The article discusses the current state of the use of pharmacogenetic testing in clinical practice in the field of psychiatry, narcology and neurology in the Russian Federation. The active introduction of pharmacogenetic testing in clinical practice contributes to a personalized approach to predicting the pharmacological response to drugs, increasing the safety and effectiveness of pharmacotherapy, complience and the quality of life of patients with neuropsychiatric disorders. In the future, an increase in the availability of pharmacogenetic testing in real clinical practice is expected.
There is a number of antidepressants (ADs) which prevent reabsorption of neurotransmitters in the body. Known together as reuptake inhibitors, they prevent the reuptake of one or some neurotransmitters so that the majority of them is present and active in the brain. Selective serotonin reuptake inhibitors (SSRIs) work at the expense of specific inhibition of serotonin reuptake. Such new SSRIs fluoxetine (FXT), are effective for treatment of depressive disorders in most cases of schizophrenia. The effectiveness of SSRIs is not immediate; therefore, medication can take up to several weeks to be fully effective. FXT is one of the top ten prescribed antidepressants. FXT is prescribed in cases of depressive disorders in adults and adolescents [1], obsessive-compulsive and anxiety-depressive disorders [2], as well as for the therapy of bulimia nervosa [3]. Pharmacogenetic markers of FXT safety are being actively studied. Some pharmacogenetic markers of therapy safety have been established: genes of serotonin receptor isoforms and its transporters (HTR1A, HTR1B, SCL6A4).
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
