NCT02438072

Brief Summary

We propose here to explore systematically the association between drug-metabolizing enzymes activity assessed by a phenotypical approach and antidepressant plasma concentration, efficacy and tolerance in the clinical setting. During one year, patients receiving antidepressant will be included in tis prospective clinical, naturalistic and descriptive pilot study.

Drug: Omeprazole (10 mg, A02BC01)

Interventions

The cocktail of drug substrates will be given one time, one day during the study, to explore the activity of CYP 1A2, 2B6, 2C9, 2C19, 3A4, 2D6, and the P-gp
