摘要
Suramin exhibited morphine-like analgesic activity in mice. It antagonized both thermal (hot-plate) and acetic acid-evoked writhing responses with ED50 values 1/100 and 1/68, respectively, that of morphine. The suramin-and morphine-induced hot-plate analgesia was suppressed by administration of 0.5 mg/kg naloxone. However, lower doses (5-30-mu-g/kg) of naloxone produced dose-related potentiation or suppression of suramin and morphine analgesia. This potentiation effect may be due to the inhibition of writhing by naloxone itself rather than be a direct antagonism of the morphine effect.
