Metabolite Identification
Common NameN,N-Didemethyl orphenadrine
DescriptionN,N-Didemethyl orphenadrine is a metabolite of orphenadrine. Orphenadrine is an anticholinergic drug of the ethanolamine antihistamine class with prominent CNS and peripheral actions used to treat painful muscle spasms, other similar conditions, as well as the treatment of some aspects of Parkinson's Disease. It is closely related to diphenhydramine. Therefore, it is related to other drugs used for Parkinson's like benztropine and trihexyphenidyl, and it is also structurally related to nefopam, which is a centrally-acting yet non-opioid analgesic.
