What are barbiturates?

Barbiturates are central nervous depressants. They reduce the activity of nerves causing muscle relaxation. They can reduce heart rate, breathing, and blood pressure. All barbiturates affect gamma-aminobutyric acid (GABA), a neurotransmitter (chemical) that nerves use to communicate with one another.

For what conditions are barbiturates prescribed?
