Effectiveness of Modafinil and D-amphetamine in Treating Cocaine Dependent Individuals
Cocaine dependence is a major public health problem; an effective primary treatment for cocaine dependent individuals has yet to be found. The purpose of this study is to examine the effects of d-amphetamine and modafinil, when given alone and in combination, in treating cocaine dependent individuals.
Cocaine is a strong central nervous system stimulant that is widely abused throughout the United Sates. Due to its widespread use, it is important to develop an effective treatment for cocaine dependence. Modafinil is a glutamate-enhancing agent. D-amphetamine is a central nervous system stimulant that is approved to treat individuals with narcolepsy and attention deficit disorder. Both modafinil and d-amphetamine may be effective treatments for cocaine dependence. The purpose of this study is to examine the effectiveness of modafinil and d-amphetamine, alone and in combination, in treating cocaine dependent individuals.
This study will last 16 weeks. Participants will be randomly assigned to one of four groups: 1) 200 mg dose of modafinil; 2) 400 mg dose of modafinil; 3) 30 mg dose of d-amphetamine combined with 200 mg dose of modafinil; and 4) placebo. All participants will receive 200 mg of modafinil over 4 days. Participants assigned to the 400 mg modafinil treatment group will then receive double the initial dose of modafinil for the duration of the study. Participants in the combined group (modafinil and d-amphetamine) will receive 15 and then 30 mg of d-amphetamine over 4 days.

Medical and Biotech [MESH] Definitions
Tricyclic anorexigenic agent unrelated to and less toxic than AMPHETAMINE, but with some similar side effects. It inhibits uptake of catecholamines and blocks the binding of cocaine to the dopamine uptake transporter.
Derivatives of chondroitin which have a sulfate moiety esterified to the galactosamine moiety of chondroitin. Chondroitin sulfate A, or chondroitin 4-sulfate, and chondroitin sulfate C, or chondroitin 6-sulfate, have the sulfate esterified in the 4- and 6-positions, respectively. Chondroitin sulfate B (beta heparin; DERMATAN SULFATE) is a misnomer and this compound is not a true chondroitin sulfate.
The purified, alkaloidal, extra-potent form of cocaine. It is smoked (free-based), injected intravenously, and orally ingested. Use of crack results in alterations in function of the cardiovascular system, the autonomic nervous system, the central nervous system, and the gastrointestinal system. The slang term "crack" was derived from the crackling sound made upon igniting of this form of cocaine for smoking.
An enzyme that catalyzes the activation of sulfate ions by ATP to form adenosine-5'-phosphosulfate and pyrophosphate. This reaction constitutes the first enzymatic step in sulfate utilization following the uptake of sulfate. EC 220.127.116.11.
An arylsulfatase that catalyzes the hydrolysis of the 4-sulfate groups of the N-acetyl-D-galactosamine 4-sulfate units of chondroitin sulfate and dermatan sulfate. A deficiency of this enzyme is responsible for the inherited lysosomal disease, Maroteaux-Lamy syndrome (MUCOPOLYSACCHARIDOSIS VI). EC 18.104.22.168.
