When did Dayvigo's patent expire?

What is lemSleep used for?
LemSleep is a medication prescribed to treat insomnia, specifically for individuals who have difficulty falling asleep and/or staying asleep [1]. It works by blocking the binding of orexins, which are chemicals in the brain that promote wakefulness [1].
How does lemSleep compare to other insomnia medications?
LemSleep belongs to a class of drugs known as orexin receptor antagonists [1]. This mechanism of action is different from older insomnia medications like benzodiazepines and non-benzodiazepines, which work by increasing the activity of GABA, a neurotransmitter that inhibits brain activity [1]. For example, Lunesta (esZopiclone) and Ambien (zolpidem) target GABA receptors [3]. LemSleep's dual orexin receptor antagonist action targets the wakefulness pathway directly [1].
What are the potential side effects of lemSleep?
Common side effects associated with lemSleep can include daytime drowsiness, headache, and somnolence [1]. It is important for patients to discuss any potential side effects with their healthcare provider [1].
