ESZOPICLONE- eszopiclone tablet, film coated
Lake Erie Medical DBA Quality Care Products LLC
Eszopiclone tablets are indicated for the treatment of insomnia. In controlled outpatient and sleep laboratory studies, eszopiclone tablets administered at bedtime decreased sleep latency and improved sleep maintenance.
The clinical trials performed in support of efficacy were up to 6 months in duration. The final formal assessments of sleep latency and maintenance were performed at 4 weeks in the 6-week study (adults only), at the end of both 2-week studies (elderly only) and at the end of the 6-month study (adults only).
Use the lowest effective dose for the patient.
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) ].
The total dose of eszopiclone tablets should not exceed 2 mg in elderly or debilitated patients.
In patients with severe hepatic impairment, or in patients coadministered eszopiclone with potent CYP3A4 inhibitors, the total dose of eszopiclone tablets should not exceed 2 mg [see Warning and Precautions (5.7) ].
Dosage adjustments may be necessary when eszopiclone tablets are combined with other CNS depressant drugs because of the potentially additive effects [see Warnings and Precautions (5.1)].
Taking eszopiclone tablets with or immediately after a heavy, high-fat meal results in slower absorption and would be expected to reduce the effect of eszopiclone tablets on sleep latency [see Clinical Pharmacology (12.3)].
Eszopiclone tablets are available in 1 mg, 2 mg and 3 mg strengths for oral administration.
Eszopiclone 3 mg tablets are dark blue, round, biconvex, film coated tablet, debossed with “L 36” on one side and plain on other side.
Eszopiclone 2 mg tablets are are white, round, biconvex, film coated tablet, debossed with “L 35” on one side and plain on other side.
Eszopiclone 1 mg tablets are light blue, round, biconvex, film coated tablet, debossed with “L 34” on one side and plain on other side.
Eszopiclone tablets are contraindicated in patients with known hypersensitivity to eszopiclone. Hypersensitivity reactions include anaphylaxis and angioedema [see Warnings and Precautions (5.3)].
Eszopiclone is a central nervous system (CNS) depressant and can impair daytime function in some patients at the higher doses (2 mg or 3 mg), even when used as prescribed. Prescribers should monitor for excess depressant effects, but impairment can occur in the absence of symptoms (or even with subjective improvement), and impairment may not be reliably detected by ordinary clinical exam (i.e., less than formal psychomotor testing). While pharmacodynamic tolerance or adaptation to some adverse depressant effects of eszopiclone may develop, patients using 3 mg eszopiclone should be cautioned against driving or engaging in other hazardous activities or activities requiring complete mental alertness the day after use.
Additive effects occur with concomitant use of other CNS depressants (e.g., benzodiazepines, opioids, tricyclic antidepressants, alcohol), including daytime use. Downward dose adjustment of eszopiclone and concomitant CNS depressants should be considered [see Dosage and Administration (2.4)].
The use of eszopiclone with other sedative-hypnotics at bedtime or the middle of the night is not recommended.
The risk of next-day psychomotor impairment is increased if eszopiclone is taken with less than a full night of sleep remaining (7-to 8 hours); if higher than the recommended dose is taken; if co-administered with other CNS depressants; or co-administered with other drugs that increase the blood levels of eszopiclone [see Dosage and Administration (2.3) and Clinical Studies (14.3)].
Because sleep disturbances may be the presenting manifestation of a physical and/or psychiatric disorder, symptomatic treatment of insomnia should be initiated only after a careful evaluation of the patient. The failure of insomnia to remit after 7 to 10 days of treatment may indicate the presence of a primary psychiatric and/or medical illness that should be evaluated . Worsening of insomnia or the emergence of new thinking or behavior abnormalities may be the consequence of an unrecognized psychiatric or physical disorder. Such findings have emerged during the course of treatment with sedative/hypnotic drugs, including eszopiclone. Because some of the important adverse effects of eszopiclone appear to be dose-related, it is important to use the lowest possible effective dose, especially in the elderly [see Dosage and Administration (2.1)].
Rare cases of angioedema involving the tongue, glottis or larynx have been reported in patients after taking the first or subsequent doses of sedative-hypnotics, including eszopiclone. Some patients have had additional symptoms such as dyspnea, throat closing, or nausea and vomiting that suggest anaphylaxis. Some patients have required medical therapy in the emergency department. If angioedema involves the tongue, glottis or larynx, airway obstruction may occur and be fatal. Patients who develop angioedema after treatment with eszopiclone should not be rechallenged with the drug.
A variety of abnormal thinking and behavior changes have been reported to occur in association with the use of sedative/hypnotics. Some of these changes may be characterized by decreased inhibition (e.g., aggressiveness and extroversion that seem out of character), similar to effects produced by alcohol and other CNS depressants. Other reported behavioral changes have included bizarre behavior, agitation, hallucinations, and depersonalization. Amnesia and other neuropsychiatric symptoms may occur unpredictably. In primarily depressed patients, worsening of depression, including suicidal thoughts and actions (including completed suicides), has been reported in association with the use of sedative/hypnotics.
Complex behaviors such as “sleep-driving” (i.e., driving while not fully awake after ingestion of a sedative-hypnotic, with amnesia for the event) have been reported. These events can occur in sedative-hypnotic-naïve as well as in sedative-hypnotic-experienced persons. Although behaviors such as sleep-driving may occur with eszopiclone alone at therapeutic doses, the use of alcohol and other CNS depressants with eszopiclone appears to increase therisk of such behaviors, as does the use of eszopiclone at doses exceeding the maximum recommended dose. Due to the risk to the patient and the community, discontinuation of eszopiclone should be strongly considered for patients who report a “sleep-driving” episode. Other complex behaviors (e.g., preparing and eating food, making phone calls, or having sex) have been reported in patients who are not fully awake after taking a sedative-hypnotic. As with sleep-driving, patients usually do not remember these events.
It can rarely be determined with certainty whether a particular instance of the abnormal behaviors listed above are drug-induced, spontaneous in origin, or a result of an underlying psychiatric or physical disorder. Nonetheless, the emergence of any new behavioral sign or symptom of concern requires careful and immediate evaluation.
Following rapid dose decrease or abrupt discontinuation of the use of sedative/hypnotics, there have been reports of signs and symptoms similar to those associated with withdrawal from other CNS-depressant drugs [see Drug Abuse and Dependence (9)].
