Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
12 healthy participants will be randomly allocated, in a five-way cross-over manner, to the following treatments:
Treatment A: 650 mg paracetamol and 5 mg phenylephrine hydrochloride
Treatment B: 650 mg paracetamol and 5.2 mg phenylephrine hydrochloride
Treatment C: 650 mg paracetamol and 5.4 mg phenylephrine hydrochloride
Treatment D: 650 mg paracetamol and 5.6 mg phenylephrine hydrochloride).
Treatment E: 650 mg paracetamol and 5.8 mg phenylephrine hydrochloride
Each of the treatment will be administered orally, as a single dose. The administration of the study drugs is done under the supervision of the study staff.
There will be a washout period of 7 days between each of the study treatments
Participants will be required to fast overnight (for at least 10 hours) before dosing and for 4 hours thereafter.

Outcomes
Primary outcome [1] 295507 0
To determine and compare the pharmacokinetic parameters (Cmax, AUCt, AUCinf, Tmax) of different doses of phenylephrine hydrochloride (5-5.8 mg) when taken in combination with 650 mg paracetamol.
Timepoint [1] 295507 0
Plasma time concentrations will be determined from the blood samples collected at 5, 15, 30, 45 minutes and 1.00, 1.25, 1.50, 2.00, 3.00, 6.00, 8.00, 10.00 and 12.00 hours after each study drug administration.
Secondary outcome [1] 315723 0
To monitor the safety and tolerability of the different doses of phenylephrine hydrochloride (5-5.8 mg) when combined with 650 mg of paracetamol. This is a composite secondary outcome.

Safety will be assessed by assessing the frequency and percentage of adverse events.Changes from baseline (prior to dosing) of blood pressure and heart rate results will be compared between the treatment groups.
Timepoint [1] 315723 0
Safety will be evaluated during each study period and throughout the whole duration of the study
Vital signs will be measured pre-dosing and at 15, 30 minutes and at 1.00, 1.50, 2.00, 2.5, 3.0, 4.00, 8.00 and 12.00 hours after study drug administration.

Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Randomization will occur once participant eligibility is confirmed. Participants will be randomly assigned to one of the five possible study drug treatment sequences in a fashion that ensures: that each individual receives each treatment, that for each study period at least 12 participants are allocated to each treatment and that first-order carry-over effects are minimized. Each successive participant will receive a unique study identification number.
Allocation is done by contacting the holder of the allocation schedule who is located at the central administration site
Methods used to generate the sequence in which subjects will be randomised (sequence generation)

Summary
Brief summary
This is a Phase I pilot study designed to evaluate the pharmacokinetic profile of fixed dose combinations of paracetamol 325 mg, and phenylephrine hydrochloride at doses between 2.5 and 2.9 mg per tablet, when given as two tablets per dose. The results of this study will guide the selection of the further dose strength of phenylephrine hydrochloride to be used in a fixed dose combination with paracetamol 325 mg, which will be further evaluated in a larger confirmatory pharmacokinetic study.
