Barbiturates have about 2500 derivatives of barbituric acid and are known by a variety of names. Which of the following is another name for a barbiturate?

Butisol is indeed another name for a barbiturate, specifically a barbiturate designed for use as a sedative and anxiolytic medication. It is derived from barbituric acid and belongs to the class of medications that can depress the central nervous system. This classification allows it to be effective in inducing sleep, relieving anxiety, and acting as a muscle relaxant.

Barbiturates are a large group of drugs that were widely used for their sedative properties, although their use has declined due to the risk of dependence and overdose. The extensive variety of names and derivatives illustrates the historical prevalence and therapeutic utility of barbiturates in the medical field.

The other names mentioned in the choices refer to different classes of medications. Demerol (meperidine) is an opioid analgesic, Pethadol is a synthetic opioid, and Leritine is not recognized as a barbiturate but rather falls outside the scope of sedative-hypnotic drugs. This distinction reinforces why Butisol is correctly identified as a barbiturate.
