(Bold for FDA approved)
How Zolnite works• May bind selectively to a subtype of the benzodiazepine receptor, the alpha 1 isoform
• May enhance GABA inhibitory actions that provide sedative hypnotic effects more selectively than other actions of GABA
• Boosts chloride conductance through GABA-regulated channels
• Inhibitory actions in sleep centers may provide sedative hypnotic effects
• Generally takes effect in less than an hour
Notable Side Effects• Unpleasant taste
• Sedation
• Dizziness
• Dose-dependent amnesia
• Nervousness
• Dry mouth, headache
Life Threatening Side Effects• Respiratory depression, especially when taken with other CNS depressants in overdose
• Rare angioedema

common
• Wait
• To avoid problems with memory, take eszopiclone only if planning to have a full night’s sleep
• Lower the dose
• Switch to a shorter-acting sedative hypnotic
• Administer flumazenil if side effects are severe or life-threatening
• 2–3 mg at bedtime
Dosage Forms• Tablet 1 mg, 2 mg, 3 mg
• No development of tolerance was seen in studies up to 6 months
• Eszopiclone is a Schedule IV drug
• Some patients could develop dependence and/or tolerance with drugs of this class; risk may be theoretically greater with higher doses
• History of drug addiction may theoretically increase risk of dependence
Renal Impairment• Dose adjustment not generally necessary
Hepatic Impairment• Dose adjustment not generally recommended for mild-to-moderate hepatic impairment
• For severe impairment, recommended initial dose 1 mg at bedtime; maximum dose 2 mg at bedtime
Cardiac Impairment• Dosage adjustment may not be necessary
Elderly• May be more susceptible to adverse effects
• Initial dose 1 mg at bedtime; maximum dose generally 2 mg at bedtime
Children and Adolescents• Safety and efficacy have not been established
• Long-term effects of eszopiclone in children/adolescents are unknown
• Should generally receive lower doses and be more closely monitored
Pregnancy• Effective June 30, 2015, the FDA requires changes to the content and format of pregnancy and lactation information in prescription drug labels, including the elimination of the pregnancy letter categories; the Pregnancy and Lactation Labeling Rule (PLLR or final rule) applies only to prescription drugs and will be phased in gradually for drugs approved on or after June 30, 2001
• Controlled studies have not been conducted in pregnant women
• Infants whose mothers took sedative hypnotics during pregnancy may experience some withdrawal symptoms
• Neonatal flaccidity has been reported in infants whose mothers took sedative hypnotics during pregnancy
Breast Feeding• Unknown if eszopiclone is secreted in human breast milk, but all psychotropics are assumed to be secreted in breast milk
• Recommended either to discontinue drug or bottle feed
