Which of the following is a type of benzodiazepine?

Lorazepam is a type of benzodiazepine, which is a class of medications commonly used to treat anxiety, insomnia, seizures, and muscle spasms. Benzodiazepines work by enhancing the effects of a neurotransmitter called gamma-aminobutyric acid (GABA) in the brain, leading to a calming effect on the nervous system. This makes lorazepam effective for immediate relief in acute anxiety situations.

In contrast, other medications listed serve different purposes. Sertraline and fluoxetine are selective serotonin reuptake inhibitors (SSRIs), primarily used as antidepressants. Quetiapine is an atypical antipsychotic used for conditions like schizophrenia and bipolar disorder. Unlike benzodiazepines, these medications operate through different mechanisms and are not primarily utilized for the same immediate anxiolytic effects that lorazepam provides.
