↵*Summary statistics of pharmacokinetic and pharmacodynamic parameters; does not reflect results of the statistical analysis.
↵†The test treatment in each comparison.
↵‡Statistical model: log(parameter) = period + sequence + treatment + error, subject (random), period sequence treatment (categorical).
↵§Median or median difference (95% CI) are presented for tmax. tmax was analyzed using a nonparametric approach based on the Hodges-Lehmann method. Analysis was based on subject's tmax values averaged across the 2 occasions where the same treatment was administered, if applicable.
