Kel is the apparent first-order terminal elimination rate constant calculated from a semi-log plot of the plasma concentration versus time curve. The parameter was calculated by linear least-squares (LS) regression analysis using the maximum number of points (e.g., 3 or more non-zero plasma concentrations) in the terminal log-linear phase.

Timeframe: Up to day 2 (Period 3)

Population: PK analyses

Intensity was determined by the Investigator. For symptomatic Adverse Events (AEs) the following definitions were applied. Mild = AE did not limit usual activities; subject may have experienced slight discomfort. Moderate = AE resulted in some limitation of usual activities; subject may have experienced significant discomfort. Severe = AE resulted in an inability to carry out usual activities; subject may have experienced intolerable discomfort/pain. Relationship to Investigational Medicinal Products (IMP) Unlikely = Slight, but remote, chance that AE was caused by IMP. Possible = Reasonable suspicion that the AE was caused by IMP. Probable = Most likely that AE was caused by IMP.
