PRIMARY STUDY

The endocannabinoid system and psychiatric disorders.

Key Findings:  There is a potential for pharmacological manipulation of the endocannabinoid system as a novel approach for treating schizophrenia, although experimental findings are still controversial, often with different effects depending on the drug, the dose, the species and the model used for simulating positive or negative symptoms. Besides all these limitations, SR141716A and cannabidiol show the most constant antipsychotic properties in dopamine- and glutamate-based models of schizophrenia, with profiles similar to an atypical antipsychotic drug.
