“these data suggest that R-MDMA could be a more viable therapeutic option for the treatment of PTSD and other disorders for which S/R-MDMA is currently being investigated” since “R-MDMA unlike racemic MDMA, did not increase locomotor activity, produce signs of neurotoxicity, or increase body temperature.
A key pharmacological difference between R-MDMA and racemic MDMA is that R-MDMA has much lower potency as a dopamine releaser. Together, these results indicate that the prosocial and therapeutic effects of S/R-MDMA may be SEPARABLE from the stimulant, thermogenic, and potential neurotoxic effects.”
