Tolerance to the anticonvulsant effects tends to correlate more with alcohol-related deaths what to know tolerance to physiological effects, however, meaning that they are still a viable option for long-term epilepsy treatment. Patients with comorbid conditions are at higher risk for toxicity than patients without. They are derivates of barbituric acid and were introduced clinically in the early 1900s.
Why do doctors prescribe barbiturates?
A class of drugs known as benzodiazepines has largely replaced barbiturates for both medical and recreational use, although benzodiazepines also carry a high risk of physical dependence and other adverse effects. The prolonged use of barbiturates—especially secobarbital and pentobarbital—may cause the development of a tolerance to them and require amounts much larger than the original therapeutic dose. Denial of a barbiturate to the habitual user may precipitate a withdrawal syndrome that is indicative of physiological dependence on the drug. An overdose of barbiturates can result in coma and even death due to severe depression of the central nervous and respiratory systems. When barbiturates are used in anesthesia, supervision by anesthetics and certified registered nurse anesthetists is necessary.

Between the 1940s and ’70s, however, the abuse of barbiturate drugs became highly prevalent in Western societies. In North America barbiturates were widely used by youth gangs and deviant subcultures as depressants and attracted notoriety because they were often taken in combination with other substances (e.g., stimulants such as amphetamines). Alcohol greatly intensifies the depressant effect of barbiturates, and in the 1950s and ’60s, barbiturates taken with alcohol became a common agent in suicide cases.
Psychiatric disorders such as functional coma and catatonia may also be considered. A point-of-care glucose level should be determined for any patient with altered mental status to assess for hypoglycemia. A complete blood count and comprehensive metabolic panel should be obtained to further evaluate for hepatic disease, renal insufficiency, or other metabolic derangements. A pregnancy test should be conducted for any woman of childbearing age. A serum lactic acid level can help assess for cellular hypoperfusion.
Because of its relaxing effects on many of the body’s organs, long-term barbiturate use can lead to breathing problems and pneumonia.
