Plasma pharmacokinetic parameters of MK-0524 and radioactivity following administration of a single p.o. dose of 40 mg of[14C]MK-0524 to healthy adult male subjects
Six healthy volunteers received 40 mg/202.4 μCi [14C]MK-0524 in two drug-filled capsules. Radioactivity in plasma was determined by liquid scintillation counting. Concentrations of MK-0524 were determined by an LC/MS/MS assay.
