Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The design will be a randomized, double-blind, comparative, placebo- and active-controlled nine-period crossover study in healthy male volunteers. Subjects will be randomized and will receive each of the 9 treatments which will be separated by a minimum of 48 hours.The first treatment arm will always be the intravenous remimazolam. Eligible subjects will then be randomized to treatment sequence prior to study drug administration in treatment period 2. Each subject will participate in the study for up to 51 days, from Screening until Follow-up.

8. Previous experience with intranasal drug application (within the last year)
9. Ability and willingness to abstain from alcohol, caffeine, and xanthine containing beverages or food (e.g., coffee, tea, cola, chocolate, energy drinks) from 24 hours (1 day) prior to admission to the clinical facility on Day 0 until study discharge.
