简要总结

This study will compare the safety and effects over time for giving both ADASUVE and lorazepam (intramuscular) compared to that of each agent given alone.

详细描述

The objective of this study is to compare the safety and pharmacodynamic profiles of concomitant administration of a single dose of ADASUVE and lorazepam (IM) compared to that of each agent administered alone. Respiratory pharmacodynamics will be monitored through recordings of respirations/minute and pulse oximetry. Other pharmacodynamic safety measures will include effects on blood pressure, heart rate, sedation and psychomotor measures of attention, information processing speed, reaction time, and coordination.

Initially, 4 subjects will receive lorazepam 1 mg IM + ADASUVE 10 mg open label to validate the dose regimen. After the safety data are reviewed and the dose regimen confirmed, 18 non-obese, healthy male or female volunteers between the ages of 18 and 50 will be enrolled in this double-blinded, double-dummy, randomized, 3-period cross-over drug interaction study.
