Genenric Dovonex scalp solution for psoriasis coming

According to Reuters:

Hi-Tech Pharmacal Co. Inc. said the U.S. Food and Drug Administration has granted it tentative approval for the generic version of Warner Chilcott Ltd.'s treatment for psoriasis of the scalp.

Hi-Tech reported that Warner Chilcott's patent for Dovonex scalp solution (calcipotriene) is set to expire on Dec. 29, 2007, after which the generic would become available. So it looks like barring a legal dispute over the patent expiration date, there may be a less expensive calcipotriene scalp treatment by New Year's.
