Primary outcome [1] 288869 0
Evaluation of Pharmacokinetic paramaters [Cmax, AUC, Tmax, T 1/2] of Phenylephrine hydrochloride
Assessed by measurement of plasma drug concentrations
Timepoint [1] 288869 0
Single dose study measuring plasma concentrations over 5, 15, 30, 45 minutes and 1, 1.25, 1.5, 2, 3, 6, 8, 10 and 12 hours after study drug administration.
Secondary outcome [1] 301203 0
Safety will be evaluated during each study period, and for 7 days following study drug administration.
An acute safety evaluation will be performed during each study period by recording spontaneously reported adverse events and by clinical assessments, including measurements of blood pressure and heart rate.

Known phenylephrine hydrochloride adverse effects (i.e increased systolic and diastolic blood pressure, palpitations, headache, vomiting, nervousness), and known paracetamol adverse effects (i.e. clinical evidence of hepatotoxicity) will be compared between groups.
Adverse events will continue to be assessed up to 7 days after the last dose of the study medication by spontaneous reporting and at a final follow-up phone call.
Timepoint [1] 301203 0
Single dose study measuring plasma concentrations over 5, 15, 30, 45 minutes and 1, 1.25, 1.5, 2, 3, 6, 8, 10 and 12 hours after study drug administration.
Primary outcome is derived from the plasma-time AUC values over this entire time period
