Primary Outcome Measures
NameTimeMethod
to evaluate the effect of steady-state ucb 34714 administration on the steady-state plasma levels of phenytoin.
Blood samples for PK calculations collected at different time points, on Visit 2 and Visit 7, for determination of phenytoin plasma concentrations (Phenytoin levels at pre-dose, 1, 2, 4, 6, 8, 12 (24 if PHT od) hours at V2 and V7)
The drug interaction on phenytoin will be assessed by comparison of AUCτ and Cmax between Visit 2 (phenytoin alone) and Visit 7 (combination of ucb 34714 and phenytoin).
Secondary Outcome Measures
NameTimeMethod
information on the tolerability and safety of the simultaneous administration of ucb 34714 and phenytoin in epilepsy patients.
