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 patents[1][2] and Jorgen Buus-Lassen's name is on the pharmacology paper.[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[edit]
- 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.[9][10] binds to ORL1 instead of SERT.
- NNC 09-0026

Well, that’s interesting to know that Psilotum nudum are known as whisk ferns. Psilotum nudum is the commoner species of the two. While the P. flaccidum is a rare species and is found in the tropical islands. Both the species are usually epiphytic in habit and grow upon tree ferns. These species may also be terrestrial and grow in humus or in the crevices of the rocks.
