psychopharmacogenomics
The study of how genetic variations affect individual responses to psychiatric medications, informing personalized treatment approaches.
Full Definition
Psychopharmacogenomics is the branch of pharmacogenomics that examines how genetic differences influence individual responses to psychiatric medications, including efficacy, side effects, and metabolism. This field studies genetic polymorphisms affecting drug-metabolizing enzymes (particularly cytochrome P450), neurotransmitter receptors, and drug transporters. Clinical applications include genetic testing to guide medication selection, predict adverse reactions, and optimize dosing for psychotropic drugs. Common tests examine CYP2D6 and CYP2C19 enzyme variants that affect metabolism of antidepressants, antipsychotics, and other psychiatric medications, potentially improving treatment outcomes while reducing trial-and-error prescribing.
Usage
Usage note: Distinguish from general pharmacogenomics; emphasize psychiatric medication focus.
In Context
- "Psychopharmacogenomics testing revealed the patient was a poor metabolizer of CYP2D6 substrates, explaining the adverse effects." — Genetic testing interpretation
- "The clinic implemented psychopharmacogenomics protocols to reduce antidepressant treatment failures." — Quality improvement initiative
