Objective: The objective of this selective EBM review is to determine whether or not the use of oral amphetamines reduces cocaine use in cocaine-dependent individuals.

Study Design: Review of three English language randomized control trials (RCTs) published in 2001, 2003 and 2004.

Data Sources: 3 randomized controlled trials published after 1999 were obtained using PubMed, OVID, and Medline.

Outcomes Measured: The efficacy of using d-amphetamine to promote cocaine use cessation in cocaine-dependent individuals, determined using immunoassay and mass spectrometric analysis to identify cocaine metabolites in the participant’s urine.

Results: Grabowski et al (2004) found a significant reduction in the use of cocaine in cocaine-dependent individuals, while Grabowski et al (2001) and Shearer et al were unable to show a significant reduction.

Conclusion: Evidence supporting the role of oral amphetamines in reducing cocaine use in cocaine-dependent individuals is inconclusive and conflicting at this time. However, further research and larger scale analysis is warranted and feasible considering the suggestive outcomes these studies represent.
