Patients with insomnia often feel groggy during the whole day and due to the sleep-deprivation of the previous night, it becomes quite a big task to focus on any task they take up. Scientific studies suggest that zolpidem, the nonbenzodiazepine drug of imidazopyridine class is an effective medicinal compound which can provide relief from the sleep-deprived state. The medication enables the central nervous system to generate the sleep signals by increasing the GABA effects. Unfortunately, zolpidem is a generic medicinal drug which is not easily available for commercial trade. But, people can buy the same drug under the brand name of Ambien.  The sleep-inducing medicine—Ambien pills cost cheaper than the other brands of generic zolpidem and easily available from any online drug store. Usually, the medication is available from the physical pharmacies on showing a doctor’s prescription but some online drug stores possess certain certificates which entitle them to offer the medication without prescription and insomniac patients can buy Ambien pills without any hassle.
