Primary Outcome Measures
NameTimeMethod
This is a composite primary outcome to compare the bioavailability of paracetamol, ibuprofen and doxylamine (as summarised by Cmax and AUC) for all formulations. All plasma samples will be assayed for paracetamol, ibuprofen and doxylamine using one fully validated LC/MS/MS method. Validation will be conducted to comply with EU and FDA guidelines. Codeine phosphate will not be analysed in this study.[Prior to dosing and at 10 min, 20 min, 0.5, 0.75, 1, 1.25, 1.5, 2, 2.5, 3, 3.5, 4, 4.5, 5, 6, 8, 10, 12, 14, 16, 20, 24, 36 and 48 hours post dosing.]
Secondary Outcome Measures
NameTimeMethod
This is a composite secondary outcome measuring Time to maximum peak concentration (Tmax) for paracetamol, ibuprofen and doxylamine combined in one assay. Tmax will be the time where the maximum concentration occurred in the sample points. [Prior to dosing and at 10 min, 20 min, 0.5, 0.75, 1, 1.25, 1.5, 2, 2.5, 3, 3.5, 4, 4.5, 5, 6, 8, 10, 12, 14, 16, 20, 24, 36 and 48 hours post dosing.]
