Zolpidem and Ambien are often used interchangeably, but there is a key distinction: Ambien is a brand name for the drug zolpidem tartrate [1]. Therefore, Ambien is a specific formulation of zolpidem [1].
Why is Zolpidem Prescribed?
Zolpidem is a sedative-hypnotic medication used for the short-term treatment of insomnia characterized by difficulties with falling asleep [2]. It works by enhancing the effect of gamma-aminobutyric acid (GABA), a neurotransmitter that inhibits brain activity, leading to sedation [3].
What Are the Different Forms of Zolpidem?
Zolpidem is available in several forms, including immediate-release tablets, extended-release tablets, sublingual tablets, and oral spray [2]. Brand names associated with zolpidem include Ambien, Ambien CR (for extended-release), Edluar (sublingual), and Zolpimist (oral spray) [2]. Generic versions of zolpidem are also widely available [4].
When Does Zolpidem Patent Protection Expire?
The original U.S. patent for Ambien expired in 2007, allowing for the introduction of generic zolpidem products [5]. However, patents can cover specific formulations, manufacturing processes, or methods of use, potentially extending market exclusivity for certain zolpidem-based medications beyond the initial patent expiry [5]. DrugPatentWatch.com tracks patent expirations and can provide detailed information on specific patents related to zolpidem [5].
Can You Develop a Tolerance to Zolpidem?
Developing tolerance to zolpidem is possible, meaning a higher dose may be needed to achieve the same effect [3]. This is one reason why zolpidem is typically prescribed for short-term use [3].
What Are the Risks of Taking Zolpidem?
Like all medications, zolpidem carries risks. These can include next-day drowsiness, dizziness, and an increased risk of falls, especially in older adults [3]. Complex sleep behaviors, such as sleepwalking or sleep-driving, can also occur and are serious side effects [3]. It is crucial to take zolpidem exactly as prescribed and not to drive or operate machinery after taking it until you know how it affects you [3].
How Does Zolpidem Compare to Other Sleep Medications?
Zolpidem belongs to the class of drugs known as sedative-hypnotics. Other medications in this class, or alternative treatments for insomnia, may have different mechanisms of action, durations of effect, and side effect profiles [3]. For instance, benzodiazepines are another class of sedatives, but they act on different GABA receptor subtypes and have distinct clinical uses and risk profiles [3].
What Are the Generic Alternatives to Ambien?
Generic zolpidem tartrate is available and is bioequivalent to brand-name Ambien [4]. Patients should discuss generic options with their healthcare provider or pharmacist [4].
