Which medication is classified as a sedative?

Ativan, known generically as lorazepam, is classified as a sedative and belongs to the benzodiazepine class of medications. It is commonly used to treat anxiety, insomnia, and seizure disorders, and it works by enhancing the effects of a neurotransmitter called gamma-aminobutyric acid (GABA) in the brain, which results in a calming effect. This mechanism makes Ativan effective for sedation in various clinical situations, such as preoperative anxiety management or for acute agitation.

The other medications listed serve different purposes: Flexeril (cyclobenzaprine) is a muscle relaxant, Mobic (meloxicam) is a nonsteroidal anti-inflammatory drug (NSAID) used to relieve pain and inflammation, and Ritalin (methylphenidate) is a stimulant primarily used in the treatment of Attention Deficit Hyperactivity Disorder (ADHD). Their actions do not induce sedation, which further reinforces that Ativan is the correct answer regarding the classification as a sedative.
