Mechanism of action

PDE4 inhibition increases intracellular cAMP levels in immune and inflammatory cells, suppressing the production of pro-inflammatory cytokines such as TNF-α and IL-23. This mechanism reduces skin inflammation and is particularly effective in atopic dermatitis and other inflammatory skin conditions where PDE4 plays a key pathogenic role.
