| Summary: | Psychotropic pharmacogenetics (PGx) offers significant potential advancements in psychiatric care by optimising medication selection and dosing based on genetic factors. This perspective article highlights the clinical utility, health economic implications and implementation challenges of psychotropic PGx, proposing that its broader implementation could enhance patient outcomes and reduce healthcare costs. Landmark studies show that PGx-guided care results in fewer adverse drug reactions and improved medication efficacy, with substantial cost savings compared to traditional prescribing methods. However, implementation barriers persist, particularly in Australia, where knowledge gaps, limited clinical guidelines and funding constraints hinder adoption. Despite challenges such as industry bias and limited data on non-antidepressant psychotropics, robust clinical and economic evidence supports the expanded use of psychotropic PGx, with emerging combinatorial approaches offering promise for future psychiatric treatment.
