Primary Outcome Measures :
  1. Cmax (Maximum Observed Concentration) [ Time Frame: Blood samples collected over a 12 hour period ]
    Bioequivalence based on Cmax.

  2. AUC0-t (Area Under the Concentration-time Curve From Time Zero to Time of Last Measurable Concentration) [ Time Frame: Blood samples collected over a 12 hour period. ]
    Bioequivalence based on AUC0-t.

  3. AUC0-inf (Area Under the Concentration-time Curve From Time Zero to Infinity) [ Time Frame: Blood samples collected over a 12 hour period. ]
    Bioequivalence based on AUC0-inf.
