Subunit-dependent inhibition and potentiation of 5-HT3 receptor by the anticancer drug, topotecan.

abstract：:Morphine is a key drug for the treatment of pain but its side effects limit its clinical application. MEL-0614, an endomorphin-1 analog, has fewer side effects than morphine in addition to its powerful analgesic effect. In this study, we measured the effect of morphine and MEL-0614 on hyperalgesia (7 days) and neuropa...
