Complementary Combination Therapy for Cocaine Dependence

Summary

The investigators will assess the impact of treatment with doxazosin and modafinil, alone and in combination, on the subjective and reinforcing effects of cocaine in non-treatment-seeking, cocaine-dependent volunteers. The investigators will use a hybrid design in which participants will be randomized into two groups: placebo and doxazosin 8 mg/d. They will remain in their assigned group for the duration of the study. After titrating doxazosin to the target dose, study procedures will be completed three times, once during treatment with each dose of modafinil (0, 200, and 300 mg/d), in pseudo-random order such that 200 mg precedes 300 mg).
