Final answer:
Zolpidem (Ambien) is a depressant psychoactive drug classified as a sedative-hypnotic, desirable for its efficacy in initiating sleep with relatively fewer side effects and lower risk of dependence, though non-pharmacological treatments may be preferable for long-term insomnia management.
Step-by-step explanation:
Zolpidem, known by the brand name Ambien, is classified as a depressant type of psychoactive drug. It falls into a category of medications known as sedative-hypnotics and is specifically designed to combat insomnia by calming the brain, reducing anxious feelings, and promoting sleepiness. As a non-benzodiazepine with a fast onset of action, zolpidem is particularly desirable because it tends to have fewer side effects and a lower risk of dependence compared to older benzodiazepines. However, while it may be effective for initiating sleep, concerns regarding next-day impairment and potential for abuse do exist. Studies have shown that non-pharmacological treatments like cognitive behavioral therapy can be more effective for long-term management of insomnia.
