Comparator / control treatment
Comparator 1:
Maxigesic as a single oral dose of two tablets (total dose paracetamol 1000mg and ibuprofen 300mg).
Comparator 2:
Phenylephrine as a single oral dose of two tablets (total dose phenylephrine 10mg).
Control group

Primary outcome [1] 287712 0
To describe the pharmacokinetics of Maxigesic PE and identify whether a pharmacokinetic interaction exists between phenylephrine and paracetamol or ibuprofen when given concomitantly.

This will be assessed by taking blood samples which will be assyed for paracetamol, ibuprofen and phenylephrine concentrations and the pharmacokinetic parameters AUC0-inf, AUC0-t, Cmax, Ke, Tmax and T1/2 will be determined. These pharmacokinetic parameters will be compared between groups.
Timepoint [1] 287712 0
Blood samples will be collected pre-dose and at 5, 15, 30, 45 minutes and 1, 1.25, 1.5, 2.0, 3.0, 6.0, 8.0, 10.0 and 12.0 hours after study drug administration.
Secondary outcome [1] 298679 0
To examine the safety and tolerability of Maxigesic PE.

Safety will be evaluated during each study period, and for 7 days following study drug administration. Acute safety evaluations will be performed during each study period by recording spontaneously reported AE's and by clinical assessments (incl. heamatology & biochemistry).

Known NSAID adverse effects (i.e. GI ulceration, indigestion/stomach pain, GI bleeding, bronchospasm, water retention, renal failure, skin reactions and thromboembolic events), known paracetamol adverse effects (i.e. clinical evidence of hepatotoxicity) and known phenylephrine adverse effects (i.e. bradycardia, hypertension) will be compared between groups.
Timepoint [1] 298679 0
Adverse event reporting will be by spontaneous reporting up to 7 days after dosing, and by a follow up phone call 7 days after the last dose of the study medication.
