Mechanisrn of action of sildenafil

Sunday, March 23rd, 2008
Sildenafil is a competitive and reversible inhibitor of cGMP hydrolysis by the catalytic site of PDE5 . Sildenafil is an analog of cGMP , the PDE5 substrate , but PDE5 has - 1000-fold higher affinity for sildenafil than for cGMP. The purine ring of cGMP is mimicked by similar components in sildenafil , and this [...]

Sildenafil. Modulation of cellular cGMP level

Sunday, March 23rd, 2008
In all cells , the level of cGMP is primarily determined by the relative rates of cGMP synthesis by the GCs and its breakdown by PDEs. An imbal- ance between the synthesis ( e . g ., decreased release of nitric oxide due to penile nerve deterioration or endothelial cell damage ) and breakdown of [...]
