How does lorazepam work? from buyxanaxpillsnow's blog

The sedative-hypnotic medication lorazepam is used to reduce stress and anxiety. It may be ingested or administered intravenously. In order to clarify how it functions, lorazepam, a benzodiazepine, binds to receptors in the brain and spine. One receptor among several is known as GABA. 

GABA is in charge of producing a "feel good" sensation by regulating abnormal nerve cell activity. This can result in sleepiness, vertigo, and impaired vision because lorazepam binds to GABA and prevents nerve cells from talking to one another, which calms the brain and causes the CNS to be depressed.
