CYP2D6 phenotyping with dextromethorphan.
Genetically determined individual differences in the ability to oxidize certain drugs have raised recently a considerable interest because of clinical importance of this problem. Determination of CYP2D6 oxidation phenotype is used to obtain more efficient pharmacotherapy and to explain lower efficacy of some drugs and presentation of adverse effects in particular patients. The aim of this study...
متن کاملThe effect of acute administration of quinidine, dextromethorphan and combination of dextromethorphan/quinidine on pentylenetetrazole-induced clonic and tonic seizure thresholds in mice
Background: Dextromethorphan (DM) as a non-opioid anti-cough has neuroprotective effects. Combination of DM with quinidine decreases rapid metabolism of DM to dextrorphan (DX). This study aimed to examine the effects of acute administration of quinidine, DM and combination of dextromethorphan/quinidine (DM/Q) on pentylenetetrazole (PTZ)-induced clonic and tonic seizure thresholds in mice. Mater...
متن کاملThe dextromethorphan analog dimemorfan attenuates kainate-induced seizures via sigma1 receptor activation: comparison with the effects of dextromethorphan.
In a previous study, we demonstrated that a dextromethorphan analog, dimemorfan, has neuroprotective effects. Dextromethorphan and dimemorfan are high-affinity ligands at sigma1 receptors. Dextromethorphan has moderate affinities for phencyclidine sites, while dimemorfan has very low affinities for such sites, suggesting that these sites are not essential for the anticonvulsant actions of dimem...
متن کاملDextromethorphan to dextrorphan urinary metabolic ratio does not reflect dextromethorphan oral clearance.
Dextromethorphan urinary metabolic ratio is widely used to determine the CYP2D6 phenotype, but its utility to reflect subtle differences in catalytic activity is unclear. We evaluated the capability of dextromethorphan urinary metabolic ratio to predict dextromethorphan oral clearance as a measure of CYP2D6 activity. Data from 10 healthy extensive metabolizers of CYP2D6 were given 30 mg of dext...
متن کاملDextromethorphan and pain after total abdominal hysterectomy.
Dextromethorphan is an N-methyl-D-aspartate (NMDA) receptor antagonist which has been shown to inhibit the development of cutaneous secondary hyperalgesia after tissue trauma. We studied 60 ASA I-II patients undergoing total abdominal hysterectomy in a randomized, double-blind, placebo-controlled study. Patients received either dextromethorphan 27 mg capsules, two doses before operation and thr...
