Merck’s insomnia drug moves a step closer to US approval

WASHINGTON, May 23: – Merck & Co’s experimental insomnia drug moved a step closer to U.S. Approval on Wednesday after a panel of medical experts said it is effective and safe at lower doses. The advisory panel was convened to help the U.S. Food and Drug Administration decide whether to approve the drug, suvorexant, which would be the first in a new class of sedatives that block chemicals in the brain called orexins that help keep people awake. The drugs are designed to help people fall asleep and stay asleep. (AGENCIES)
