5-Methoxypsoralen, a naturally occurring linear furocoumarin, has been successfully used in combination with ultraviolet (UV) A irradiation [psoralen plus UV (PUVA)] to manage psoriasis and vitiligo. In patients and volunteers, PUVA 5-methoxypsoralen causes a dose-related increase in cutaneous
Photochemotherapy is very effective for the treatment of skin diseases such as psoriasis, as well as for the prophylactic 'hardening' therapy of patients suffering from polymorphic light eruption. The photosensitizers most widely used for oral photochemotherapy are the furocoumarins
Photosensitizers were first used to treat psoriasis 15 years ago when the phototoxic reaction of psoralens and UVA was found to induce remissions of the disease. The effect of this reaction on DNA, particularly the formation of cross-links, was thought to be the decisive event. Strong cross-linking
