Pharmacokinetics and bioequivalence study of a generic desloratadine tablet formulation in healthy male volunteers.

The pharmacokinetic profiles and relative bioavailability of desloratadine (CAS 100643-71-8, Denosin as test and another commercially available preparation as reference) tablets from two different pharmaceutical manufacturers were carried out. A single oral dose (10 mg/2 tablets) of desloratadine was administered to 8 healthy young Chinese males in a completely double-blind cross-over design with a two-week washout period between each dose. Plasma samples were obtained before and at various appropriate intervals after dosing up to 120 h.
