• Status: Completed
• Trial end date: 2021-03-14
• Target enrollment: 0
• Participant gender: All

Summary

The objective of the study is to compare the pharmacokinetic profile of riluzole after replicate single dose of the novel orodispersible film test formulation and of the marketed reference Rilutek® tablets and to evaluate their bioequivalence.

The subjects will receive single oral doses of 50 mg of riluzole, as test orodispersible film and reference film-coated tablets under fasting conditions, in each of 4 subsequent periods separated by wash-out intervals of at least 7 days between consecutive administrations, according to a 2-treatment, 4-period, replicate cross-over design.
