Clinical example: Diazepam has long been a drug of choice for status epilepticus; its high lipid solubility means it gets absorbed with equal speed whether given orally, or rectally (nonintravenous routes are convenient in outside hospital settings), but diazepam's high lipid solubility also means it does not remain in the.
Giving 2 mg oral lorazepam will result in a peak total serum level of around 20 ng/ml around two hours later, half of which is lorazepam, half its inactive metabolite, lorazepam-glucuronide. Lorazepam serum levels are proportional to the dose administered. This metabolism does not involve hepatic oxidation, so is relatively unaffected by reduced liver function. Lorazepam-glucuronide is more water-soluble than its precursor, so gets more widely distributed in the body, leading to a longer half-life than lorazepam.

When treatment is started. Pregnancy: Benzodiazepines should not be used during pregnancy, especially during the first and last trimesters.
Although hypotension has occurred only rarely, benzodiazepines should be administered with caution to patients in whom a drop in blood pressure might lead to cardiovascular or cerebrovascular complications. Such reactions may be more likely to occur in children and the elderly. Periodic haematologic and liver-function assessments are recommended where repeated courses of treatment are considered clinically necessary. (See section 4.6) 4.3 Contraindications • Hypersensitivity to benzodiazepines or to any of the other ingredients • Acute pulmonary insufficiency: respiratory depression; sleep apnoea (risk of further respiratory depression) • Obsessional states (inadequate evidence of safety and efficacy) • Severe hepatic insufficiency (may precipitate encephalopathy) • Planning a pregnancy (see section 4.6) • Pregnancy (unless there are compelling reasons- see section 4.6) • Myasthenia gravis; Benzodiazepines should not be used alone in depression or anxiety with depression (may precipitate suicide) 4.4 Special warnings and precautions for use Patients should be advised that since their tolerance for alcohol and other CNS depressants will be diminished in the presence of Lorazepam, these substances should either be avoided or taken in reduced dosage.
Anxiety or tension associated with the stress of everyday life usually does not require treatment with an anxiolytic.

(See DRUG INTERACTIONS ). Use of benzodiazepines, including lorazepam, both used alone and in combination with other CNS depressants, may lead to potentially fatal respiratory depression.
Anxiety or tension associated with the stress of everyday life usually does not require treatment with an anxiolytic.
However, in some cases, some short-term symptoms may not improve and intensify over time to become long-term symptoms—becoming part of a post-acute withdrawal syndrome. Some of these longer-term withdrawal symptoms may continue for several months after last use. These signs and symptoms may include:.

Considering that, it will take about 3.6 days to compley excrete it from the system.Ativan is metabolized to a compound called lorazepam glucuronide. This metabolite may take much longer to exit the body than the actual drug itself. Lorazepam glucuronide can last in the body for up to 5 days and can be detected in the.
Metabolite lorazepam glucuronide tends to stay in the system for much longer so it may be detected for up to 9 days in the urine. A urine test can be used to detect lorazepam in urine for up to 6 days. Urine tests are a preferable choice since they are non-invasive and easier to perform. The period may extend to a week in case of long term users.
Lorazepam is a benzodiazepine prescribed by the doctors to treat anxiety and panic attacks. It may take quite some time for the drug to be compley detoxified.
