New type of med may eliminate grogginess, other side effects, study suggests.

A new class of sleep medications appears to help people fall asleep without causing grogginess the next day, researchers say.

These new medications — known as dual orexin receptor antagonists (DORA) — target a more specific region of the brain than popular sleep drugs such as Ambien and Lunesta, promoting sleep without affecting learning and memory (also called “cognition”), according to the new research.

“We’ve shown that these compounds improve sleep ...

British study shows pattern between children receiving the 2009 swine flu vaccine, Pandemrix, and developing narcolepsy.
