Drug May Offer New Approach to Treating Insomnia

29.11.2012
A new drug may bring help for people with insomnia, according to a study published in the November 28, 2012, online issue of Neurology®, the medical journal of the American Academy of Neurology.

The drug, suvorexant, blocks the chemical messengers in the brain called orexins, which regulate wakefulness. Other drugs for insomnia affect different brain receptors.

Taking the drug suvorexant increased the amount of time people spent asleep during the night, according to the study. The study involved 254 people ages 18 to 64 who were in good physical and mental health but had insomnia that was not due to another medical condition.

The participants took either the drug or a placebo for four weeks, then switched to the other treatment for another four weeks. The participants spent the night in a sleep laboratory with their sleep monitored on the first night with each treatment and then again in the fourth week of each treatment.

While taking the drug, participants’ “sleep efficiency,” which reflects the total amount of time they slept during a fixed, eight hour time in bed, improved by 5 to 13 percent compared to those taking the placebo. They also experienced 21 to 37 fewer minutes awake during the night after they had fallen asleep than those who took the placebo.

“This study provides evidence that suvorexant may offer a successful alternative strategy for treating insomnia,” said study author W. Joseph Herring, MD, PhD, of North Wales, Penn., Executive Director of Clinical Research with Merck, the maker of suvorexant, and a member of the American Academy of Neurology. “Suvorexant was generally well-tolerated, and there were no serious side effects.”

Herring said larger, longer studies have recently been conducted on suvorexant, along with studies to determine whether the drug could be safe and effective for elderly people, who make up a large percentage of those suffering from insomnia.

Merck has submitted a new drug application for the treatment with the U. S. Food and Drug Administration.

The study was funded by Merck Research Laboratories.

The American Academy of Neurology, an association of more than 25,000 neurologists and neuroscience professionals, is dedicated to promoting the highest quality patient-centered neurologic care. A neurologist is a doctor with specialized training in diagnosing, treating and managing disorders of the brain and nervous system such as Alzheimer’s disease, stroke, migraine, multiple sclerosis, brain injury, Parkinson’s disease and epilepsy.

Im Focus: Fizzy soda water could be key to clean manufacture of flat wonder material: Graphene

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.

As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...

Im Focus: Exotic quantum states made from light: Physicists create optical “wells” for a super-photon

Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.

Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...

Im Focus: Circular RNA linked to brain function

For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.

While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...

Im Focus: RAVAN CubeSat measures Earth's outgoing energy

An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.

The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...

Im Focus: Scientists shine new light on the “other high temperature superconductor”

A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.

Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
