Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Each participant will be randomly allocated to receive a single dose of each of the following treatments in a balanced three-way cross-over sequence:
Treatment A: 975 mg acetaminophen and 292.5 mg ibuprofen
Treatment B: 650 mg acetaminophen and 75 mg tramadol hydrochloride
Treatment C: 800 mg ibuprofen.
All treatments will be administered as oral tablets, with a full glass of water, in fed conditions. The administration of all doses will be supervised on site. The washout period between the periods is 3 days.
Dose frequency - single dose, administered as oral tablets.
All participants complete all three periods (treatments A-C) in a cross-over fashion.
Participants will be fasted for at least 10 hours overnight before dosing and receive a standardized breakfast served 30 minutes prior to study drug administration. This breakfast will supply around 967kcal about 50% of which are fat calories. A standardized meal will be provided approximately at 5 hours after dosing. Also a snack will be provided approximately at 9 hours after the study drug administration. Meal plans will be identical in all periods and will be served at the same time. Water will be restricted for 1 hour pre-dose and 1 hour post-dose.

Outcomes
Primary outcome [1] 297600 0
To determine and compare dose-normalized acetaminophen and ibuprofen related pharmacokinetic parameters (Cmax,AUC(0-t), AUC(0-inf), Tmax, t1/2)betweeen all treatment groups, under fed conditions
Timepoint [1] 297600 0
Single dose study measuring plasma concentration pre-dose and at 10, 20,30,45 minutes and at 1,1.25,1.50,2,2.5,3,4,6,8,10 and 12 hours after study drug administration.
Secondary outcome [1] 321555 0
Safety will be evaluated during each study period and for 7 days following last dose of study drug administration. An acute safety evaluation will be performed during each study period by recording spontaneously reported adverse events and by clinical assessments.
Known NSAID adverse events (i.e gastrointestinal ulceration, indigestion, stomach pain, GI bleeding, bronchospasm, water retention, renal failure, skin reactions and thromboembolic events)and known acetaminophen adverse effects (i.e.clinical evidence of hepatotoxicity) will be summarized by treatment groups. Adverse events will continue to be assessed up to 7 days after the last dose of the study medication by spontaneous reporting and a final follow-up call.
Timepoint [1] 321555 0
Safety will be evaluated during each study period (from administration to 12 hours post administration) at Days 1, 4, 6 and for 7 days following study drug administration.
