Zolpidem , which is sold, among other things, under the brand name Ambien, is a drug that is mainly used for short-term treatment of sleep problems.   Guidelines recommend that it be used only after counseling and behavioral changes have been tested.    It reduces the time to sleep for about 15 minutes and at larger doses helps people sleep longer.  It is taken by mouth and is found in conventional or sublingual tablets and oral sprays. 
Common side effects include daytime sleepiness, headaches, nausea and diarrhea.  Other side effects include memory problems, hallucinations and addictions.  The recommended dose was reduced in 2013 due to deterioration the next morning.  In addition, driving the next morning is recommended with neither higher doses nor the long-acting formulation.  While flumazenil may reverse the effects of zolpidem, supportive care is usually all that is recommended in case of overdose. 
Zolpidem is a non-benzodiazepine Z drug that acts as a sedative and hypnotic.   Zolpidem is a type A GABA receptor agonist of the imidazopyridine class.  It works by increasing GABA effects in the central nervous system by binding to GABAA receptors at the same site as benzodiazepines.  It generally has a half-life of two to three hours.  However, this is increased in those with liver problems. 
Zolpidem was approved for medical use in the United States in 1992.  It became available as a generic medication in 2007.  In the United States, it has a monthly cost of approximately $ 8 for immediate release and $ 66 for controlled-release medicine , from and with 2017.

Zopiclone is known as a ”Z drug”. Other Z drugs include zaleplon and zolpidem and were initially thought to be less addictive than benzodiazepines. However, this assessment has shifted somewhat in recent years when cases of abuse and habit have been presented. Zopiclone is recommended to be taken in the short term, usually not more than a week or two.  Daily or continuous use of the drug is not usually recommended and caution should be taken when using the compound with antidepressants, sedatives or other drugs affecting the central nervous system.
