The present and the future of pharmacogenetic testing with focus on the pharmacotherapy of depression

The paper deals with possibilities of pharmacogenetic testing in psychiatry. The greatest progress has been made in depressive disorder. Several expert groups and professional associations specialize on developing guidelines for pharmacogenetics testing. Consensus and high level of evidence have been achieved in genotyping of P450 CYP2D6 and CYP2C19 enzymes. It was found that their activity is associated with efficacy and tolerability of many drugs. Nowadays, the multigenes, mostly commercially produced tests, are becoming important. They can help with choice and adequate dosing of drug in individual patient. Undoubtedly, the pharmacogenetics will play an important role in optimization and individualization of treatment in psychiatry and we should include this topic into life long education in psychiatry.
