Opioids increase the dopaminergic turnover in nucleus striatum and nucleus accumbens of mice, causing behavioural changes such as increased locomotion and food intake. We have now shown that L-arginine administration increases morphine-induced locomotion and changes in food intake in mice. D-Arginine had no effect, suggesting a stereospecific mechanism. Furthermore NG-nitro-L-arginine methyl ester, a specific inhibitor of nitric oxide synthase, reduced the morphine-induced effects. These results suggest that endogenous nitric oxide could play a role in the modulation of dopaminergic effects elicited by morphine.
