How long does it take for lorazepam to absorb?
Following intramuscular administration, lorazepam is completely and rapidly absorbed reaching peak concentrations within 3 hours. A 4-mg dose provides a Cmax of approximately 48 ng/mL. Following administration of 1.5 to 5.0 mg of lorazepam IM, the amount of lorazepam delivered to the circulation is proportional to the dose administered.
How much Lorazepam should I give?
For the primary purpose of sedation and relief of anxiety, the usual recommended initial dose of lorazepam for intravenous injection is 2 mg total , or 0.02 mg/lb (0.044 mg/kg), whichever is smaller. This dose will suffice for sedating most adult patients and ordinarily should not be exceeded in patients over 50 years of age. In those patients in whom a greater likelihood of lack of recall for perioperative events would be beneficial, larger doses as high as 0.05 mg/kg up to a total of 4 mg may be administered (see
What is the most important risk associated with the use of Ativan Injection in Status Epilepticus?
The most important risk associated with the use of ATIVAN Injection in status epilepticus is respiratory depression. Accordingly, airway patency must be assured and respiration monitored closely. Ventilatory support should be given as required.
How much Ativan should I give for epilepsy?
For the treatment of status epilepticus, the usual recommended dose of ATIVAN Injection is 4 mg given slowly (2 mg/min) for patients 18 years and older. If seizures cease, no additional ATIVAN Injection is required. If seizures continue or recur after a 10- to 15-minute observation period, an additional 4 mg intravenous dose may be slowly administered. Experience with further doses of ATIVAN is very limited. The usual precautions in treating status epilepticus should be employed. An intravenous infusion should be started, vital signs should be monitored, an unobstructed airway should be maintained, and artificial ventilation equipment should be available.
What is ativan injection?
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.

More than half the patients in each study had tonic-clonic status epilepticus; patients with simple partial and complex partial status epilepticus comprised the rest of the population studied, along with a smaller number of patients who had absence status.
What is the mechanism of action of lorazepam?
Lorazepam interacts with the γ-ami nobutyric acid (GABA) -benzodiazepine receptor complex, which is widespread in the brain of humans as well as other species. This interaction is presumed to be responsible for lorazepam ’s mechanism of action. Lorazepam exhibits relatively high and specific affinity for its recognition site but does not displace GABA. Attachment to the specific binding site enhances the affinity of GABA for its receptor site on the same receptor complex. The pharmacodynamic consequences of benzodiazepine agonist actions include antianxiety effects, sedation, and reduction of seizure activity. The intensity of action is directly related to the degree of benzodiazepine receptor occupancy.
How long does lorazepam stay in your system?
