A phosphodiesterase-4 inhibitor, commonly referred to as a PDE4 inhibitor, is a drug used to block the degradative action of phosphodiesterase 4 (PDE4) on cyclic adenosine monophosphate (cAMP). It is a member of the larger family of PDE inhibitors .
Roflumilast, sold under the brand name Daxas among others, is a medication used for the treatment of chronic obstructive pulmonary disease, [4] plaque psoriasis, [5] seborrheic dermatitis, [6] and atopic dermatitis. [5] It acts as a selective, long-acting inhibitor of the enzyme phosphodiesterase-4 (PDE-4). [10] It has anti-inflammatory effects ...
Phosphodiesterase-5. A phosphodiesterase inhibitor is a drug that blocks one or more of the five subtypes of the enzyme phosphodiesterase (PDE), thereby preventing the inactivation of the intracellular second messengers, cyclic adenosine monophosphate (cAMP) and cyclic guanosine monophosphate (cGMP) by the respective PDE subtype(s).
Crisaborole is a phosphodiesterase-4 inhibitor, mainly acting on phosphodiesterase 4B (PDE4B), which causes inflammation. [6] Chemically, crisaborole is a phenoxybenzoxaborole . [ 6 ] Inhibition of PDE4B appears to suppress the release of tumor necrosis factor alpha (TNFα), interleukin-12 (IL-12), IL-23 and other cytokines , proteins believed ...
Apremilast, sold under the brand name Otezla among others, is a medication for the treatment of certain types of psoriasis and psoriatic arthritis. [4] The drug acts as a selective inhibitor of the enzyme phosphodiesterase 4 (PDE4). [4] It is taken by mouth. [4]

Inhibitors of PDE can prolong or enhance the effects of physiological processes mediated by cAMP or cGMP by inhibition of their degradation by PDE. [13] Sildenafil (Viagra) is an inhibitor of cGMP-specific phosphodiesterase type 5, which enhances the vasodilatory effects of cGMP in the corpus cavernosum and is used to treat erectile dysfunction.
