What is an example of a barbiturate?

Phenobarbital is indeed an example of a barbiturate. Barbiturates are a class of drugs that act as central nervous system depressants, and they were historically used for their sedative and anxiolytic properties. Phenobarbital, in particular, is used primarily to manage seizures and as a sedative, showcasing the therapeutic applications of this category of drugs.

Understanding the classification of drugs is crucial, as it helps differentiate between various substances based on their chemical structure and effects on the body.

Recognizing these distinctions aids in comprehending both medical uses and the potential for misuse associated with different drug classes.
