Pharmacogenetics is used in
psychiatry to predict the effects and side effects of
psychotropic drugs. As most
mental disorders have complex causes and unpredictable outcomes, personalized
treatment using
pharmacogenomics would be a useful
method. However,
pharmacogenetic studies in
psychiatry have yielded insignificant results thus far, making their clinical application extremely limited. Early testing, prediction of
drug side effects, and
drug compliance will be discussed as considerations for the
effectiveness of the pharmacogenetic test in
psychiatry. Although pharmacogenetic tests in
psychiatry do not yet have high
sensitivity and specificity, they may be useful in the
future for predicting clinical
prognosis or developing novel
drug treatments. As a result, the authors summarized the current
state and prospects of
pharmacogenetics in
psychiatry in this
review.
