Placebo Effect of Paracetamol in Healthy Volunteers (HOP)
Paracetamol is one of the most commonly used drugs in the world, indicated for the symptomatic treatment of fever and pain of mild to moderate. More precisely, it is a drug used to relieve pain and reduce fever. The objective of this study is to analyze whether a placebo effect occurs when you take paracetamol for pain, ie if the analgesic effect of paracetamol is partly due to the simple fact of taking a drug.
Moreover, during the study you propose to do a saliva sample, optional, for biological research, pharmacogenetics, to assess how paracetamol is processed and eliminated in your body..
