The clinically available NMDA receptor antagonist dextromethorphan attenuates acute morphine withdrawal in the neonatal rat.

چکیده
We investigated the ability of dextromethorphan, a clinically available NMDA receptor antagonist, to attenuate the behaviors and the expression of c-fos mRNA associated with acute morphine withdrawal in the 7-day-old rat. The intensity of the acute morphine withdrawal behaviors and the elevation in c-fos mRNA expression in the brain induced by acute morphine withdrawal were reduced by dextromethorphan. Thus, dextromethorphan can attenuate acute morphine withdrawal in the developing organism.

Effect of dextromethorphan, amantadine, and ketamine on morphine withdrawal syndrome in mice
Recent studies have shown that NMDA receptors are involved in the tolerance and dependence to opioids. In addition, it has been reported that ketamine, dextromethorphan and amantadine have antagonistic activity at NMDA receptors. Therefore, this study was conducted to clarify the effect of these drugs on morphine withdrawal syndrome. Morphine dependence was induced by increasing doses of morphi...

Background and purpose : Dextromethorphan is a non-competitive NMDÂ receptor antagonist in the glutamatergic system with over 47 years of clinical usage experience as an over-the counter antitussive drug. We previously demonstrated that dextromethorphan modulates the pain threshold in the mouse acetic acid (0.6%,intraperitonealy)-induced writhing test (a tonic and chemical model for chronic p...

متن کاملThe effect of dextromethorphan on apomorphine-induced pecking behavior in chick
Dextromethorphan is an NMDA receptor antagonist in the glutamatergic system. Currently, there are some reports showing that the glutamatergic NMDA receptor mechanism stimulates dopamine release from several brain regions. This effect may in part modulate the stereotyped behaviors of dopaminergic system. The purpose of the present study was to determine the interaction between the blockade of NM...
متن کاملPharmacology of methadone and its isomers.
UNLABELLED Methadone is a synthetic opioid analgesic that is used as an alternate to morphine and hydromorphone for patients with severe pain. It is increasingly being used in opioid rotation schedules. Methadone has an asymmetric carbon atom resulting in 2 enantiomeric forms, the d and l isomers. The racemic mixture (dl-methadone) is the form commonly used clinically. Recent studies have revea...
