Participant Flow

This was an open-label, randomized, 4-way crossover trial. 36 patients were randomised to one of 4 treatment sequences and treated. Each treatment period consisted of a single dose of medication followed by 72 hours of pharmacokinetic sampling, with a washout of at least 7 days between treatment periods.

Population: Pharmacokinetic (PK) set: All subjects who took at least 1 dose of investigational treatment, provided at least 1 observation for at least 1 primary PK endpoint, did not have important protocol violations relevant to the evaluation of relative bioavailability, did not vomit at or before 2 times median tmax and did not use restricted medications

Area under the concentration-time curve of the analyte in plasma over the time interval from 0 extrapolated to infinity. In this endpoint, the "Measured values" shows inter-individual variabilities, whereas the statistical analyses show intra-individual variabilities.
