Treatment# Topical therapy
Local therapy alone may bring about adequate improvement in mild or moderate cases of psoriasis. Local therapy is also generally used in addition whenever phototherapy or systemic therapy is given.
# Quality of life
The goal of short- and long-term treatment of psoriasis should be a marked,measurable improvement of the quality of life.
Topical corticoids of strength classes II and III remain the medications most commonly used to treat psoriasis. They have a favorable risk/benefit profile when properly used and are also very effective against itching,from which about two-thirds of patients suffer. Topical corticoids should not be used over long periods (i.e.,for more than 6 weeks continuously) without interruption in order not to produce typical corticoid side effects such as skin atrophy.
Vitamin D3 analogues (cacipotriol,tacalcitol) have come into wide use in recent years. These,too,have a favorable risk/benefit profile,though they are somewhat less effective than the corticoids. Side effects such as local irritation at the beginning of treatment,are rare. A combined preparation consisting of the vitamin D3 analogue calcipotriol together with a corticoid of intermediate strength,which was studied in a controlled trial over a study interval of an entire year,is very effective and is often used as first-line treatment. The medication can be applied once daily,and its safety,tolerability,and effectiveness are high ). Anthralin is still used with good results,mainly in the inpatient setting,but it is impractical for use by outpatients. This drug,too,causes local irritation ("anthralin dermatitis"). Tars have been shown to have an unfavorable risk-benefit profile and are no longer used in the topical treatment of psoriasis ). Other skin-care products can be used to good effect alongside the specifically antipsoriatic medications,or during treatment intervals.","department":"
