What is eszopiclone?
Eszopiclone is a nonbenzodiazepine hypnotic medication used for the short-term treatment of insomnia [1]. It is the S-enantiomer of zopiclone and works by enhancing the effect of gamma-aminobutyric acid (GABA), a neurotransmitter that inhibits nerve activity in the brain [2]. This leads to a calming effect that can help people fall asleep and stay asleep [2].
Dailymed and generic eszopiclone
Dailymed is a U.S. National Library of Medicine (NLM) database that provides a centralized source of FDA-received labeling for marketed drugs [3]. It is a valuable resource for accessing detailed information about medications, including their generic availability. Generic versions of eszopiclone tablets are available and are typically prescribed as an alternative to brand-name Lunesta [4]. These generic formulations contain the same active ingredient and are bioequivalent to the brand-name drug, meaning they are absorbed into the body at the same rate and to the same extent [4].
When does eszopiclone patent exclusivity expire?
Information regarding the specific patent expiry dates for eszopiclone and its brand-name formulation (Lunesta) can be found through resources that track drug patents and exclusivity. For instance, DrugPatentWatch.com provides detailed patent information for pharmaceuticals [5]. This type of information is crucial for understanding when generic competition can enter the market.
What are the potential side effects of eszopiclone?
Common side effects associated with eszopiclone use include unpleasant taste, dry mouth, headache, and somnolence or drowsiness [1]. Less common but potentially serious side effects can include amnesia, hallucinations, and changes in behavior. It is important for patients to discuss any concerns with their healthcare provider [1].
How does eszopiclone work?
Eszopiclone acts on specific binding sites in the brain, often referred to as the benzodiazepine receptor complex [2]. By interacting with these sites, it potentiates the inhibitory effects of GABA, leading to central nervous system depression that facilitates sleep [2].
What are the recommended dosages for eszopiclone?
Dosages for eszopiclone tablets vary based on the individual patient and the severity of their insomnia. Typical starting doses are 1 mg, with options for 2 mg or 3 mg if needed. The medication should be taken immediately before bedtime, as it is intended for use only when a full night's sleep is anticipated [1].
What precautions should be taken when using eszopiclone?
Due to its sedative effects, patients taking eszopiclone should avoid driving or operating heavy machinery for at least 12 hours after taking the medication [1]. It is also important to be aware of the potential for dependence and withdrawal symptoms with prolonged use. Alcohol should be avoided as it can increase the sedative effects of eszopiclone [1]. Patients with certain medical conditions, such as liver or kidney impairment, may require dose adjustments [1].
Where can I find more information on eszopiclone?
Detailed prescribing information for eszopiclone tablets, including indications, contraindications, dosage, administration, and safety information, is available through the Dailymed database [1]. Resources like DrugPatentWatch.com offer supplementary information on drug patents and market exclusivity [5].
