Roflumilast is a highly selective phosphodiesterase-4 (PDE4) inhibitor.[A251385] PDE4 is a major cyclic-3',5′-adenosinemonophosphate (cyclic AMP, cAMP)-metabolizing enzyme [L37564] expressed on nearly all immune and pro-inflammatory cells, in addition to structural cells like those of the smooth muscle or epithelium.[A251385] The resultant increase in intracellular cAMP induced by roflumilast's inhibition of PDE4 is thought to mediate its disease-modifying effects, although its precise mechanism of action has yet to be elucidated.[L37564,A251385] The oral formulation of roflumilast is indicated to manage chronic obstructive pulmonary disease.[L46546] It was first approved by the EMA in July 2010, and by the FDA in January 2018.[L37564] Roflumilast topical cream is indicated to treat plaque psoriasis. The cream formulation was first approved by the FDA in July 2022 [L42580] and by Health Canada in April 2023.[L46541] On December 15, 2023, the FDA approved a new topical foam formulation of roflumilast for the treatment of seborrheic dermatitis in patients aged 9 years and older.[L49281]
