Effect of Eszopiclone on Sleep Disturbance and Pain in Cancer

2014-08-27 03:43:00 | BioPortfolio


To assess the effectiveness of Lunesta on cancer patients who have received chemotherapy and who require patient controlled analgesia (PCA), specifically to assess whether Lunesta will:

- improve sleep thereby decreasing need for opiates via PCA

- improve sleep thereby decreasing pain by self report

- improve sleep thereby decreasing fatigue by self report


Pain and fatigue are the most common symptom complaints of cancer patients. Although dramatic improvements have come about in recognizing and treating cancer related pain, less progress has been made in treating fatigue. Interventions to improve sleep may offer benefit in terms of pain and fatigue.

One of the less commonly recognized side effects of opiate use is sleep disruption.

Experimentally-induced sleep disruption lowers the threshold for detection of painful stimuli. Thus, although opiates are obviously helpful for pain, they do so at certain "costs": they increase next day fatigue, constipation, and have other side effects; they disrupt sleep which further increases next day fatigue; and finally, by virtue of their sleep disruptive properties, they lower the threshold for pain stimuli.

Cancer patients requiring chemotherapy commonly require PCA because of oral mucositis. The objective of this study is to assess whether opiate usage may be reduced and complaints of fatigue and pain be lessened if patients had better sleep.

Medical and Biotech [MESH] Definitions


Disorders characterized by impairment of the ability to initiate or maintain sleep. This may occur as a primary disorder or in association with another medical or psychiatric condition.

Movements or behaviors associated with sleep, sleep stages, or partial arousals from sleep that may impair sleep maintenance. Parasomnias are generally divided into four groups: arousal disorders, sleep-wake transition disorders, parasomnias of REM sleep, and nonspecific parasomnias. (From Thorpy, Sleep Disorders Medicine, 1994, p191)

Conditions characterized by disturbances of usual sleep patterns or behaviors. Sleep disorders may be divided into three major categories: DYSSOMNIAS (i.e. disorders characterized by insomnia or hypersomnia), PARASOMNIAS (abnormal sleep behaviors), and sleep disorders secondary to medical or psychiatric disorders. (From Thorpy, Sleep Disorders Medicine, 1994, p187)

Dyssomnias (i.e., insomnias or hypersomnias) associated with dysfunction of internal sleep mechanisms or secondary to a sleep-related medical disorder (e.g., sleep apnea, post-traumatic sleep disorders, etc.). (From Thorpy, Sleep Disorders Medicine, 1994, p187)
