Modafinil’s Story

Modafinil was first developed at Lafon Laboratories in France in the late 1980’s. Modafinil was discovered after the invention of a chain of other chemicals categorized as Benzhydryl Sulfinyl. Most importantly, these included Modafinil’s precursor compound Adrafinil. Adrafinil was first found to improve wakefulness & alertness, later it was offered to treat people suffering from Narcolepsy in 1986 in France.

Modafinil was discovered as primary Metabolite and active component for Adrafinil. It was observed that Modafinil had lesser side effects & greater potency than its precursor. Although the use of Modafinil has grown exponentially in countries like UK and US, Adrafinil is used as a substitute to Modafinil as the drug is available without a prescription. Modafinil has been sold in United states from 1998, under the name Provigil, which is distributed by Cephalon Inc (The parent company of Lafon from 2001).

Although some other medical conditions were found to benefit from Modafinil, FDA has failed to identify any additional benefits, even til this day.

Many studies were conducted and demonstrated how Modafinil can be used in treating ADHD in children and adults while carrying very few side effects, addiction, withdrawal or abuse when compared with similar drugs like Adderall or Ritalin. There were negative reactions in children aged 7 to 12 in about 20 of 100 patients, and for this reason the FDA Advisory committee in a vote of 12 to 1 decided that Cephalon would not be allowed to create the drug Sparlon (Modafinil in 345mg to 420mg doses) which was to be used for ADHD in children — which also happens to be the dose that Cephalon considered to be the “effective” dose in treating ADHD.
