| Hazard Classes and Categories | Repr. 2 (93.1%) |
| Treatment | General supportive and symptomatic measures are recommended. Vital signs must be monitored and the patient closely observed. When there is a risk of aspiration, induction of emesis is not recommended. Gastric lavage may be indicated if performed soon after ingestion or in symptomatic patients. Administration of activated charcoal may also limit drug absorption. (L1712) |
| 건강 영향 | They cause slurred speech, disorientation and "drunken" behavior. They are physically and psychologically addictive. May cause a potentially dangerous rash that may develop into Stevens Johnson syndrome, an extremely rare but potentially fatal skin disease. |
| Hepatotoxicity | Lorazepam, as with other benzodiazepines, is rarely associated with serum ALT or alkaline phosphatase elevations during therapy, and considering its widescale use, clinically apparent liver injury from lorazepam is extremely rare. There has been only a single case report of symptomatic, acute liver injury from lorazepam. The latency to onset was 9 months and the clinical pattern that of a self-limited cholestatic hepatitis that resolved within 2 months of stopping. Similar isolated single cases of clinically apparent hepatitis have been reported with other benzodiazepines including alprazolam, chlordiazepoxide, clonazepam, diazepam, flurazepam and triazolam. The clinical pattern of acute liver injury from benzodiazepines is typically cholestatic and mild-to-moderate in severity with a latency of 1 to 6 months. Fever and rash are not common nor is autoantibody formation. |
| 유해 작용 | Similar to most benzodiazepines, lorazepam can induce adverse reactions such as CNS and respiratory depression, which are dose-dependent. Additional adverse effects of the drug are observed with higher doses. |

일반 설명
Lorazepam, 7-chloro-5-(2-chlorophenyl)-3-dihydro-3-hydroxy-2H-1,4-benzodiazepine-2-one(Ativan), is the 2'-chloro derivative of oxazepam. In keepingwith overall SARs, the 2'-chloro substituent increases activity.As with oxazepam, metabolism is relatively rapid anduncomplicated because of the 3-hydroxyl group in the compound.Thus, it also has short half-life (2–6 hours) and similarpharmacological activity.
