alcohol and cocaine dependence is underway (Identifier: NCT00167245 and NCT00223626). The anticonvulsant and mood stabilizer drug lamotrigine also exhibits antagonistic effects on AMPAR and reduces glutamate release (Lee et al., 2008). Importantly, two open-label studies have correlated lamotrigine with significant reductions in cocaine craving and use (Brown et al., 2003). Additional studies are recruiting patients at the time that this review was prepared (Identifier: NCT00280293).
