Non-Benzodiazepine Hypnotics are a class of medications used primarily to treat insomnia, acting on the GABA-A receptor complex to induce sleep with fewer side effects and lower potential for dependence than traditional benzodiazepines. They include drugs like zolpidem, zaleplon, and eszopiclone, characterized by their selective action and shorter half-lives, making them suitable for short-term management of sleep disorders.
