摘要

Avanir Pharmaceuticals in the US is developing a fixed-dose combination of dextromethorphan (30mg),a weak NMDA antagonist/sigma 1 agonist,and quini-dine (30mg),a cytochrome P450-2D6 (CYP2D6) enzyme inhibitor [AVP 923,Neurodex~(?)].Quinidine sustains therapeutic levels of dextromethorphan over a 12-hour dosing schedule by inhibiting oxidative first-pass metabolism of the drug,and is used in the combination product at 2.5-5.0% of its normal daily therapeutic dose.A rolling NDA for the treatment of emotional lability has been initiated,and phase II trials with dextromethorphan/quinidine for the treatment of neuropathic pain have been completed.
