Free radicals are responsible for the symptoms experienced in erythropoietic protoporphyria.<\/li>\n<\/ul>\n<h2><span class=\"ez-toc-section\" id=\"%C2%BFQue-afecciones-de-la-piel-responden-a-la-afamelanotida\"><\/span>What skin conditions respond to afamelanotide?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Afamelanotide is registered to treat erythropoietic protoporphyria.

One to 20 minutes after sun exposure, patients experience burning pain in <span class=\"term\" data-term-id=\"311\">exposed skin<\/span>, usually hands and face, followed by swelling and redness that lasts for several days. Fear of this pain can have a major effect on quality of life, including job and recreational opportunities.<\/p>\n<p>Afamelanotide has been shown through phase III studies to decrease <span class=\"term\" data-term-id=\"1690\">phototoxic<\/span> Reactions and recovery time in patients with erythropoietic protoporphyria. Afamelanotide was first used for the treatment of erythropoietic protoporphyria in Italy and Switzerland in 2007. It reduced pain and allowed almost all patients to be outdoors for longer periods than before.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"Urticaria-solar\"><\/span>Solar urticaria<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>Solar urticaria is a rare form of <span class=\"term\" data-term-id=\"319\">chronic<\/span> physical or <span class=\"term\" data-term-id=\"1647\">inducible<\/span> urticaria characterized by itching, <span class=\"term\" data-term-id=\"302\">bump<\/span> and explode within minutes of exposure to sunlight. The spectrum of action (the part of the electromagnetic spectrum that causes symptoms) is variable, but most often involves long-wavelength UVA and visible light. The use of afamelanotide has been shown under experimental conditions to reduce the formation of scars secondary to increased melanization.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"Vitiligo\"><\/span>Vitiligo<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>Vitiligo is a disorder characterized by white patches on the skin due to the selective loss of <span class=\"term\" data-term-id=\"846\">epidermal<\/span> <span class=\"term\" data-term-id=\"181\">melanocytes<\/span>.
