Bioequivalence Study of Sulfadoxine/Pyrimethamine 500/25 mg Dispersible Tablet
- Conditions
- Fasting
- Interventions
- Registration Number
- NCT06522763
- Lead Sponsor
- Swiss Pharma Nigeria Limited
- Brief Summary
The primary objective of this study is to assess the bioequivalence between the test product and the reference product based on Cmax and AUC0-\>72 for sulfadoxine and pyrimethamine in healthy adults under fasting conditions. The secondary objectives of present study are to describe the Tmax and assess the safety and tolerability profile of both test and reference products.

- Primary Outcome Measures
Name Time Method Area Under the plasma concentration-time Curve (AUC). 72 hours The confidence intervals of logarithmically transformed Test/Reference ratios for AUC are set to be within 80.00-125.00% for sulfadoxine and pyrimethamine. ANOVA using 5 % significance level on logarithmically transformed data (with the 90% confidence intervals) of AUC0-72 for sulfadoxine and pyrimethamine using WinNonLin statistical software version 8.4 or higher.
Maximal Plasma Concentration (Cmax). 72 hours The confidence intervals of logarithmically transformed Test/Reference ratios for Cmax are set to be within 80.00-125.00% for sulfadoxine and pyrimethamine. ANOVA using 5 % significance level on logarithmically transformed data (with the 90% confidence intervals) of Cmax and AUC0-72 for sulfadoxine and pyrimethamine using WinNonLin statistical software version 8.4 or higher.
- Secondary Outcome Measures
Name Time Method Time point of maximal plasma concentration (Tmax) To be determined within the 72 hours range Time of the maximum measured plasma concentration. If the maximum value occurs at more than one time point, Tmax is defined as the first time point with this value.
