Dopamine agonists like amantadine, bromocriptine, and pergolide are not effective for treating cocaine dependence. Further research is needed to find treatments that help patients remain in therapy.
Area of Science:
- Neuroscience
- Pharmacology
- Psychiatry
Background:
- Cocaine dependence is a significant public health issue with severe medical, psychological, and social consequences.
- Withdrawal symptoms include craving, depression, fatigue, irritability, anorexia, and sleep disturbances.
- Cocaine use alters dopamine levels, suggesting dopamine-targeting drugs might be beneficial.
Purpose of the Study:
- To assess the efficacy and acceptability of dopamine agonists for treating cocaine dependence.
Main Methods:
- Systematic review of randomized controlled trials identified through extensive electronic database searches and other sources.
- Included trials focused on dopamine agonists for cocaine dependence treatment.
- Data extraction and analysis included Relative Risks and number needed to treat, with sensitivity analyses for dropouts.
Main Results:
- Seventeen studies with 1224 participants evaluated amantadine, bromocriptine, and pergolide.
- No significant differences were found between dopamine agonists and controls for cocaine metabolite levels or treatment retention.
- Efficacy and acceptability outcomes were similar across different participant groups.
Conclusions:
- Current evidence does not support the use of dopamine agonists for treating cocaine dependence.
- Alternative or additional supportive measures are recommended to improve patient retention in treatment.

Adrenergic Agonists: Indirect-Acting Agents
One mechanism involves depleting stored catecholamines by displacing them from synaptic vesicles. These agents, known as "displacers," are transported into vesicles at the expense of noradrenaline. Examples include amphetamine and tyramine, which lack a catechol moiety, resulting in prolonged action, improved oral bioavailability, and...
