Summary
In Vivo
The prodrug, LB80380, is rapidly absorbed after oral administration (30, 60, 120, 240 mg) and is converted to its parent drug, Besifovir (LB80331) (LB80380 was not detected in plasma). The median T max s of LB80331 ranged from 1.0 to 2.0 h postdosing. Thereafter, the plasma LB80331 concentration declined in a monoexponential manner, and the mean values of t 1/2 ranged from 2.5 to 3.3 h [2] .
MCE has not independently confirmed the accuracy of these methods. They are for reference only.
