Insomnia: Medications and Medical Therapies

There are numerous possible medications to treat insomnia. Generally, it is advised that they should not be used as the only therapy and that treatment is more successful if combined with non-medical therapies. In a study, it was noted that when sedatives were combined with behavioral therapy, more patients were likely to wean off the sedatives than if sedatives were used alone.

* Benzodiazepine sedatives: six of these sedative drugs have been used to treat insomnia. There are reports of subjective improvement of quality and quantity of sleep when using these medications. These include temazepam (Restoril), flurazepam (Dalmane), triazolam (Halcion), estazolam (ProSom, Eurodin), lorazepam (Ativan), and clonazepam (Klonopin).

* Nonbenzodiazepine sedatives: These include eszopiclone (Lunesta), zaleplon (Sonata), and zolpidem (Ambien).

* Melatonin: Melatonin is secreted by the pineal gland, a pea-sized structure at the center of your brain. Melatonin is produced during the dark hours of the day-night cycle (circadian rhythm). Melatonin levels in the body are low during daylight hours. The pineal gland responds to darkness by increasing melatonin levels in the body. This process is thought to be integral to maintaining circadian rhythm. At night, melatonin is produced to help your body regulate your sleep-wake cycles. The amount of melatonin produced by your body seems to decrease as you get older. Melatonin may be beneficial in patients with circadian rhythm problems.

* Ramelteon (Rozerem) is a prescription drug that stimulates melatonin receptors. Ramelteon promotes the onset of sleep and helps normalize circadian rhythm disorders. Ramelteon is approved by the Food and Drug Administration (FDA) for treatment of insomnia characterized by difficulty falling asleep.

* Some antidepressants [for example, amitriptyline (Elavil, Endep) and trazodone (Desyrel)] have been used for the treatment of insomnia in patients with co-existing depression because of some sedative properties. Generally, they may not be helpful for insomnia in people without depression.

* Antihistamines with sedative properties [for example, diphenhydramine (Benadryl) or doxylamine] have also been used in treating insomnia as they may induce drowsiness, but they do not improve sleep and should not be used to treat chronic insomnia.

* Valeriana officinalis (Valerian) is a popular herbal medication used in the United States for treating insomnia, however, to date there are no convincing studies to show any real benefit in patients with chronic insomnia.
