Summary

This trial tests daridorexant, a medication that helps people sleep better, on those who have trouble sleeping and frequently wake up at night to urinate. It works by calming brain activity to improve sleep. Daridorexant is a newly approved treatment for insomnia.

Who is the study for?
This trial is for men and women over 55 who have trouble sleeping (insomnia) and need to urinate at least three times a night (nocturia). They should be able to communicate clearly, understand the study's requirements, have an ISI© score ≥ 13, own a smartphone, and have had these sleep issues for at least three months.
What is being tested?
The study is testing Daridorexant's effectiveness in improving sleep among those with insomnia and frequent nighttime urination. Participants will either receive Daridorexant or a placebo (a pill without active medication), to compare outcomes between the two groups.
What are the potential side effects?
While specific side effects of Daridorexant are not listed here, common ones may include drowsiness during the day, headache, dizziness or lightheadedness. Side effects can vary from person to person.

Mechanism Of Action

Other Research
The most common treatments for insomnia include benzodiazepines, non-benzodiazepine hypnotics (e.g., zolpidem), melatonin receptor agonists (e.g., ramelteon), and Dual Orexin Receptor Antagonists (DORAs) like daridorexant. Benzodiazepines and non-benzodiazepine hypnotics enhance the effect of the neurotransmitter GABA, promoting sedation. Melatonin receptor agonists mimic the sleep-regulating hormone melatonin, aiding in sleep onset. DORAs, such as daridorexant, work by blocking orexin receptors, which play a role in wakefulness, thereby promoting sleep. Understanding these mechanisms helps patients and doctors choose the most appropriate treatment based on the specific sleep issues and potential side effects, leading to better management of insomnia.
