Efficacy and tolerability of benzodiazepines versus antidepressants in anxiety disorders: a systematic review and meta-analysis. The first benzodiazepine, chlordiazepoxide (Librium), was discovered accidentally by Leo Sternbach in 1955 and was made available in 1960 by Hoffmann–La Roche, who soon followed with diazepam (Valium) in 1963. Benzodiazepines (BZDs) are central nervous system depressants, or tranquilizers. In contrast, drugs that induce cytochrome P450 enzymes, such as St John's wort, the antibiotic rifampicin, and the anticonvulsants carbamazepine and phenytoin, accelerate elimination of many benzodiazepines and decrease their action.

In the UK, both clobazam and clonazepam are second-line choices for treating many forms of epilepsy. Benzodiazepines work by increasing the effectiveness of the endogenous chemical, GABA, to decrease the excitability of neurons. [107][109] This meta-analysis found that long-term use of benzodiazepines was associated with moderate to large adverse effects on all areas of cognition, with visuospatial memory being the most commonly detected impairment. All Rights Reserved. A Brief History Of Benzodiazepines - Benzodiazepine Information Coalition Overall, benzodiazepines should be used short-term as they can lead to tolerance, abuse, dependence (addiction), withdrawal and possible fatal overdose when combined with opioids.

Abrupt withdrawal can be dangerous and lead to excitotoxicity, causing damage and even death to nerve cells as a result of excessive levels of the excitatory neurotransmitter glutamate. Other reactions due to IV administration may include: Some benzodiazepines (diazepam, chlordiazepoxide) have active metabolites that remain in the system for an extended period (long-acting), and this can be problematic for patients, especially older patients. This method of sedation is common for outpatient surgery or procedures that allow the patient to return home the same day, for example, endoscopy or colonoscopy procedures, wisdom tooth extractions, biopsies, and uncomplicated surgical procedures lasting less than one hour.
