“We’re pleased that the prescribing information for BELSOMRA includes findings from Merck’s first dedicated study of an insomnia medication in patients with mild-to-moderate Alzheimer’s disease.”—Dr. W. Joseph Herring

In an insomnia study in adults with mild to moderate Alzheimer’s disease, people achieved longer total sleep time when taking BELSOMRA compared to those taking placebo.

BELSOMRA is thought to inhibit the action of orexin, one of the wake neurotransmitters that play a role in the wake-sleep cycle.

BELSOMRA is a prescription medicine that is thought to target and inhibit the action of orexin.

Orexin is a neurotransmitter that plays a role in the wake-sleep cycle. BELSOMRA is thought to work by blocking orexin from sending wake signals to other parts of the brain, which could be keeping you from sleeping.
