- Classifications (Not All Inclusive):
- Volatile Liquids: Liquids that evaporate readily at room temperature, such as ether, halothane, isoflurane, sevoflurane, and desflurane.
- Gases: Include nitrous oxide.
- Route of Administration: Inhaled through the lungs.
- Mechanism of Action: Inhaled anesthetics enhance the activity of the inhibitory neurotransmitter GABA (gamma-aminobutyric acid) in the brain, resulting in a sedative and anesthetic effect.
