Provigil (Sparlon)

Teva Pharmaceutical Industries Ltd.

Drug Names(s): modafinil, Attenace, Modiodal (Japan), Vigil, Modasomil, CN-801, AFT-801

Description: The precise mechanism by which Provigil exerts its wake-promoting effects is still unclear. At pharmacologically relevant concentrations, it does not bind to or inhibit a number of receptors and enzymes potentially relevant for sleep/wake regulation. While Provigil-induced wakefulness can be attenuated by the alpha1-adrenergic receptor antagonist, prazosin, Provigil is inactive in other in vitro assay systems known to be responsive to alpha-adrenergic agonists. Provigil is not a direct- or indirect-acting dopamine receptor agonist, though it binds to the dopamine transporter and inhibits dopamine reuptake. However, there is conflicting evidence about the relevance of this.

Sparlon was the new formulation and dosage strength of modafinil, the active ingredient in Provigil Tablets, for ADHD, an indication that was suspended due to a potential side effect.
