Toward Multi-Omic–Informed Psychotropic Prescribing
Matching individuals to tolerable and efficacious pharmacotherapies in mental health has proven challenging. As such, efforts to personalize psychotropic prescribing in mental health has received considerable attention over the past decade. This attention has been fueled by technological advances in genomics, specifically, pharmacogenomics, and, more recently, epigenomics, transcriptomics, proteomics, and metabolomics that have facilitated the identification of clinically useful biological markers to guide medication selection and dosing. The convergence of these omic technologies is arguably the future of personalized psychotropic prescribing. This chapter provides an overview of the current genomic, epigenomic, transcriptomic, proteomic, and metabolomic knowledgebase as it relates to psychotropic drug response in an effort to identify promising linkages between and facilitate convergence across these approaches to guide safe and effective pharmacotherapy relevant to psychiatry.
