Microdialysis was used to sample morphine 6-glucuronide (M6G) and morphine in striatal extracellular fluid after systemic administration in awake, freely moving rats. Morphine or M6G (25-67 mumol/kg) was given subcutaneously, and blood and striatal dialysate were sampled repeatedly during 120 min. Blood samples were obtained by indwelling catheters in the(More)
Morphine-6beta-glucuronide is a major metabolite of morphine with potent analgesic actions. To explore the importance of this opiate when administered as a drug by its own or in morphine action, we studied the locomotor activity response to morphine and morphine-6-glucuronide in drug-naive C57 BL/6JBom mice. The effects of administration of the two opiates(More)
