Psoriasis is a chronic disease that is usually difficult to disappear suddenly, but symptoms can be improved by topical medication, oral medication, and physical therapy. 1. Topical drug treatment: Calcium-modulated phosphatase inhibitors (such as tacrolimus cream, pimecrolimus ointment), glucocorticoid creams (such as hydrocortisone butyrate, hallucinogen), vitamin D₃ derivatives (such as calcipotriol, tacalcitol), and coal tar can be given to apply treatment. 2. Oral medication: Oral medication such as vitamin A acid such as Avitamin A and immunosuppressants such as methotrexate can be given. 3. Physical therapy: Physical methods such as medicated baths and phototherapy can also be used to treat psoriasis. If you suffer from psoriasis, it is recommended to go to the hospital in time to receive professional diagnosis and treatment, and the drugs should be used according to the doctor’s instructions.
