Sleep Maintenance

LUNESTA® (eszopiclone) improved sleep maintenance vs baseline in a 6-month study1-2

Study Design
A randomized, double-blind, placebo-controlled, 6-month trial of nightly administration of either LUNESTA 3 mg (n=593) or placebo (n=195) in adults (aged 21 to 69 years) with primary chronic insomnia. The primary endpoint was patient-reported average sleep latency over the last 3 months (Months 4 to 6) during the double-blind period, which was significantly improved vs placebo. WASO and total sleep time (TST) were secondary endpoints.

WASO measures how much time a patient spends awake during the night after initially falling asleep.

Important Safety Information & Indication

LUNESTA® (eszopiclone) is contraindicated in patients with a known hypersensitivity to eszopiclone.  Hypersensitivity reactions include anaphylaxis and angioedema.

LUNESTA, like other hypnotics, has CNS-depressant effects.  Because of the rapid onset of action, LUNESTA should only be taken immediately prior to going to bed or after the patient has gone to bed and has experienced difficulty falling asleep.  Patients should be cautioned against engaging in hazardous occupations requiring complete mental alertness or motor coordination after taking LUNESTA, including potential impairment of the performance of such activities that may occur the day following ingestion of LUNESTA. The risk of next-day psychomotor impairment is increased if LUNESTA 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.

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.

Rare cases of angioedema and symptoms suggesting anaphylaxis have been reported in patients after taking the first or subsequent doses of sedative-hypnotics, including LUNESTA.  Patients who experience such reactions 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.  These changes include decreased inhibition, bizarre behavior, agitation, hallucinations and confusion.  Complex behaviors such as “sleep driving”, preparing and eating food, making phone calls, or having sex while not fully awake, with amnesia for the event, have been reported.  The use of alcohol and other CNS depressants appears to increase the risk of such behaviors.  The emergence of any new behavioral sign or symptom requires immediate evaluation. LUNESTA should not be taken together with alcohol or other sedative hypnotics.

Due to the concern of impaired motor, cognitive performance and increased sensitivity in elderly patients the dose should not exceed 2 mg in elderly or debilitated patients.

Sedative/hypnotic drugs should be administered with caution to patients exhibiting signs and symptoms of depression.  In primarily depressed patients, worsening of depression, including suicidal thoughts and actions (including completed suicides) have been reported in association with the use of sedative/hypnotics.

Sedative hypnotics have produced withdrawal signs and symptoms following abrupt discontinuation.  Use of benzodiazepines and similar agents may lead to physical and psychological dependence. The risk of abuse and dependence increases with the dose and duration of treatment and concomitant use of other psychoactive drugs. LUNESTA is a Schedule IV controlled substance. Patients with a history of alcohol or drug abuse or history of psychiatric disorders should be under careful surveillance when receiving LUNESTA or any other hypnotic.

LUNESTA should be used with caution in patients with hepatic impairment, impaired respiratory function, impaired drug metabolism or hemodynamic responses.

In clinical trials, the most commonly observed adverse reactions (incidence ≥2%) were unpleasant taste, headache, somnolence, infection, dizziness, dry mouth, rash, anxiety, and hallucinations.

LUNESTA® (eszopiclone) is indicated for the treatment of insomnia. In controlled outpatient and sleep laboratory studies, LUNESTA administered at bedtime decreased sleep latency and improved sleep maintenance.
