( Psoriasis patients who have been long-a...)New and unique treatment for Psoriasis patients,Health

Psoriasis patients who have been long-awaiting new options in treatment, now have fresh hope with the Food and Drug Administration's approval of the new drug, Amevive.

The treatments that are currently available for psoriasis range from ointments to ultraviolet therapy to other injected drugs that can broadly suppress// the immune system.

They found that 40 per cent of patients on the Amevive drug saw their psoriasis symptoms cut in half, as compared to about 10 percent of placebo-treated patients. A small number of patients even saw their lesions almost vanish, for at least a while. Though the duration for which the effect lasted was not known, a small subset of patients went seven months or longer before needing additional treatment. The FDA's Dr. Karen Weiss cautioned that though the drug has a much more selective effect, it is still too soon to say it is very selective and very safe.
