Differential effects of methadone and buprenorphine on the response of D2/D3 dopamine receptors in adolescent mice

This study suggests that exposure to various opioids carries differential probabilities of altering the highly sensitive neurochemistry of adolescent brains. Methadone exposure disturbs the D2-like receptor's response, indicating a potential risk in administering methadone to adolescents (either for the treatment of opioid dependency/abuse or for pain management). In contrast, buprenorphine appears to have a significantly lower effect on the behavioral sensitivity of D2/D3 dopamine receptors in adolescents.
