  • Blood samples for Pharmacokinetic (PK) analyses: Predose (Baseline), and 0.5, 1, 2, 4, 6, 8, 12, 24, 48, 72, 96, 120 hours postdose
  • Urine samples for PK analyses: 0 - 6, 6 - 12, 12 - 24, 24 - 48, 48 - 72, 72 - 96, 96 -120 hours postdose

Patients with severe renal impairment (CLcr <30 mL/min/1.73 m^2). Subjects were orally administered Levetiracetam (LEV) 250 mg once. After LEV administration, safety assessments and blood and urine samplings were conducted through Day 7 during the Treatment Period, and safety follow-up assessments were performed on Day 8 according to the schedule of study assessments.

  • Blood samples for Pharmacokinetic (PK) analyses: Predose (Baseline), and 0.5, 1, 2, 4, 6, 8, 12, 24, 48, 72, 96, 120, 144 hours postdose
  • Urine samples for PK analyses: 0 - 6, 6 - 12, 12 - 24, 24 - 48, 48 - 72, 72 - 96, 96 -120, 120 - 144 hours postdose

Group E received Levetiracetam (LEV) 500 mg orally on Day 1, 44 hours (h) before the first hemodialysis. As a supplementary dose LEV 250 mg was administered 1 h after the end of the first hemodialysis on Day 3.

The 4-h Hemodialysis was scheduled as follows:

  1. Dialysis: 44 h to 48 h after the first dose (Day 3)
  2. Dialysis: 92 h to 96 h after the first dose (Day 5)
  3. Dialysis: 140 h after the first dose (Day 7)

Safety assessments and blood samplings were conducted until Day 7. Safety follow-up assessments were performed on Day 10.

Blood samples for Pharmacokinetic (PK) analyses: Predose (Baseline), and 0.5, 1, 2, 4, 6, 8, 12, 24, 30, 44*, 44.25*, 44.5*, 45*, 46*, 47*, 48*, 49, 49.5, 50, 51, 53, 55, 57, 61, 73, 92, 96, 120, 140 hours post first dosing.

49 h-sample was taken before the additional dose. The 44 h, 92 h, and 140 h samples were taken before the start of the hemodialysis.

*Inflow blood, outflow blood, and dialysate fluid were collected.
