Population: According to the protocol, the "pharmacokinetic population" should include all subjects who had valid data for all treatment periods. In this study, 18 subjects completed 2 treatment periods, 17 subjects completed 3 treatment periods and 16 subjects completed all 4 treatment periods.

Pharmacokinetic parameters of BIA 9-1067. For tmax = time to Cmax values are presented as median with range values.
