• Status: Completed
• Trial end date: 1969-12-31
• Target enrollment: 0
• Participant gender: All

Summary

The study objective is to determine the effect of the ethanolic solutions inhaled from the Metered dose inhaler (MDI) (15.5 mg, 31.2 mg and 62.4 mg of ethanol) and from Respimat® (18.4 of ethanol) on the breath alcohol measurements in healthy volunteers.

Secondary aim is to determine the linear dose-effect for the HFA 134a-MDI doses. An open, randomized, four-way-cross-over design is chosen. The randomization is balanced and stratified in accordance with predicted values of the volunteers of Total Lung Capacity (TLC)
