KembaraXtra-Psychology – Barbiturate

Barbiturates are a class of drugs derived from barbituric acid that act primarily as central nervous system depressants. They exert their effects by enhancing inhibitory neurotransmission through the GABA receptor complex, producing sedation, hypnosis, and anesthesia. Once widely prescribed for anxiety and sleep disorders, their use has declined sharply due to risks of dependence, overdose, respiratory suppression, and fatal poisoning, though they retain limited medical applications.
