In light of a recent demonstration that probenecid enhanced the central nervous system (CNS) uptake of morphine-3-glucuronide (M3G), we investigated the consequences of probenecid co-administration for the spinal cord concentrations and antinociceptive effects of morphine-6-glucuronide (M6G) in rats...
