Metabolite Identification
Common Namemodafinil acid
Descriptionmodafinil acid is a metabolite of modafinil. Modafinil is an analeptic drug invented in France by Lafon Laboratories and originally developed by neurophysiologist and emeritus experimental medicine professor Michel Jouvet. It is approved by the United States' Food and Drug Administration (FDA) for the treatment of narcolepsy, shift work sleep disorder and excessive daytime sleepiness associated with obstructive sleep apnea.
