Metabolite Identification
Common NameEletriptan N-oxide
DescriptionEletriptan N-oxide is a metabolite of eletriptan. Eletriptan (also known as eletriptan hydrobromide) is a second generation triptan drug intended for treatment of migraine headaches. It is used as an abortive medication, blocking a migraine attack which is already in progress. Eletriptan is marketed and manufactured by Pfizer Inc.
