OBJECTIVE: To examine the efficacy of atypical neuroleptics for decreasing craving and drug relapses during protracted withdrawal in individuals dually diagnosed with schizophrenia and cocaine dependence.
METHOD: We conducted a 6-week, open-label pilot study comparing risperidone with typical neuroleptics in a sample of withdrawn cocaine-dependent schizophrenia patients.
RESULTS: Preliminary results suggest that individuals treated with risperidone had significantly less cue-elicited craving and substance abuse relapses at study completion. Further, they showed a trend toward a greater reduction in negative and global symptoms of schizophrenia.
CONCLUSION: Atypical neuroleptics may help reduce craving and relapses in this population. Future research should include more rigorous double-blind placebo-controlled studies with this class of medications.
