benzodiazepine
Pronunciation: ben-zoh-dy-AZ-uh-peen
A class of psychoactive drugs primarily used for anxiety, sleep disorders, and seizures, known for their potential for dependence and tolerance.
Full Definition
Benzodiazepines are a class of psychoactive medications that enhance the effect of the neurotransmitter GABA at the GABA-A receptor, resulting in sedative, hypnotic, anxiolytic, anticonvulsant, and muscle relaxant properties. Common examples include lorazepam, diazepam, and alprazolam. While effective for short-term management of anxiety and insomnia, these medications carry significant risks including tolerance, physical dependence, cognitive impairment, and potentially dangerous withdrawal syndrome. Long-term use is generally discouraged due to these risks and diminishing therapeutic benefits.
Usage
Usage note: Commonly abbreviated as 'benzo' in informal clinical contexts.
