Biological Activity

Description

Fluoxetine HCl is a selective serotonin-reuptake inhibitor (SSRI) at the neuronal membrane, used in the treatment of depression.

Targets

5-HT ^[1]

In vitro
In vitro	Fluoxetine blocks the downregulation of cell proliferation resulting from inescapable shock (IS) of hippocampal cell. ^[1] Fluoxetine increases the number of newborn cells in the dentate gyrus of the hippocampus of adult rat. Fluoxetine also increases the number of proliferating cells in the prelimbic cortex. ^[2] Fluoxetine accelerates the maturation of immature neurons. Fluoxetine enhances neurogenesis-dependent long-term potentiation (LTP) in the dentate gyrus. ^[3] Fluoxetine, but not citalopram, fluvoxamine, paroxetine and sertraline, increases norepinephrine and dopamine extracellular levels in prefrontal cortex. Fluoxetine produces robust and sustained increases in extracellular concentrations of norepinephrine and dopamine after acute systemic administration. ^[4]
Cell Research	Cell lines	MDA-MB-231 cells
	Concentrations	1 µM
	Incubation Time	24 h
	Method	Cells were treated with indicated concentrations of drug for 24 h.

In Vivo
In vivo	Fluoxetine treatment also reverses the deficit in escape latency observed in animals exposed to inescapable shock in adult male Sprague–Dawley rats. ^[1] Fluoxetine combined with Olanzapine produces robust, sustained increases of extracellular levels of dopamine ([DA](ex)) and norepinephrine ([NE](ex)) up to 361% and 272% of the baseline, respectively, which are significantly greater than either drug alone. ^[5]
Animal Research	Animal Models	Male Sprague-Dawley rats
	Dosages	10 mg/kg
	Administration	s.c.
