| Sequence Brivaracetam (BRV) Tablet - BRV Dry Syrup Dosing period 1 consisted of 5 days (Day -1 \[1 day before administration of IMP\] to Day 4): On Day 1 and Day 2 each participant received a dose of BRV 50 mg tablet formulation twice daily; on Day 3, each participant received a single morning dose of BRV 50 mg tablet formulation. Dosing period 2 consisted of 5 days (Day -1 \[1 day before administration of IMP\] to Day 4): On Day 1 and Day 2 each participant received a dose of BRV 50mg as dry syrup twice daily; on Day 3, each participant received a single morning dose of BRV 50 mg as dry syrup. The final IMP administration in Dosing Period 1 and the first investigational medicinal product (IMP) administration in Dosing Period 2 were separated by a washout period of 6-10 days. | 32 |
