product characteristics
flibenserin is available as a 100 mg tablet intended to be taken orally once daily at bedtime (qhs). After oral administration, flibenserin absorption from the intentine is rapid and nearly complete. Maximum plasma concentration (C-max) occur 45 to 60 minutes after oral dosing with a half-life (t1/2) of approximately 10 hours. Steady state is achieved within three days. Food moderately affects the rate and extent of flibanserin absorption. Peak plasma concentrations of flibanserin occur at 1.75 to 4 hours post-dosing with food, and the extent of exposure is increased up to 56% after a high-fat, high-caloric meal. Grapefruit juice increases flibanserin exposure approximately 38% and Cmax by 10%. Cytochrome P450 (CYP)3A4-mediated biotransformation is responsible for most of flibanserin elimination, with negligible or minimal (
