BACKGROUND Emerging evidence indicates that NLRP3 inflammasome-induced inflammation plays a crucial role in the pathogenesis of depression. Thus, inhibition of NLRP3 inflammasome activation may offer a therapeutic benefit in the treatment of depression. Fluoxetine, a widely used antidepressant, has been shown to have potential antiinflammatory activity, but the underlying mechanisms remain obsc...

A growing body of evidence has indicated that energy metabolism impairment may be involved in pathophysiology of some neuropsychiatric disorders. In this study, we evaluated the effect of acute and chronic administration of fluoxetine, olanzapine and the combination of fluoxetine/olanzapine on citrate synthase activity in brain of rats. For acute treatment, Wistar rats received one single injec...

The effects of acute administration of fluoxetine, a selective serotonin reuptake inhibitor on spontaneous sleep, were studied in adult rats implanted for chronic sleep recordings. Fluoxetine was administered systemically or infused directly into the dorsal raphe nucleus (DRN), the right laterodorsal tegmental nucleus (LDT) or the medial pontine reticular formation (mPRF). Systemic administrati...

The aim of this study was to assess the effect of a combined 14-day treatment with rosuvastatin (10 mg/kg) and fluoxetine (10 mg/kg) on selected biochemical parameters of oxidative stress in the blood of rats. The activity of glutathione peroxidase (GPX), glutathione reductase (GR) and the total antioxidant status (TAS) were determined. A combined 14-day treatment with rosuvastatin and fluoxeti...

Serotonin (5-HT) acts as a neurotransmitter, but also modulates brain maturation during early development. The demonstrated influence of genetic variants on brain function, personality traits, and susceptibility to neuropsychiatric disorders suggests a critical importance of developmental mechanisms. However, little is known about how and when developmentally perturbed 5-HT signaling affects ci...

1. It has been reported that co-administration of fluoxetine with 3,4-methylenedioxymethamphetamine (MDMA, 'ecstasy') prevents MDMA-induced degeneration of 5-HT nerve endings in rat brain. The mechanisms involved have now been investigated. 2. MDMA (15 mg kg(-1), i.p.) administration produced a neurotoxic loss of 5-HT and 5-hydroxyindoleacetic acid (5-HIAA) in cortex, hippocampus and striatum a...

BACKGROUND The long elimination half-lives of fluoxetine and norfluoxetine, the active metabolite of fluoxetine, are of potential consequence when alternative antidepressant agents are introduced after the termination of fluoxetine therapy. It is not known whether paroxetine, an antidepressant agent in the same pharmacologic class as fluoxetine, can be substituted for fluoxetine without the nee...

Although Interferon-alpha (IFN-α) is a powerful drug in treating several viral infections and certain tumors, a considerable amount of neuropsychiatry side-effects such as depression and anxiety are unavoidable consequence. Combination with selective serotonin (5-HT) reuptake inhibitor (SSRI) fluoxetine significantly improved the situation. However, the potential 5-HT1A receptorand 5-HT1B recep...

The selective serotonin reuptake inhibitor fluoxetine significantly enhances adult visual cortex plasticity within the rat. This effect is related to decreased gamma-aminobutyric acid (GABA) mediated inhibition and identifies fluoxetine as a potential agent for enhancing plasticity in the adult human brain. We tested the hypothesis that fluoxetine would enhance visual perceptual learning of a m...
