Abstract:
Three agents have recently been approved by the Food and Drug Administration for the treatment of chronic plaque psoriasis: alefacept, efalizumab, and etanercept. The field of dermatology has now entered a new era, joining other disciplines of medicine that have been using biologic agents for decades.
