Brief summary
Randomized, open label, single dose, 4-way crossover study to investigate the bioequivalence of a new fixed dose combination tablet of nifedipine GITS and candesartan with the corresponding loose combination and to compare it with the individual drugs
Interventions
Single dose of 1 FDC tablet consisting of 60 mg nifedipine GITS and 32 mg candesartan
Single oral dose of 1 tablet of nifedipine GITS 60 mg
Single oral dose of 32 mg (2 x 16 mg tablet) candesartan

Design outcomes
Primary
| Measure | Time frame | Description |

Secondary
| Measure | Time frame | Description |
|---|---|---|
| AUCnorm | Within 48 hours after each treatment | Area under the curve divided by dose per kg body weight for nifedipine and candesartan |
| AUC(0-48) | Within 48 hours after each treatment | AUC from time 0 to time 48 h for nifedipine and candesartan |
| tmax | Within 48 hours after each treatment | Time to reach maximum drug concentration in plasma after single (first) dose for nifedipine and candesartan |
| AUC | Within 48 hours after each treatment | Area under the plasma concentration vs time curve from zero to infinity after single (first) dose for nifedipine and candesartan |
| MRT | Within 48 hours after each treatment | Mean residence time for nifedipine and candesartan |
| CL/f | Within 48 hours after each treatment | Total body clearance of drug from plasma calculated after oral administration (apparent oral clearance) for nifedipine and candesartan |
| Number of participants with adverse events | Approximately 3.5 months | — |
| t½ | Within 48 hours after each treatment | Half-life associated with the terminal slope for nifedipine and candesartan |
| Cmax,norm | Within 48 hours after each treatment | Maximum drug concentration in plasma after dose administration divided by dose (mg) per kg body weight for nifedipine and candesartan |
