BACKGROUND Previous literature has found fluoxetine to be relatively safe in overdose. This study hopes to examine this idea along with support from published pharmacokinetic information including serum fluoxetine and norfluoxetine levels based on information from a clinical case series. METHODS Four cases are presented along with vital abnormalities, electrocardiogram abnormalities, and phys...
Neuronal plasticity peaks during critical periods of postnatal development and is reduced towards adulthood. Recent data suggests that windows of juvenile-like plasticity can be triggered in the adult brain by antidepressant drugs such as Fluoxetine. Although the exact mechanisms of how Fluoxetine promotes such plasticity remains unknown, several studies indicate that inhibitory circuits play a...
We have recently shown that chronic fluoxetine treatment acted significantly increasing plasma norepinephrine and epinephrine concentrations both in control and chronically stressed adult male rats. However, possible effects of fluoxetine on catecholamine synthesis and re-uptake in adrenal medulla have been largely unknown. In the present study the effects of chronic fluoxetine treatment on tyr...
We isolated two mutants defective in the uptake of exogenous serotonin (5-HT) into the neurosecretory motor neurons of Caenorhabditis elegans. These mutants were hypersensitive to exogenous 5-HT and hyper-responsive in the experience-dependent enhanced slowing response to food modulated by 5-HT. The two allelic mutations defined the gene mod-5 (modulation of locomotion defective), which encodes...
A series of fluoxetine, where the N-methylamino group was replaced and then simplified, were synthesized and their inhibitory effect was tested for nitric oxide (NO) production and inducible NO synthase (iNOS) expression in lipopolysaccharide (LPS)-induced BV2 cells. Although the synthesized compounds generally revealed weaker activity or greater cytotoxicity than fluoxetine, compound 10a, in w...
The anorexic agents dexfenfluramine and fenfluramine plus phentermine have been associated with outbreaks of pulmonary hypertension. The fenfluramines release serotonin and reduce serotonin reuptake in neurons. They also inhibit potassium current ( I K), causing membrane potential depolarization in pulmonary arterial smooth muscle cells. The recent withdrawal of the fenfluramines has led to the...
There is evidence that angioplasty-induced vasospasm is mediated by serotonin (5-hydroxytryptamine [5-HT]) release from platelets. We tested the hypothesis that pretreatment of the atherosclerotic rabbit with fluoxetine, a platelet-uptake inhibitor of 5-HT, would reduce vasospasm after balloon angioplasty. Short-term administration of fluoxetine reduced platelet 5-HT uptake to 4% of baseline. D...
Selective serotonin reuptake inhibitors may be associated with new adverse events after abrupt discontinuation. Hypothesizing that the long half-life of fluoxetine would be protective, this study analyzed the effects of abrupt fluoxetine discontinuation during a randomized, double-blind, placebo-controlled study of depression maintenance treatment. After 12 weeks of fluoxetine treatment (20 mg/...
OBJECTIVE To assess the efficacy and tolerability of fluoxetine for the acute treatment of children and adolescents with generalized anxiety disorder, separation anxiety disorder, and/or social phobia. METHOD Anxious youths (7-17 years old) who had significant functional impairment were randomized to fluoxetine (20 mg/day) (n = 37) or placebo (n = 37) for 12 weeks. RESULTS Fluoxetine was ef...
Fluoxetine ameliorates cartilage degradation in osteoarthritis by inhibiting Wnt/β-catenin signaling
Abnormal activation of the Wnt/β-catenin signaling is implicated in the osteoarthritis (OA) pathology. We searched for a pre-approved drug that suppresses abnormally activated Wnt/β-catenin signaling and has a potency to reduce joint pathology in OA. We introduced the TOPFlash reporter plasmid into HCS-2/8 human chondrosarcoma cells to estimate the Wnt/β-catenin activity in the presence of 10 μ...
