Fildena 100  tablets contain sildenafil citrate. Sildenafil citrate is a salt that is part of the cyclical ladder of GMP in the body and is a means of s*xual transmission by directing nitric oxide.Fildena (sildenafil citrate) tablets are prone to aggregation of PDE type 5 inhibitors.The extended measurement of PDE5 in the body messes up the cyclic GMP and thus one may not be able to lift the p*nis during s*xual intercourse due to erectile dysfunction.Since Fildena or Sildenafil Citrate tablets direct the measurement of PDE5 protein, then they expand cyclic GMP which is a s*xual carrier that is provided due to s*xual enhancements when nitric oxide is secreted by the brain.
