Lorazepam
Lorazepam is a short-acting benzodiazepine medication used to treat anxiety disorders, insomnia, seizures, and alcohol withdrawal symptoms.
Description: Lorazepam works by enhancing the activity of the neurotransmitter gamma-aminobutyric acid (GABA) in the brain, which reduces neuronal excitability and produces a calming effect. It is typically prescribed for short-term treatment of anxiety and other conditions. Compared to other benzodiazepines, lorazepam has a relatively rapid onset of action and a shorter duration of effects. Long-term use can lead to physical dependence, tolerance, and withdrawal symptoms upon discontinuation. Lorazepam also has the potential for abuse and is often misused in combination with other substances.
Lorazepam and Drug Testing: As a short-acting benzodiazepine, lorazepam can be detected in various types of drug tests for a relatively short period compared to long-acting benzodiazepines. In urine tests, lorazepam can be detected for up to 3-5 days after last use, depending on factors such as dosage, frequency of use, and individual metabolism. In hair tests, lorazepam can be detected for up to 90 days after last use. It is crucial for individuals who are prescribed lorazepam to inform employers or testing authorities to avoid false-positive results and potential consequences.
