Measure
Test (Tramadol HCl OAD 200 mg) First
1 x 200 mg Tramadol OAD (Once-A-Day) Tablet Daily test product dosed in first period followed by Tramadol IR (Ultram®) 50 mg 6-hourly) reference product dosed in the second period. The two treatment phases each started with a run-in period of 4 days (Days 1 to 4), a profile period and clinic stay of 3 days (Days 5 to 7) (clinic days and observation period) and a drug-free period of 16 days between treatment phases (Day 7 of Treatment phase I until Day 1 of the run-in period of Treatment phase II).
Reference (Trazodone IR (Desyrel®) 100 mg 8-hourly) First
1 x 100 mg Trazodone HCl IR (Desyrel®) Tablet 8-Hourly reference product dosed in first period followed by Trazodone OAD (Once-A-Day) Tablet Daily test product dosed in the second period. The two periods were separated by a washout of at least 7 calendar days. IR = Immediate Release.

SECONDARY outcome

Timeframe: 24 hours (day 5)

Percentage peak-trough fluctuation over 24 hours (24h) at steady state on day 5. Percent peak-to-trough fluctuation is calculated as (Cmax - Cmin)/Cav\*100, where Cmax is the maximum observed concentration, Cmin is the minimum observed concentration and Cav is the average concentration over 24 hours (where Cav = AUCss/24).

SECONDARY outcome

Timeframe: 24 hours (day 5)

Percentage swing is a pharmacokinetic parameter recommended by the FDA for submission and is calculated as follows:((Cmax,ss - Cmin,ss)/Cmin,ss)\*100. It was calculated over 24 hours on day 5. Where: Cmax,ss = Maximum concentration at steady state; Cmin,ss = Minimum concentration at steady state.
