PRIMARY outcome

Timeframe: Blood samples collected over 120 hour period

Population: Two subjects did not complete the study, and there was an issue with dosing of one subject (the whole tablet was not consumed for one of the periods) therefore there are 29 data sets that were included in the statistical analysis.
