Clinical Trials Related to Ativan (Lorazepam)

Lorazepam Sedation for Critically Ill Children [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.

ADASUVE-Lorazepam Drug-Drug Interaction [Completed]
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.

Catatonia in Nodding Syndrome and Lorazepam Treatment [Completed]
Nodding Syndrome is an enigmatic neuropsychiatric syndrome affecting children and adolescents mostly in Eastern Africa. The symptoms of Nodding Syndrome and catatonia seem to overlap. The researchers' objectives in this study were to investigate the presence and types of catatonic symptoms in children with Nodding Syndrome and observe their response to one or two doses of lorazepam, the first-line treatment for catatonia.

Intramuscular (IM) Olanzapine Versus IM Haloperidol Plus Lorazepam for Acute Agitation in Schizophrenia [Completed]
The aim of this study was to compare the efficacy and safety of intramuscular 10 mg olanzapine versus intramuscular 5 mg haloperidol plus lorazepam 2 mg in the treatment of acute agitated schizophrenic patients of Taiwanese populations.

Exploring the Effects of Diazepam and Lorazepam [Completed]
Aims :

- exploring lorazepam (0. 038 mg/kg) effects, after a single oral intake, in healthy

volunteers, on the neural correlates of encoding and retrieval of information during a word-stem completion task (implicit memory), using fMRI

- comparing lorazepam effects to diazepam (0. 3 mg/kg)effects

- exploring benzodiazepines effects, after a single oral intake, on the neural correlates

of successful encoding of information within explicit memory using fMRI Hypothesis :

- both diazepam and lorazepam will impair explicit memory performance, but lorazepam only

will impair perceptual priming

- lorazepam and diazepam will modify the normal correlates of information encoding within

explicit memory

- lorazepam only will alter the neural correlates of perceptual priming
