Femoxetine (
INN; tentative brand name Malexil; developmental code name FG-4963) is a drug related to paroxetine that was being developed as an antidepressant by Danish pharmaceutical company Ferrosan in 1975 before acquisition of the company by Novo Nordisk. It acts as a selective serotonin reuptake inhibitor (SSRI). Development was halted to focus attention on paroxetine
instead, as femoxetine could not be administered as a daily pill.
Both femoxetine and paroxetine were invented in the 1970s. Jørgen Anders Christensen's name is on the patentspaper.[3]
After Ferrosan's acquisition, femoxetine died from neglect.[4]
In a separate patent, Ferrosan stated that Femoxetine could be used as an appetite suppressant,[5] using ten times the dosage than for paroxetine, 300 - 400mg daily.
Femoxetine has the same stereochemical properties as
Nocaine, another agent with a similar structure claimed to have been synthesized using arecoline as the starting alkaloid.[citation needed

Analogs
This section may be too technical for most readers to understand.(March 2022) |
- Addition of the para-fluoro atom results in a different compound that is a hybrid of femoxetine & paroxetine named FG 7080,[6] which has a separate patent.[7] According to the patent tables, incorporation of the fluorine atom potentiated the 5-HT affinity considerably.
- Pfizer made some similar analogs[8] E.g. a Viloxazine type of catechol ether is used, but 4-phenyl instead of based on a morpholine ring.
- NNC-63-0780.ORL1 instead of SERT.
- NNC 09-0026
