ORIGINAL RESEARCH-BASIC SCIENCE: A Nitric Oxide‐Releasing PDE5 Inhibitor Relaxes Human Corpus Cavernosum in the Absence of Endogenous Nitric Oxide

These results show that the potency of NCX‐911 was maintained unlike sildenafil in the absence of endogenous NO confirming the potential use of NO‐releasing PDE5 inhibitors in NO‐deficient conditions.
