Questcor dropped 29 percent to $21.40 at 7:37 a.m. New York time, in trading before the market open, after earlier touching as low as $20.75. The Anaheim, California-based company has fallen 28 percent this year before today.

Acthar, a treatment for multiple sclerosis and infant seizures. The drug accounts for most of Questcor’s sales. Marko Kozul, an analyst at Leerink Swann in San Francisco, downgraded the stock to market perform today.
