benzodiazepine receptor agonist

A benzodiazepine receptor agonist is a type of medication that binds to specific sites on the brain’s GABA-A receptors, enhancing the calming effect of a neurotransmitter called GABA. This action helps to reduce anxiety, promote sleep, and relax muscles. These drugs are commonly prescribed for anxiety disorders, insomnia, and certain seizures. The term "agonist" means they activate these receptors, increasing their inhibitory effects. While effective, they can also cause side effects like drowsiness and dependence if used long-term.
