Condition or disease | Intervention/treatment | Phase |
---|---|---|
Healthy | Drug: i.v. fentanyl and AeroLEF | Phase 1 |
In Period I, subjects received an intravenous dose of fentanyl (200 µg) administered over 1 minute (Treatment A). Subjects then crossed over to Period II.
In Period II, subjects were randomly assigned to receive either 2 mL (1000 µg fentanyl; Treatment B) or 3mL (1500 µg fentanyl; Treatment C) of AeroLEF delivered by nebulization with the AeroEclipse BAN. Subjects were instructed to continue inhalation of AeroLEF for approximately 1 minute beyond the point of nebulizer sputter to ensure that all aerosolized medication was delivered. There was at least a 1 week washout period between study periods.
