Description

Laninamivir (R-125489), a new neuraminidase (NA) inhibitor, was discovered, and in this study, its NA inhibitory activities against various influenza viruses including oseltamivir-resistant viruses are reported. Laninamivir octanoate, has been approved for use in Japanese clinics for the treatment and prevention of influenza in both adults and children. The inhaled laninamivir octanoate is converted into its active form, laninamivir, in the lungs where a high concentration persists for a long period of time.

Sample Use Guides

In Vivo Use Guide
1. For treatment of the influenza virus Adults: A single inhaled dose of 40 mg of laninamivir octanoate Children: If less than 10 years old, a single inhaled dose of 20 mg of laninamivir octanoate If 10 years old or older, a single inhaled dose of 40 mg. 2. For prevention of the influenza virus Adults and children over 10 years of age: Daily single inhaled dosage of 20 mg of laninamivir octanoate for two days
Route of Administration: Respiratory
In Vitro Use Guide
Laninamivir (R-125489) neuraminidase inhibitory activity depends on virus strain. IC50 values lie in low nanomolar range.
