1-Factor ANOVA of Log-Transformed Data (Desvenlafaxine Postprandial Data Only)d
Treatment   0.015 0.667 0.408 0.063 0.144
ANOVA, analysis of variance; AUC, area under the plasma concentration-time curve; Cl/F, apparent oral-dose clearance; Cmax, peak drug concentration; ER, extended release; t1/2, terminal-phase elimination half-life; Tmax, time of peak concentration.
aData shown are geometric mean, minimum-maximum.
bExcluding 1 subject who vomited and exhibited very low plasma concentrations.
cExcluding 2 subjects who vomited and exhibited very low plasma concentrations.
dBefore statistical comparisons, Cmax and AUC were normalized to the lowest dose.
