Does Ativan affect dopamine?

What neurotransmitter does lorazepam work on?

Gamma-aminobutyric acid (GABA) is a neurotransmitter, a chemical that nerves in the brain use to send messages to one another that reduces the activity of nerves in the brain. It is thought that lorazepam and other benzodiazepines may act by enhancing the effects of GABA in the brain to reduce activity.

What effect does Ativan have on the brain?

By calming this excessive activity, Ativan helps to relieve symptoms of anxiety, such as restlessness, tension, irrational fears, and irritability.

What does lorazepam do to your brain?

How long will Ativan stay in your system?

Can Ativan cause a stroke?

Benzodiazepines were associated with a similar risk of stroke as benzodiazepine-like drugs. The use of benzodiazepines and benzodiazepine-like drugs was associated with an increased risk of any stroke and ischemic stroke, whereas the association with hemorrhagic stroke was not significant.
