🔬 How This Medicine Works (Pharmacology)
Pharmacokinetics
How It Works
Methoxsalen is a psoralen that intercalates between DNA base pairs. Upon exposure to UVA light, it forms covalent cross-links with pyrimidine bases, leading to DNA damage and inhibition of DNA synthesis. This slows down the rapid proliferation of skin cells, which is beneficial in psoriasis and other hyperproliferative skin conditions. In vitiligo, it stimulates melanocyte activity and migration, leading to repigmentation.
