Summary
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.
Clinical Details
Official title: ADASUVE®-Lorazepam Drug-Drug Interaction Study
Study design: Allocation: Randomized, Endpoint Classification: Safety Study, Intervention Model: Crossover Assignment, Masking: Double Blind (Subject, Caregiver, Investigator, Outcomes Assessor)
Primary outcome: Pharmacodynamic effects on respiration
Secondary outcome: Pharmacodynamic effects on vital signsPharmacodynamic effects on sedation Pharmacodynamic effects on psychomotor measures
Detailed description:
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.
Eligibility
Minimum age: 18 Years.
Maximum age: 50 Years.
Gender(s): Both.

- Subjects who are in good general health prior to study participation as determined by
a detailed medical history, physical examination, 12-lead ECG, blood chemistry
profile, hematology, urinalysis, and in the opinion of the Principal Investigator.

use a medically acceptable and effective birth control method throughout the study
and for 30 days following the end of the study
- Male participants (if sexually active with a partner of child-bearing potential) who

chronic obstructive lung disease, or any use of an inhaler prescribed for wheezing or
bronchospasm must be excluded; sleep apnea; acute narrow-angle glaucoma; any

short term situational anxiety or depression of < 2 years duration; any substance
abuse or addiction within the last 2 years; pregnancy within the past 6 months.
- Subjects who have taken prescription or nonprescription medication within 7 days of
Visit 2.
- Subjects who have had an acute illness within the last 7 days of Visit 2.

- Subjects who have any other disease(s), by history, physical examination, or
laboratory abnormalities that, in the investigator's opinion, presents undue risk to
the subject or may confound the interpretation of study results.

candidate for receiving lorazepam or ADASUVE.
