What is Hetlioz
Hetlioz is a medication that binds to and activates the melatonin receptor in the brain. Hetlioz resembles the natural melatonin hormone produced by our body during sleep. Melatonin is a hormone (chemical) produced in the pineal gland from the amino acid tryptophan and is shown to help regulate sleep. Stimulation of melatonin receptors helps the body maintain normal circadian rhythms.
Melatonin supplements, containing various concentrations of melatonin, are available over-the-counter.Hetlioz requires doctor’s prescription and it is not a supplement. Hetlioz is a melatonin receptor agonist and thought to have better therapeutic effects in patients with non-24-hour sleep-wake disorder (Non-24-Hour Disorder) in the blind than natural melatonin as it binds with much higher affinity with melatonin receptors. There is little scientific data supporting a beneficial effect of melatonin supplements in the treatment of this disorder. What is Hetlioz used for
Hetlioz is indicated for the treatment of non-24-hour sleep-wake disorder in completely blind individuals. Non-24-hour sleep-wake disorder is a body clock disorder in totally blind persons caused by the inability to perceive light to maintain a normal sleep schedule. Those with this disorder have problems staying asleep or falling asleep. Hetlioz has been shown to correct this abnormality as well as improve sleep. Approximately 100,000 people in the United States have this condition and Hetlioz is the first FDA treatment approved for this disorder.
How well does Hetlioz work
The effectiveness of Hetlioz was evaluated in totally blind individuals with non-24-hour sleep-wake disorder in two studies:
·n study 1:84 patients were placed in a group either taking Hetlioz 20 mg or placebo one hour before bedtime, at the same time every night for 6 months. In a second study 20 patients were randomly withdrawn after being treated for 12 weeks with Hetlioz 20 mg one hour before bedtime, at the same time every night. They were placed in a group either receiving Hetlioz 20 mg for 8 weeks or placebo. In both studies Hetlioz was more effective than placebo. Hetlioz treatment resulted in greater than 45 minutes increase in nighttime sleep and greater than 45 minutes decrease in daytime sleep.
