Mean plasma ALA concentration–time profile for both formulations with and without inclusion of the
basic AUC are shown in Figs. 1 and 2, respectively. The AUC0–24 h, Cmax and Tmax with and without inclusion of
the basic AUC (for ALA only) are presented in Table 2. The parameters characterizing bioavailability of both ALA preparations were not statistically different between the treatments.
