Which medication regimen requires an empty stomach for optimal effectiveness?

Entecavir
Ribavirin
Viekira Pak
Epclusa

The correct answer is: Entecavir

Entecavir requires an empty stomach for optimal effectiveness because it is best absorbed when taken on an empty stomach. Ribavirin and Viekira Pak do not need to be taken on an empty stomach, and in fact, Ribavirin should be taken with food to reduce stomach upset. Epclusa can be taken with or without food but it may be better absorbed when taken with food. Therefore, none of the other medication regimens have the same requirement as Entecavir.
