It is counted among a popular section of compounds known as Nootropics. Because of its ability to improve memory, learning ability and a host of various other cognitive processes, it is also referred to as the smart drug. This drug was initially launched to treating the lack of alertness, strength found among people who suffering from insomnia, sleep disorders etc.

This drug was at one time also being considered for treatment of ADHD. However, the FDA has stopped that because they found that the drug was not appropriate for children. Because this drug is popular for its ability to keep people alert it is used for the treatment of conditions like sleeping for extensive periods during the day, sleeping disorders, narcolepsy etc. Various countries have various trade names for this drug like Alertec, Provigil, and Modavigil. USHA categorizes this drug as a schedule IV controlled substance and hence it cannot be obtained easily. Other countries require a prescription for buying this drug. Another trade name for this drug is Bravamax.
