Barbiturates

Excerpt

Barbiturates are a category of sedative-hypnotic medications used for treating seizure disorders, neonatal withdrawal, insomnia, preoperative anxiety, and the induction of coma to address increased intracranial pressure (ICP). In addition, these medications are also helpful for inducing anesthesia. Thiopental, introduced in 1934 for general anesthesia induction, served as the primary intravenous anesthetic induction agent until propofol replaced it. Barbiturates approved by the US Food and Drug Administration (FDA) for clinical use include phenobarbital, methohexital, butalbital, pentobarbital, primidone, and amobarbital.
