• Description: Barbituric acid, the precursor of barbiturates, was first produced in 1864 by condensation of malonic acid and urea; it had no central nervous system (CNS) effects. In 1903, diethyl barbituric acid (barbital) was created as the first barbiturate with CNS inhibitory effects. Barbiturates were commonly used as sedative-hypnotics in the mid-twentieth century; meantime they were abused by some people as sold on the street. Use of barbiturates quickly dropped after introduction of benzodiazepines as the safer sedative-hypnotics. However some of the barbiturates are still used as anticonvulsants and some for euthanasia.
• Uses: Sedative, hypnoyic. Controlled substance (depressant). Human Pentobarbital as sodium salt has been used as a sedative and hypnotic in the short-term management of insomnia. Pentobarbital sodium has also been used for premedication in anesthetic procedures. Pentobarbital is FDA-approved for the emergency control of certain acute convulsive episodes, e.g., those associated with status epilepticus, cholera, eclampsia, meningitis, tetanus, and toxic reactions to strychnine or local anesthetics. The other indications for pentobarbital include treatment of nonfatal submersion and traumatic/nontraumatic raised intracranial pressure. Animal Intraperitoneal (IP) injection of pentobarbital is used in experimental medicine as an anesthetic in small animals such as rat and mouse. Pentobarbital is an important drug for relieving convulsive seizures, especially when caused by strychnine.
• Therapeutic Function: Hypnotic, Sedative
