Authors' objectives: Genetic testing for predicting response and / or tolerance to treatment with antidepressant are based on the identification of genes associated with cytochrome P450, mainly CYP2D6 and CYP2C19, which allows to classify patients according to their ability to metabolize (poor, intermediate, extensive and ultrarapid). Alpha A systematic review was conducted in order to assess the effectiveness of genetic tests to predict response to antidepressant treatment and the occurrence of adverse events.
Authors' recomendations: The selected documents were a Elath technology report, two systematic reviews and seven original articles (three cohort studies and four case-control studies) The main methodological limitation was the high risk selection bias. No association between metabolizer profiles and treatment response except in of the studies, in which patients classified as intermediate metabolizers had a remission faster than the rest. In terms of tolerance, only one of the three studies that offered this outcome found an increased risk of a change in treatment among users of tricyclic antidepressants (OR = 5.77, 95% CI 1.59 to 21.03, p = 0.01). This risk was higher in poor metabolizers than in extensive. However, it was found that the dose of drug required was higher in poor metabolizers.
