Condition(s) targeted: Critical Illness

Intervention: Lorazepam (Drug); Midazolam (Drug); Lorazepam CI (Drug)

Phase: Phase 2/Phase 3

Status: Completed

This clinical trial is being performed under the Best Pharmaceuticals for Children Act, signed into law in 2002 in order to improve pediatric labeling for off-patent drugs. The purpose of this study is to make sure that lorazepam, when given to children who are very sick in the Intensive Care Unit and who are on a breathing machine, is safe and works as well as a drug called midazolam. Midazolam is already approved by the FDA for this use, but lorazepam is not, even though both drugs are commonly used for sedation.

Clinical Details

Official title: A Randomized Controlled Trial Comparing Lorazepam With Midazolam for Sedation of Mechanically Ventilated Pediatric Patients

Study design: Allocation: Randomized, Endpoint Classification: Safety/Efficacy Study, Intervention Model: Parallel Assignment, Masking: Single Blind (Outcomes Assessor), Primary Purpose: Treatment

Primary outcome:

Rate of Severe Adverse Events

Number of bolus doses required to achieve a comfort score of 17 ≤ 26

Drug dose required to maintain a target comfort score of 17 ≤ 26

Detailed description: Lorazepam is used clinically for sedation of mechanically ventilated children, but has not been approved by the FDA for this indication in children. The purpose of this study, in response to the Written Request by FDA, is to determine the safety, efficacy, and dosage required for lorazepam compared with midazolam, which is approved by FDA for children for this indication. Study participants must be children who are critically ill and receiving mechanical ventilation who require sedation. Participants will be randomized to lorazepam (intermittent bolus or continuous infusion) or midazolam (continuous infusion). Sedation will be monitored using the COMFORT score. Blood will be drawn to measure lorazepam/midazolam plasma concentrations, and to measure the plasma concentrations of excipients (benzyl alcohol and glycols) in patients receiving lorazepam.


Minimum age: N/A. Maximum age: 18 Years. Gender(s): Both.


Inclusion Criteria:

to 24 hr

- Patients in whom the use of neuromuscular blocking agents would normally NOT be

expected to be used.

- Patients with cardiac, renal, or hepatic dysfunction will be actively sought

Exclusion Criteria:

- Life expectancy < 48 hr

- Expected duration of sedation < 48 hr

- Patient with history of hypersensitivity to any component of lorazepam, midazolam,

fentanyl, thiopental

- Females pregnant or breast feeding

- Patient requires sedatives or analgesics other than study drug
