Interesting article while searching for new sleep meds http://online.wsj.com/article/SB100...5392659897114.html#project=DREAMLANDDRUGS0621 A new sleep drug by Merck & Co. is expected to gain U.S. approval in the coming months, even as its main competitor is coming under growing scrutiny by regulators and doctors for sometimes-dangerous side effects. The new drug, known as suvorexant, will affect a different part of the brain than a generation of older medicines such as zolpidem, known as Ambien, which depresses brain activity. The hope is that suvorexant will cause fewer side effects than its older counterparts. Suvorexant/orexin has been waiting approval for along time now. They seem to be slow in approving this class of meds. I think they need to come up with a med that has reduced tolerance and can be used for long term insomnia which also help sleep initiation and maintenance.
