The FDA has recently approved a new sleep medication – Suvorexant – which works as a orexin receptor blocker. What is orexin? This is a key switch that keeps us awake, and is low in people with narcolepsy – so temporarily blocking it will put you to sleep. Because orexin is “the master switch” for sleep and wake – your sleep on this medication may be more natural than any other sleep aid on the market. The only issues so far – it may work too long; into the next day – but hopefully this is dose dependent.
