Genetic testing that helps doctors select suitable antidepressants for patients did not lead to better improvements in depressive symptoms than standard prescriptions based on clinical guidelines, according to a clinical trial conducted in Australia by an international team of researchers.
The NTU-led study contrasts with previous findings that using a patient's genetic information to personalise antidepressant treatment leads to better outcomes.
The researchers say their observations suggest that a greater understanding of which patients are most likely to benefit from pharmacogenomic-informed prescribing is required before recommending it for routine use.
