The most common brand names of this drug are Ambien and Ambien CR. It is also known under the generic name of Zolpidem. The patent for Zolpidem Tartrate held by the French manufacturer, Sanofi-Aventis, expired in April, 2007. This brought down the retail price which is one of the reasons why Ambien is currently one of the fifteen highest selling branded drugs in the USA.

Because some concerns have been raised about the common use of sedative-hypnotic drugs to help people sleep, the Food and Drugs Authority (FDA) and other regulatory authorities around the world have required stronger warnings to be printed on the labelling. But, other than this precautionary measure, Ambien in all its forms is freely available by prescription, over-the-counter in some countries and for you to buy online.
