Barbiturates, a class of depressants, serve to slow down bodily function. The substance is synthesized from barbiturate acid, which German chemist Adolf von Baeyer (who later founded Bayer Chemical Company) discovered in 1864. The compound is derived from combining urea (found in animal urine) and malonic acid. Doctors prescribed barbiturates extensively throughout the 19th and early 20th centuries for various illnesses as “sleeping pills.” During World War 2, the military used the drug to allow soldiers in the Pacific to tolerate the extreme jungle heat. It became accessible for public use during the 1960s and 70s as a treatment for anxiety, depression, and other psychological conditions. However, the potential for abuse and addiction became known, and benzodiazepines have largely replaced their medical use. The black market continues to distribute it and, sadly, it has claimed the lives of celebrities like Elvis Presley, Marilyn Monroe, Judy Garland, and Jimi Hendrix.
Today the Food and Drug Administration classifies barbiturates as a Schedule III controlled substance, meaning they have a potential for abuse and moderate risk of physical and psychological dependence. Physicians use it rarely as a sedative, to treat seizures, epilepsy, in general anesthesia, and for assisted suicide. The government also administers it some cases of capital punishment by lethal injection.
Prescription barbiturates range in the length of their effects, from short acting to long term. Patients can choose brand names that offer the tablet, capsule, or liquid form. Many addicts also injected the substance directly into the bloodstream for more immediate effects. Here are some examples of barbiturates in the market today:
