1, corticosteroid drugs These drugs can be taken orally, can also be used externally or local irradiation, for the treatment of vitiligo disease have a certain effect. This is because corticosteroid preparations can improve the stress capacity of local tissues to harmful stimuli, block the release of cytotoxic substances, improve microcirculation, promote melanocyte proliferation and melanin synthesis and other effects, so as to inhibit the abnormal immune inflammatory reaction at the vitiligo lesions, stop the progressive destruction of melanocytes and enhance their function, so that the pigmentation of the white spots regeneration.
2, anti peroxidant drugs Vitiligo occurs mainly because the human body melanin reduction is caused, so patients to avoid damage to melanocytes, and topical anti peroxidants have inhibited the production of epidermal peroxide, eliminate excessive accumulation of epidermal hydrogen peroxide, reduce the oxygen free radical damage to melanocytes and other effects, so that melanocytes restore normal function, the white spot re-colored.
3, the complementary osteopontin class of drugs This class of drugs is the earliest application to treat vitiligo disease, but also has been used in the treatment of vitiligo drugs. It can make skin pigmentation tyrosinase is the key enzyme of human melanin biosynthesis. By increasing the activity of tyrosinase in human body, tonic promotes the synthesis of melanin and restores the skin color at the white spots. To achieve the purpose of treating vitiligo.
4, photosensitizer class drugs As vitiligo patients are more sensitive to light, so to avoid ultraviolet light damage to the skin, and photosensitizer can enhance the skin’s photosensitive reaction to ultraviolet light, has the ability to reduce the number of Langerhans cells in vitiligo lesions, regulate the immune response of local tissues, inhibit the progressive destruction of melanocytes by autoantibodies, promote melanocyte DNA replication, improve tyrosinase activity, activate It also promotes melanocyte DNA replication, increases tyrosinase activity, activates the proliferation of non-functional melanocytes in the root sheath of the hair follicle, and promotes their differentiation and maturation and migration to the epidermis to regenerate pigmentation at the white spots.
When using medication, it is best to go to a specialized hospital to receive professional medical consultation and follow the doctor’s instructions. Do not abuse without diagnosis to avoid aggravation of the disease.
