Previous findings have shown that sigma-1 receptors are upregulated by the self-administration of methamphetamine, whereas sigma-1 receptor antisense can attenuate the behavioral effects of psychostimulants in rodents. We examined the effects of the selective sigma-1 receptor agonist SA4503 on the rewarding effects of abused drugs. SA4503 significantly attenuated the abused drug-induced place preference. These results suggest that SA4503 inhibits the rewarding effects of abused drugs.
