Barbiturates are a class of medications that act as central nervous system depressants. They are primarily used to treat anxiety, insomnia, and seizure disorders. Barbiturates work by enhancing the effects of a neurotransmitter called GABA, which helps to calm brain activity.
These drugs can be effective in certain medical situations, but they also carry a risk of dependence and overdose. Due to their potential for abuse, many barbiturates have been replaced by safer alternatives, such as benzodiazepines, in clinical practice. Proper medical supervision is essential when using these medications.
