Pharmacokinetics of dihydroartemisinin in Artekin tablets for single and repeated dosing in Chinese healthy volunteers.

abstract：:Twenty-six healthy male volunteers received a single 10 mg dose of diazepam on two occasions in a crossover bioequivalence study comparing the reference product (Valium) and a generic formulation (NeoCalme). Concentrations of diazepam and its metabolite, desmethyldiazepam, were determined during 264h after each dose. ...
