Intrathecal administration of epinephrine inhibits and reverses analgesic tolerance to analgesic effect of morphine in rats
Introduction: Several researches have reported that stress is able to inhibit the development of morphine tolerance via activating of Hypothalamic-Pituitary-Adrenal (HPA) axis. In the present study we tried to examine the effect of epinephrine, the product of adrenal medulla, on the development of morphine tolerance. Methods: Analgesic tolerance was induced by intrathecal (i.t.) injection of...
متن کاملVoluntary and forced exercises prevent the development of tolerance to analgesic effects of morphine in rats
Objective(s):Morphine is widely used to treat chronic pain. However, its utility is hindered by the development of tolerance to its analgesic effects. Despite the renowned beneficial effects of physical exercise on cognitive functions and signs of morphine withdrawal in morphine-dependent rats, little is known about the roles of voluntary and forced exercises in tolerance to analgesic effect of...
متن کاملRepeated injections of orexin-A developed behavioral tolerance to its analgesic effects in rats
Objective(s):Reduction of pharmacological effectiveness or tolerance appears following repeated administration of many analgesic drugs. We investigated tolerance to anti-nociceptive effects of orexin-A, an endogenous potent analgesic peptide using the hot-plate test.Materials and Methods:Orexin-A was microinjected ICV (intracerebroventricular) with an interval of 12 hr for 7 continuous days and...

متن کاملPossible role for integrins in the development of tolerance to the analgesic effect of morphine in male rats
There is some evidence supporting the reduced activity of integrins following chronic administration of morphine. This reduction might play a role in morphine tolerance development. Manganese binds to the extracellular domain of integrins and makes them to be activated. The effect of integrins activation using manganese on tolerance development to the analgesic effect of morphine was investi...
