Study Notes
GABA and Anxiolytics
- Many anxiolytics and sedative-hypnotic agents target the GABAA receptor.
- The main inhibitory neurotransmitter in the brain is GABA (Gamma-Aminobutyric Acid).
- The class of drugs that includes Alprazolam and Diazepam is Benzodiazepines.
- Anxiolytics have an agonist effect on the GABAA receptor, increasing the frequency of chloride channel opening, which leads to a decrease in neuronal activity.
- The main difference between sedatives and hypnotics is their effect on the level of consciousness: sedatives reduce anxiety and agitation, while hypnotics induce sleep.
