STAMFORD, Conn. — An insomnia drug made by Purdue Pharma "significantly" reduced the time it took patients to return to sleep after they'd woke up in the middle of the night, according to a new study.
The placebo-controlled study, published in the journal Sleep, tested the drug Intermezzo (zolpidem tartrate) sublingual tablets on 295 adults with primary insomnia and difficulty returning to sleep after waking up in the middle of the night. Purdue said Intermezzo was the only drug approved by the Food and Drug Administration for treating such patients.
