(Reuters) - U.S. drug reviewers said a Jazz Pharmaceuticals Inc medicine helped patients with the pain disorder fibromyalgia, sending shares up 14 percent Wednesday on hopes an approval could sharply boost the company's sales.
Food and Drug Administration staff said the drug, sodium oxybate or JZP-6, was effective. But they also questioned if the company's proposed safeguards would adequately prevent improper use. The medicine contains an ingredient notoriously abused as a "date rape" drug.
