Ativan (Lorazepam) - Summary



ATIVAN (lorazepam) Injection
Rx only

Lorazepam, a benzodiazepine with antianxiety, sedative, and anticonvulsant effects, is intended for the intramuscular or intravenous routes of administration. It has the chemical formula: 7-chloro-5(2-chlorophenyl)-1,3-dihydro-3-hydroxy-2 H -1, 4-benzodiazepin-2-one.

Status Epilepticus

ATIVAN Injection is indicated for the treatment of status epilepticus.


ATIVAN Injection is indicated in adult patients for preanesthetic medication, producing sedation (sleepiness or drowsiness), relief of anxiety, and a decreased ability to recall events related to the day of surgery. It is most useful in those patients who are anxious about their surgical procedure and who would prefer to have diminished recall of the events of the day of surgery (see PRECAUTIONS, Information for Patients).

Clinical Trials Related to Ativan (Lorazepam)

Fasting Study of Lorazepam Tablets 2 mg and Ativan Tablets 2 mg [Completed]
The objective of this study was to investigate the bioequivalence of Mylan's lorazepam 2 mg tablets to Wyeth's Ativan 2 mg tablets following a single, oral 2 mg (1 x 2 mg) dose administered under fasting conditions.

Efficacy and Safety Study Comparing Lorazepam and Diazepam for Children in the Emergency Department With Seizures (Status 2) [Recruiting]
Children with seizures are frequently seen in the emergency department. The drug lorazepam, which is commonly used, is not labeled by the US Food and Drug Administration for children for this use. The FDA, under the Best Pharmaceuticals for Children Act, has requested that a study comparing diazepam, a drug that is labeled by the FDA for this indication, with lorazepam be performed. The study will show whether one drug is more effective and safe than the other.

Lorazepam Sedation for Critically Ill Children [Suspended]
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.

Lorazepam, Diphenhydramine Hydrochloride, and Haloperidol Gel in Patients With Nausea [Recruiting]
This randomized clinical trial studies lorazepam, diphenhydramine hydrochloride, and haloperidol gel in patients with nausea. Lorazepam, diphenhydramine hydrochloride, and haloperidol gel, when absorbed into the skin, may be an effective treatment for nausea and vomiting.

Effect of Additive Lorazepam on Patient Satisfaction as a Premedication in Diagnostic Flexible Bronchoscopy [Recruiting]
Many patients undergoing flexible bronchoscopy (FB) experience anxiety and discomfort during the procedure. The investigators want to evaluate whether an additional Lorazepam premedication would improve patient satisfaction for FB.
