Abstract
- Vortioxetine is an antidepressant with multimodal activity approved for the treatment of major depressive disorder. Two separate randomized, placebo-controlled trials evaluated the effects of multiple doses of vortioxetine (10 mg/day) on the pharmacokinetics and pharmacodynamics of aspirin and warfarin in healthy volunteers. In the aspirin study, subjects received vortioxetine 10 mg or placebo once daily for 14 days, followed by coadministration with aspirin 150 mg once daily for 6 days, in 2 periods with a crossover design. In the warfarin study, subjects were randomized after reaching target international normalized ratio (INR) values on warfarin to receive vortioxetine 10 mg or matching placebo once daily for 14 days, with all subjects receiving a maintenance dose of warfarin (1-10 mg). Vortioxetine had no effect on the steady-state pharmacokinetic parameters of aspirin or its metabolite salicylic acid, and no statistically significant effect on the inhibition of arachidonic acid-, adenosine-5′-diphosphate-, or collagen-induced platelet aggregation at any time points. Coadministration of vortioxetine did not alter the pharmacokinetics of ( R)- and ( S)-warfarin enantiomers, or the mean coagulation parameters of warfarin treatment alone. Coadministration of vortioxetine doses in healthy volunteers had no effect on aspirin or warfarin pharmacokinetics or pharmacodynamics. Vortioxetine was well tolerated when coadministered with aspirin or warfarin. [ABSTRACT FROM AUTHOR]
