Abstract
Objective: The antidepressant agomelatine agent is a melatonin receptor (MT1 and MT2) agonist and a serotonin receptor (5-HT2C) antagonist. Increasing evidence shows that agomelatine has neuroprotective and neuromodulatory effects. In this study, the potential effects of agomelatine in rats with scopolamine-induced cognitive impairment were investigated.
Özet
Amaç: Agomelatin, melatonin reseptör (MT1 ve MT2) agonisti ve serotonin reseptör (5-HT2C) antagonisti olan antidepresan bir ilaçtır. Artan kanıtlar, agomelatinin nöroprotektif ve nöromodülatör etkiye sahip olduğunu göstermektedir. Bu çalışmada skopolamin indüklü bilişsel yetmezlik oluşturulan sıçanlarda agomelatinin potansiyel etkileri araştırılmıştır.
