Study Picks Older Psoriasis Treatment
Posted on: Wednesday, 19 July 2006, 15:01 CDT
A British study says an older treatment using ultraviolet A light works better in treating psoriasis than a more convenient one using ultraviolet B light.
The study done at King's College in London said PUVA works better in clearing psoriasis outbreaks. PUVA uses the oral drug Psoralen which makes the skin much more light sensitive, reports WebMD.
But the report said it takes about 16 to 19 PUVA treatments to bring about remission.
Dermatologists had hoped the other treatment - using narrowband ultraviolet B (NB-UVB) light - would fight psoriasis as well as PUVA.
Compared with NB-UVB, PUVA achieves clearance in more patients, with fewer treatment sessions, and results in longer remissions, said the study's leader Sami S. Yones. The study said for most patients, remission after PUVA lasted eight months, compared to NB-UVB's four months.
The findings appear in the July issue of Archives of Dermatology.
