Does Quviviq work?

If you have insomnia, you may have trouble falling asleep or getting a full night’s rest. Sleeping problems can lead to difficulties functioning during the daytime and have unpleasant effects on your work, social, and family life. The good news is there are a number of sleep medications that your healthcare provider can recommend or prescribe. One of these medications is Quviviq (daridorexant) from Idorsia Pharmaceuticals. It is a newer drug that belongs to a class of medications called dual orexin receptor antagonists (DORAs). Quviviq is an effective insomnia treatment that works differently from other treatment options such as Ambien (zolpidem). It blocks chemical messengers in your brain that promote wakefulness.
But is it effective? In clinical studies, people reported sleeping better after 1 week of taking Quviviq every night, with improvements continuing to increase over 3 to 4 weeks. In these studies, they were able to fall asleep about 30 minutes faster after taking Quviviq for a month. They also stayed asleep about 20 to 30 minutes longer after falling asleep and slept a total of 35 to 45 minutes longer when compared to their baseline. The effectiveness of Quviviq is based on the dose. The 50 mg dose generally had a greater effect on sleep than the 25 mg dose. People also reported reduced daytime sleepiness when compared with placebo. This was seen after 1 week and continued to improve over time. The results reported after 1 month continued until month 3 in these studies.
Quviviq is effective in helping you get better sleep and it is generally well tolerated. While it is Schedule IV controlled substance, no evidence of physical dependence or withdrawal symptoms after stopping it over the course of a year. There was also no rebound insomnia when people came off of Quviviq. It should be noted that if you have a history of abuse or addiction to alcohol or other drugs, you may be at increased risk for abuse and addiction to this medication.
What is the mechanism of action for Quviviq in treating insomnia?
Quviviq is a dual orexin receptor antagonist (DORA) that works by blocking the actions of orexin, which is a chemical that signals your brain to stay awake. By turning down these overactive wake signals, this medication help you fall asleep sooner and stay asleep longer.
