Özet

Purpose: Conflicting information exists regarding the long-term efficacy of phosphodiesterase-5 (PDE5) inhibitor therapy for erectile dysfunction, particularly in regard to whether therapeutic resistance occurs. We investigated the erectile response, and cavernous PDE5 expression and activity after continuous long-term administration of sildenafil at verified therapeutic plasma concentrations, applying an in vivo rat model of age related erectile dysfunction.
