Ambien, the brand name for zolpidem tartrate, is manufactured by Sanofi-Aventis [1]. However, multiple companies produce generic versions of zolpidem tartrate [2].
Who else makes zolpidem?
Generic versions of zolpidem are available from various pharmaceutical companies, including but not limited to Teva Pharmaceuticals, Mylan, and Accord Healthcare [2]. The availability of generic options means that patients and healthcare providers can access zolpidem tartrate from a range of manufacturers.
When did Ambien go generic?
The patent protection for Ambien, originally developed by Pharmacia (later acquired by Pfizer), expired, allowing for the introduction of generic versions. The first generic versions of zolpidem tartrate began appearing on the market around 2007 [3].
What is zolpidem used for?
Zolpidem is a sedative-hypnotic medication primarily prescribed for the short-term treatment of insomnia [4]. It works by slowing down the activity in the brain, which helps individuals fall asleep and stay asleep [4]. It is typically prescribed for individuals who have difficulty initiating sleep [4].
What are the side effects of zolpidem?
Common side effects associated with zolpidem use include drowsiness, dizziness, and diarrhea [4]. More serious side effects can occur, such as complex sleep behaviors like sleepwalking, sleep-driving, and engaging in other activities while not fully awake, with no memory of the event afterward [4]. It is important for patients to take zolpidem exactly as prescribed and to avoid activities requiring full alertness afterward [4].
How is zolpidem regulated?
Zolpidem tartrate is classified as a Schedule IV controlled substance by the U.S. Drug Enforcement Administration (DEA) [5]. This classification indicates that the drug has a potential for abuse or dependence, but a lower potential compared to Schedule III drugs [5]. Its manufacturing, distribution, and prescribing are subject to federal regulations designed to prevent diversion and misuse [5].
What is the difference between Ambien and generic zolpidem?
The active ingredient in both Ambien and its generic versions is zolpidem tartrate [1][2]. Generic medications are required to be bioequivalent to their brand-name counterparts, meaning they are expected to have the same active ingredient, dosage form, strength, and route of administration [6]. While the inactive ingredients may differ, the therapeutic effect should be the same [6]. The primary difference typically lies in the brand name and cost [6].
Where can I find more information on zolpidem patents?
