Primary Outcome Measures:
  • Area Under the Plasma Concentration Versus Time Curve Within a Dosing Interval at Steady-State (AUCss) for Sulfamethoxazole [ Time Frame: Assessed over a 24-hour period starting post-dose on day 4 ]
    AUC can be used as a measure of drug exposure. It is derived from drug concentration and time so it gives a measure of how much and how long a drug stays in a body.

  • Maximum Plasma Concentration at Steady-State (Cmaxss) for Sulfamethoxazole [ Time Frame: Assessed over a 24-hour period starting post-dose on day 4 ]
    Cmax is a term that refers to the maximum (or peak) concentration that a drug achieves in the body after the drug has been administrated.
