Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Main Objective: The primary objective of this prospective clinical trial is to determine the pharmacokinetic variability of co-trimoxazole (960 mg) in patients receiving TB treatment. With these pharmacokinetic parameters, a population model and limited sampling model can be developed retrospectively.;Secondary Objective: The second objective is to calculate the AUC/MIC ratio and T>MIC and to validate drug concentration measurement using DBS by comparing the results of blood samples routinely withdrawn from venous blood versus withdrawn by finger prick and transferred to filter paper to make dried blood spots.;Primary end point(s): Determination of pharmacokinetic parameters of co-trimoxazole and the calculation of the bound and unbound AUC0-24h after administration of co-trimoxazole;Timepoint(s) of evaluation of this end point: On the 4th, 5th or 6th day. | — |
