Ativan is a type of benzodiazepine, and all medications in this drug group can have these effects to some degree, depending on the specific benzodiazepine that is being taken. These medications work in the brain by enhancing the effects of gamma-aminobutyric acid (GABA), a chemical that is naturally calming. GABA can slow down or stop certain nerve signals in the brain. This is why Ativan and other benzodiazepines are known as mild tranquilizers, sedatives, or central nervous system depressants (CNS depressants).
