Lorazepam is the generic name for the brand-name drug Ativan [1][2].
What is Ativan used for?
Ativan, with its generic name lorazepam, is a prescription medication belonging to the benzodiazepine class. It is primarily used to treat anxiety disorders and insomnia [1][3]. It can also be used to manage seizures and as a sedative before medical procedures [1].
How does lorazepam work?
Lorazepam functions by enhancing the effects of a neurotransmitter called gamma-aminobutyric acid (GABA) in the brain. GABA is an inhibitory neurotransmitter, meaning it reduces nerve activity. By increasing GABA's effects, lorazepam helps to calm the brain, leading to its therapeutic effects in anxiety and sleep disorders [1].
When did Ativan become available?
The brand-name drug Ativan was first approved by the U.S. Food and Drug Administration (FDA) in 1977 [4].
What are other brand names for lorazepam?
While Ativan is the most common brand name for lorazepam in the United States, it may be marketed under other names internationally [2].
Can you get lorazepam without a prescription?
No, lorazepam is a controlled substance and requires a prescription from a qualified healthcare provider due to its potential for dependence and abuse [1].
What are the side effects of lorazepam?
Common side effects of lorazepam can include drowsiness, dizziness, fatigue, and unsteadiness [1]. More serious side effects can occur, and patients should discuss potential risks with their doctor [1].
How long does lorazepam stay in your system?
The half-life of lorazepam, the time it takes for the amount of drug in the body to be reduced by half, is typically around 10 to 20 hours [5]. This means it can take several days for the drug to be fully eliminated from the body.
Are there alternatives to lorazepam?
Yes, there are other medications available for anxiety and insomnia, including other benzodiazepines, antidepressants, and certain non-benzodiazepine sleep aids. The choice of alternative depends on the specific condition being treated and individual patient factors [1].
What is the difference between lorazepam and other benzodiazepines?
While all benzodiazepines work by enhancing GABA, they differ in their potency, onset of action, and duration of effect. Lorazepam is considered an intermediate-acting benzodiazepine [1]. Other common benzodiazepines include diazepam (Valium) and alprazolam (Xanax), which have different pharmacokinetic profiles [6].
