Psoriasis can be controlled and stabilized by medication and physical therapy to reduce the symptoms of skin lesions and itching, but it is difficult to be cured completely, and there are individual differences in the treatment effect, so there is no so-called “best” treatment method. 1. Topical drugs: corresponding treatment should be carried out according to the condition. Ordinary-type psoriasis can be treated with medium- or strong-acting glucocorticosteroids, such as mometasone and triamcinolone acetonide, etc.; quiescent plaque-type psoriasis can be treated with drugs such as caspofloxacin, tacalcitol, tazarotene, etc.; tacrolimus, pimecrolimus, etc. can be used for treating psoriasis in the face, armpit and other parts of the body; 2. Systemic drugs: methotrexate, cyclosporine, vinblastine and other systemic drugs are often used to treat psoriasis with a wide area of rash and in the developmental stage; in recent years, biologics such as etanercept, infliximab and other biologics have made great progress in the treatment of psoriasis. 3. Physical therapy: photochemotherapy, narrow-spectrum UVB phototherapy, hot spring bath, sunbathing and other physical therapy can be used in the treatment of psoriasis. It is suggested that patients with psoriasis should seek medical treatment in time, standardize the treatment under the guidance of doctors, and avoid private medication to avoid delaying the condition.
