Norfluoxetine is an active N-desmethyl metabolite of the antidepressant fluoxetine that inhibits serotonin uptake. Norfluoxetine is selective serotonin reuptake inhibitor (SSRI) but little is known about its pharmacological actions. Seproxetine (S- Norfluoxetine) was being investigated by Eli Lilly as an antidepressant but development was never completed and the drug was never marketed.

Sample Use Guides

In Vivo Use Guide

Rats were treated with Norfluoxetine (0-20mg/kg)

Route of Administration: Other

In Vitro Use Guide

Rat cortical membranes equivalent to 50 mkg of protein were incubated at 37°C for 30 minutes in 2 ml of reaction medium containing the Norfluoxetine (1-1000nM), 0.1 nM [3Hlparoxetine, 50 mmol/L Tris-HG, pH 7.4, 150 mmol/L NaG, and 5 mmol/L KCl. Fluoxetine at 1 mkM/kg was used to determine nonspecific binding
