Modafinil and Cocaine


This Phase I trial evaluated the interaction between modafinil steady-state and cocaine. Twelve non-treatment seeking, cocaine dependent volunteers received four sets of randomized blinded infusions of saline, 20 mg IV cocaine, and 40 mg IV cocaine. Modafinil was given open label at 0 mg, 400 mg, or 800 mg. Modafinil combined with IV cocaine did not result in any significant hemodynamic interactions. Modafinil significantly dampened scores on Visual Analog Scale measures as compared to baseline cocaine conditions. No significant alterations in labs occurred. Further outpatient trials of modafinil appear to be warranted.
