Completed
- Conditions
- Healthy
- Interventions
- Drug: Aktren® 200 mg überzogene Tabletten (Ibuprofen)
- Registration Number
- NCT03694587
- Lead Sponsor
- Medherant Ltd
- Brief Summary
This is a Phase I study of the pharmacokinetics of a novel 200 mg Ibuprofen Medicated Plaster. The study will be conducted as a monocentric, open, randomised, single and multiple-dose, two-period, crossover trial in healthy volunteers. A total of 16 healthy volunteers will be randomised.
A wash-out period of 3 days is planned between the two periods. Each of the volunteers will be randomly assigned to one of 2 possible administration sequences.

- Primary Outcome Measures
Name Time Method AUC(0-12h) of ibuprofen 5 days Area under the concentration/time curve, from time 0 h to 12 h
AUC(0-t) of Ibuprofen 5 days Area under the concentration/time curve, calculated by the trapezoidal rule from time 0 h to last observed concentration at time t
Cmax of Ibuprofen 5 days Observed maximal concentration after administration
- Secondary Outcome Measures
Name Time Method Tmax after multiple dosing 5 days Observed time point of maximal concentration
t½ after multiple dosing 5days Plasma concentration half-life calculated according to t1/2=ln(2)/ λz
λz of total ibuprofen after multiple dosing 5 days Terminal rate constant (slowest rate constant of the disposition) negative of the slope of a log-linear regression of the unweighted data considering the last concentration-time points ≥ LLOQ
AUC(0-inf) after multiple dosing 5 days Area under the concentration/time curve, from time 0 h extrapolated to infinity (AUC(0-∞) = AUC(0-t) + Clast/λz where Clast is the last concentration above the limit of quantification and λz is the terminal elimination constant)
