Breschkin, JL, 2015)
"Laninamivir is a long-acting antiviral requiring only a single dose for the treatment of influenza infection, making it an attractive alternative to existing neuraminidase inhibitors that require multiple doses over many days. "( Hurt, AC; Margo, K; Morton, DA; Mosse, J; Oh, DY; Panozzo, J; Piedrafita, D, 2015)
"Laninamivir octanoate is an inhaled drug with unique characteristics."( Ikematsu, H; Kawai, N, 2011)

Effects

ExcerptReference
"Laninamivir octanoate has displayed clinical efficacy comparable to that of oseltamivir and zanamivir against the H1N1 pandemic influenza strain from 2009, seasonal H3N2 influenza and influenza B viruses."( Ikematsu, H; Kawai, N, 2011)
