Pharmacokinetics of fluvoxamine maleate after increasing single oral doses in healthy subjects.

The pharmacokinetics of fluvoxamine after single oral administration of 25, 50, and 100 mg fluvoxamine maleate was studied in a three-way cross-over study in 12 healthy male subjects. Fluvoxamine was administered orally in a solution. For dose-proportionality, AUC, and Cmax-dose relationships were evaluated by linear regression. Plasma concentrations increased in a linear dose-dependent manner in the dose range between 25 and 100 mg; t1/2 and Tmax showed no significant differences among treatments. Fluvoxamine was well tolerated.
