Reversal of morphine analgesic tolerance by ethanol in the mouse.
The chronic use of opioids in humans, accompanied by the development of tolerance, is a dangerous phenomenon in its own right. However, chronic opioid use is often made more dangerous by the coconsumption of other substances. It has been observed that the blood level of opioids in postmortem analyses of addicts, who consumed ethanol along with the opioid, was much less than that observed in ind...

متن کاملMechanisms underlying morphine analgesic tolerance and dependence.
The mechanisms underlying opioid tolerance are not fully understood, but appear to be comprised of two types of plasticity or counter-adaptation, at the cellular level and through neuronal circuits. Current studies mostly emphasize the cellular adaptation mechanisms, which include altered gene expression and receptor desensitization due to phosphorylation and endocytosis. However, the mechanism...
متن کاملIntrathecal 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 کاملReversal of behavioral effects of pentylenetetrazol by the neuroactive steroid ganaxolone.
Neuroactive steroids are naturally occurring or synthetically derived compounds many of which have anticonvulsant, anesthetic, anxiolytic, analgesic or hypnotic properties. The major site of neuronal activity appears to be with a specific steroid-sensitive site on the gamma-aminobutyric acidA receptor/chloride ionophore complex. Ganaxolone (3 alpha-hydroxy-3 beta-methyl-5 alpha-pregnan-20-one) ...
