Fildena 100mg tablets contain sildenafil citrate. Sildenafil Citrate is a salt that forms the GMP cyclic scale 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.Extensive measurement of PDE5 in the body messes up the cyclic GMP and therefore you 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 the PDE5 protein, they expand the cyclic GMP, which is a sexual carrier that is provided due to s*xual enhancements when nitric oxide is secreted from the brain.
