Mechanism of action

As a topical formulation, methotrexate penetrates skin tissue to inhibit dihydrofolate reductase, disrupting purine and pyrimidine synthesis. This reduces proliferation of keratinocytes and immune cells in the dermis and epidermis. The anti-inflammatory and immunosuppressive properties make it effective for inflammatory and proliferative skin conditions.
