Evaluation of the Relevance of Pharmacogenetics in the Prescription Off Antidepressants in a Military Population

The treatment of depression, anxiety disorders and post-traumatic stress disorder (PTSD) is a main public health problem due to the frequency of these pathologies and the very partial effectiveness of the existent therapies. These illnesses generally require the prescription of several successive lines of antidepressant treatments before the treatments actually become effective, leading to a several week delay during which the patient suffers from the symptoms of his/her pathology and is also likely to experience the side effects of the treatment. Pharmacogenetics is an individualized prescribing modality that aims to predict the most favorable treatment for a given individual based on the study of genetic variants of cytochromes. The main hypothesis of this research is that the use of pharmacogenetics in routine practice in a population of military personnel requiring a first prescription of an antidepressant is of interest to improve the tolerance and effectiveness of the treatment.
