Overview
Eszopiclone is a hypnotic agent/nonbenzodiazepine hypnotic agent that is a pyrrolopyrazine derivative of the cyclopyrrolone class. The chemical name of eszopiclone is (+)-4-Methyl-1-piperazinecarboxylic acid 6-(5-chloro-2-pyridinyl)-6,7-dihydro-7-oxo-5 H pyrrolo[3,4- b ]pyrazin-5-(S)-yl ester. Its molecular weight is 388.81, and its molecular formula is C 17 H 17 ClN 6 O 3 . Eszopiclone has a single chiral center with an ( S )-configuration. It has the following chemical structure: Eszopiclone USP is a white to slight yellowish powder. Eszopiclone USP is soluble in methylene chloride and dilute hydrochloric acid; practically insoluble in water and in alcohol. Eszopiclone is formulated as film-coated tablets for oral administration. Eszopiclone tablets, USP contain 1 mg, 2 mg, or 3 mg eszopiclone USP and the following inactive ingredients: anhydrous dibasic calcium phosphate, croscarmellose sodium, colloidal silicon dioxide, hypromellose lactose monohydrate, magnesium stearate, microcrystalline cellulose, polyethylene glycol, titanium dioxide, and triacetin. In addition, both the 1 mg and 3 mg tablets contain FD&C Blue #2/indigo carmine aluminium lake. eszopiclonestructure
How to use
Use the lowest effective dose for the patient. • Use the lowest dose effective for the patient ( 2 ) • Recommended initial dose is 1 mg, immediately before bedtime, with at least 7 to 8 hours remaining before the planned time of awakening. May increase dose if clinically indicated, to a maximum of 3 mg ( 2.1 ) • Geriatric or debilitated patients: Dose should not exceed 2 mg ( 2.2 ) • Patients with severe hepatic impairment, or taking potent CYP3A4 inhibitors: Dose should not exceed 2 mg ( 2.3 ) • Do not take with or immediately after a meal ( 2.5 ) 2.1 Dosage in Adults The recommended starting dose is 1 mg. Dosing can be raised to 2 mg or 3 mg if clinically indicated. In some patients, the higher morning blood levels of eszopiclone tablets following use of the 2 mg or 3 mg dose increase the risk of next day impairment of driving and other activities that require full alertness [ see Warnings and Precautions (5.1) ]. The total dose of eszopiclone tablets should not exceed 3 mg, once daily immediately before bedtime [ see Warnings and Precautions (5.6) ]. 2.2 Geriatric or Debilitated Patients The total dose of eszopiclone tablets should not exceed 2 mg in elderly or debilitated patients. 2.3 Patients with Severe Hepatic Impairment, or Taking Potent CYP3A4 Inhibitors In patients with severe hepatic impairment, or in patients coadministered eszopiclone tablets with potent CYP3A4…
Side effects
The following are described in more detail in the Warnings and Precautions section of the label: • Complex Sleep Behaviors [see Boxed Warning and Warnings and Precautions (5.1) ] • CNS Depressant Effects and Next-Day Impairment [see Warnings and Precautions (5.2) ] • Need to Evaluate for Comorbid Diagnoses [see Warnings and Precautions (5.3) ] • Severe Anaphylactic and Anaphylactoid Reactions [see Warnings and Precautions (5.4) ] • Abnormal Thinking and Behavioral Changes [see Warnings and Precautions (5.5) ] • Withdrawal Effects [see Warnings and Precautions (5.6) ] • Timing of Drug Administration [see Warnings and Precautions (5.7) ] • Special Populations [see Warnings and Precautions (5.8) ] Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in clinical practice. The premarketing development program for eszopiclone tablets included eszopiclone exposures in patients and/or normal subjects from two different groups of studies: approximately 400 normal subjects in clinical pharmacology/pharmacokinetic studies, and approximately 1550 patients in placebo-controlled clinical effectiveness studies, corresponding to approximately 263 patient-exposure years.

Warnings
Important safety information
WARNING: COMPLEX SLEEP BEHAVIORS WARNING: COMPLEX SLEEP BEHAVIORS Complex sleep behaviors including sleep-walking, sleep-driving, and engaging in other activities while not fully awake may occur following use of eszopiclone tablets. Some of these events may result in serious injuries, including death. Discontinue eszopiclone tablets immediately if a patient experiences a complex sleep behavior [see Contraindications (4) and Warnings and Precautions (5.1) ]. WARNING: COMPLEX SLEEP BEHAVIOUR See full prescribing information for complete boxed warning. Complex sleep behaviors including sleep-walking, sleep-driving, and engaging in other activities while not fully awake may occur following use of eszopiclone tablets. Some of these events may result in serious injuries, including death. Discontinue eszopiclone tablets immediately if a patient experiences a complex sleep behavior ( 4 , 5.1 ).
Interactions
7 DRUG INTERACTIONS • CNS Depressants Additive CNS-depressant effects with combination use. Use with ethanol causes additive psychomotor impairment ( 7.1 ) • Rifampicin Combination use may decrease exposure and effects of eszopiclone tablets ( 7.2 ) • Ketoconazole Combination use increases exposure and effect of eszopiclone tablets. Dose reduction of eszopiclone tablet is needed ( 7.2 ) 7.1 CNS Active Drugs Ethanol: An additive effect on psychomotor performance was seen with coadministration of eszopiclone and ethanol [see Warnings and Precautions (5.1 , 5.2) ]. Olanzapine: Coadministration of eszopiclone and olanzapine produced a decrease in DSST scores. The interaction was pharmacodynamic; there was no alteration in the pharmacokinetics of either drug. 7.2 Drugs that Inhibit or Induce CYP3A4 Drugs that Inhibit CYP3A4 (Ketoconazole) CYP3A4 is a major metabolic pathway for elimination of eszopiclone. The exposure of eszopiclone was increased by coadministration of ketoconazole, a potent inhibitor of CYP3A4. Other strong inhibitors of CYP3A4 (e.g., itraconazole, clarithromycin, nefazodone, troleandomycin, ritonavir, nelfinavir) would be expected to behave similarly. Dose reduction of eszopiclone tablet is needed for patient co-administered eszopiclone tablets with potent CYP3A4 inhibitors [see Dosage and Administration (2.3) ] . Drugs that Induce CYP3A4 (Rifampicin) Racemic…
