WASHINGTON (AP) - A Pfizer Inc. drug won expanded federal approval Thursday as the first treatment for fibromyalgia, a mysterious syndrome marked by muscle pain and fatigue.
The Food and Drug Administration action means Lyrica becomes the first drug that can be marketed specifically as a treatment for adults with fibromyalgia. Patients currently make so-called "off label" use of pain medications, antidepressants, muscle relaxants and sleep aids to treat the condition. Exercise and applying heat also can help.
Fibromyalgia typically affects women, striking them with long-lasting or chronic pain, as well as muscle stiffness and tenderness, according to the FDA. An estimated 3 million to 6 million people in the United States are affected each year.
