Participant Flow

Recruitment was conducted at the University of Iowa by advertisements in the "Noon News", a UIHC newsletter, and by a mass email that was sent to all staff/faculty/and students. Recruitment began in November 2016 and continued until the enrollment goal of 24 participants completing all arms of the study was reached in March 2017.

Measure
Transderm Scop®, Then IV Scopolamine Hydrbromide
Participants wore a Transderm Scop® patch (1.5 mg) for 3 days and received a single intravenous dose of 0.4 mg scopolamine hydrobromide in a crossover design with adequate washout in between.
IV Scopolamine HBr, Then Transderm Scop®
Participants received a single intravenous dose of 0.4 mg scopolamine hydrobromide and will wore a Transderm Scop® patch (1.5 mg) for 3 days in a crossover design with adequate washout in between.

PRIMARY outcome

Timeframe: Measured at time points: pre-dose, 1,2,3,4,5,6,8,10,12,24,36,48,60, and 72 hours during Intervention: Transderm Scop® and at time points: pre-dose, 2.5,5,10,20,30,45 minutes, 1.5,2,3,4,5,6,8,10,12 hours during Intervention: scopolamine HBr

Population: The number of participants analyzed represents the total number of participants that completed both interventions.
