Pharmacokinetics & Tolerability Study of MAP0004 in Smoking and Non-Smoking Adult Volunteers

An Open-Label, 2-Period, Crossover Phase 2 Study Comparing the Pharmacokinetics and Tolerability of Dihydroergotamine Mesylate (DHE) Delivered Intravenously (DHE 45) and by Oral Inhalation (MAP0004) in Smoking and Non-Smoking Adult Volunteers

Compare the pharmacokinetics of Dihydroergotamine Mesylate (DHE) delivered by oral inhalation (MAP0004) or Intravenous (IV) DHE in smokers versus non-smokers.
