Psoriasis Treatment: Topicals
Since psoriasis mainly affects the skin, topical treatments are very useful because they are relatively safe, quite effective, and can be applied directly to the disease. They take the form of lotions, foams, creams, ointments, gels, and shampoos. They include topical steroids, tar preparations, and calcium- modulating drugs. The precise drug used and the form in which it is delivered depends on the areas involved. In widespread disease in patients with more than 10% of the body surface involved, it may not be practical to use topical medication alone.
