Cocaine addition definition

Dopamine-Stimulating Medications. A variety of drugs that increase the availability of dopamine have been studied in cocaine addicts including L-DOPA, bupropion, amantadine, and methylphenidate. In small uncontrolled trials, these have shown some benefit, but definitive studies have yet to be performed. In addition, some dopamine-stimulating medications (in particular, the stimulants like methylphenidate or the amphetamines) are themselves subject to abuse, though, of note, this is typically not a problem when they are prescribed to patients who do not have a history of substance abuse such as, for example, in the treatment of attention deficit-hyperactivity disorder.
