About Inavir®

Inavir® is the first drug of a new class of long acting neuraminidase inhibitors (LANIs) to address the limitation of the current products, which require daily or more frequent dosing. The new class provides the opportunity to medicate patients on a "one and done" basis and offers a number of potential benefits. These include that the patient is more likely to use the product properly and as intended and also offers a reduced cost of storage and transport per course, where the product is intended to be stockpiled. Inavir® is Daiichi Sankyo's registered brand for laninamivir octanoate, also previously known as CS-8958. Inavir® is delivered via a Dry Power Inhaler.
