How OXSORALEN-ULTRA Works

When exposed to UVA light, the drug forms covalent bonds and crosslinks with DNA, which effectively stops DNA synthesis and prevents cell division. This action helps slow down the turnover of diseased cells and may also stimulate an immune response against malignant T-cells.
