General description

Fluoxetine hydrochloride is a psychotropic agent and one of the initial members of the anti-depressant class of drugs known as selective serotonin-reuptake inhibitors (SSRIs). It is the active ingredient of Prozac®.


Fluoxetine hydrochloride has been used to study its effect on the binding ability of the radiopharmaceutical 123I-labeled 2-((2-((dimethylamino)methyl)phenyl)thio)-5-iodophenylamine ([123I]ADAM) to SERT (serotonin transporters) in mice. It has also been used for the chronic treatment of light deprived animals.


10, 50 mg in poly bottle

Biochem/physiol Actions

Fluoxetine hydrochloride is a selective serotonin reuptake inhibitor and functions as an antidepressant. This drug works at presynaptic terminals where it prevents the reuptake of serotonin, resulting in the accumulation of serotonin in extracellular fluid at synapses.
Selective serotonin reuptake inhibitor; antidepressant.

A radiopharmaceutical, (123)I-labeled 2-((2-((dimethylamino)methyl)phenyl)thio)-5-iodophenylamine ([(123)I]ADAM), has been developed recently for evaluation of how serotonin transporters (SERT) function in the brain. However, the detailed biodistribution and specific binding in certain brain areas are not well investigated. In this study, both phosphor...
