Late-life depression is a kind of major depressive disorder which depressive symptoms occurs
after the age of 50-65 years. Approximately one-third of patients with late-life depression do not
respond to current used antidepressants. Therefore, translation of pharmacogenetic knowledge into
clinical practice in late-life depression may provide improving efficacy and reducing side effects of
antidepressants. Although the majority of researchs on pharmacogenetics of antidepressants have
been reported for the younger adults, genetic variations that influence antidepressant treatment in
late-life depression should be elucidated for identification of pharmacogenetic testing strategies.
This review covers articles investigating the effects of genetic polymorphisms on pharmacokinetics,
therapeutic response and advers drug reactions of antidepressants in late-life depression.

Yaşlılık çağı depresyonu, depresif semptomların 50-65 yaştan sonra ortaya çıktığı bir majör depresif
bozukluk türüdür. Yaşlılık çağı depresyonu hastalarının yaklaşık olarak üçte biri günümüzde kullanılan
antidepresanlara yanıt vermemektedir. Farmakogenetik bilginin klinik pratiğe aktarılması yaşlılık çağı
depresyonu hastalarında antidepresanların etkinliğinin artırılmasını ve yan etkilerinin azaltılmasını
sağlayabilir. Antidepresanların farmakogenetiği ile ilgili çalışmaların birçoğu genç erişkinlerde
yapıldığından, farmakogenetik test stratejilerinin belirlenmesi için yaşlılık çağı depresyonunda
antidepresan tedaviyi etkileyen genetik varyasyonların aydınlatılması gerekmektedir. Bu derleme
yaşlılık çağı depresyonunda genetik polimorfizmlerin antidepresanların farmakokinetiği, terapötik
yanıt ve advers ilaç reaksiyonları üzerindeki etkilerini araştıran makaleleri kapsamaktadır.
