So, um I I believe the mechanism with with Viagra is not the end production of nitric oxide, but it's a PDE5 inhibitor, right? And so actually nitric oxide typically bonds to um cyclic GMP and then that well that creates cyclic cgmp and the cgmp molecules um then have all these signaling effects and then that gets broken down by phosphodieststerase. So then Viagra inhibits phosphodiesttor.
