Pharmacologic treatment of disturbed sleep in the elderly.

Disturbed sleep is common in the elderly, who, as a group, take a disproportionately large number of hypnotic medications. Benzodiazepine hypnotics, as well as the newer benzodiazepine receptor agonists, are the primary treatments for these late-life sleep disorders and are effective and safe when used within recommended prescribing guidelines. The elderly also receive other psychiatric medications to induce sleep, although these are off-label uses not well supported by research literature. There is also no literature support for the use of over-the-counter sleep preparations, although both melatonin and a melatonin receptor agonist appear to be moderately effective and safe. Prescribing guidelines for the elderly continue to emphasize short-term, low-dose use, with short-half-life medications. Hypnotic drugs should be used in conjunction with nonmedication treatments, including appropriate sleep hygiene practice, and treatment of other medical or psychiatric causes of disturbed sleep.
