The main objective is to assess whether a novel electrochemical tool is reliable in detecting concentration of paracetamol in fingerprick- , saline-, urine-, and serum samples. We will recruit 12 healthy volunteers aged 18-45. They will get 1 g oral paracetamol. Paracetamol concentration will be detected from abovementioned samples at timely intervals for 24 hours, analyzed with the novel electrochemical method and compared to gold standard mass-spectrometry analysis. Despite of extensive use, the mechanism of action of parasetamol is not completely understood. The central serotonergic system may play a role. Endocannabinoid system is a group of lipid mediators, that possibly is involved in mediating paracetamol effect to the serotonergic system. Serum lipidomic assessment can be used to study endocannabinoid metabolics. In this study we will try to assess changes in endocannabinoid system by looking into serum lipidomics in order to understand the mechanism of action of paracetamol.

Comparison of Geometric Means of Cmax and AUC 0-last of Paracetamol Measured by the Novel Electrochemical Method With Mass-spectrometry in Capillary Whole Blood Samples.
Geometric mean values of the highest paracetamol concentrations (Cmax) and area under the curve (AUC) measured with the novel electrochemical method were compared with the 'gold standard' mass-spectrometry (control) from capillary whole blood samples. The data are presented as the ratio of geometric means to control, geometric coefficients of variation (as percentage) as a measure of dispersion.

Comparison of Geometric Means of Cmax and AUC 0-last of Paracetamol in Capillary With Venous Plasma (Control), Both Measured by Mass-spectrometry.
Geometric mean values of the highest paracetamol concentrations (Cmax) and area under the curve -calculations (AUC0-last) measured by mass-spectrometry were compared between capillary and plasma (control) to analyse paracetamol pharmacokinetics. The data are presented as ratio-to-control with geometric coefficients of variation (as percentage).
