Design outcomes

Primary

MeasureTime frame
Comparison of AUC0-8h between the two formulations. The CBD content in the plasma samples is determined at 0 h, 0.5 h, 1 h, 2 h, 3 h, 4 h, 5 h, 6 h, 8 h and 24 h. The characteristics are determined from the concentration-time curves.

Secondary

MeasureTime frame
Comparison of the following pharmacokinetic endpoints between the two formulations: AUC0-24h, Cmax, Tmax. The characteristics are calculated from the plasma concentration-time curves, see above.
