Medications used in psoriasis
Although natural remedies show significant improvement in a large number of cases and that they are used almost always with any other treatment, they are not enough in advanced cases and further medical therapy is needed. Common medical therapy used includes:
1) PUVA therapy:
PUVA stands for Psoralen therapy with ultraviolet B radiation. Psoralen is a chemical substance ingested by the patient before ultraviolet therapy to concentrate ultraviolet radiation at the site of skin lesions. Ultraviolet therapy is considered as one of the most effective methods of controlling skin manifestations. It induces remission of the disease through acting on the cells that directly cause the mechanism of it. It does come with side effects though and excessive exposure to ultraviolet radiation especially in people with fair skin increases the risk of developing skin cancer. Narrow band ultraviolet radiation can also be used without psoralen.
