Fladrafinil
Fladrafinil, also known as fluorafinil or as bisfluoroadrafinil, is a wakefulness-promoting agent related to modafinil that was never marketed. It is sold online and used non-medically as a nootropic.
Modafinil and its analogues are known to act as dopamine reuptake inhibitors and this is thought to be involved in their wakefulness-promoting effects. Chemically, fladrafinil is a derivative of adrafinil and is also known as bisfluoroadrafinil. It is closely related to flmodafinil.
