- Inhibition of Phosphodiesterase Type 5 (PDE5):
- Sildenafil citrate, the active component of Fildena, inhibits the enzyme phosphodiesterase type 5 (PDE5). This enzyme is responsible for the breakdown of cyclic guanosine monophosphate (cGMP), a molecule that promotes relaxation of smooth muscle tissue.
- Increase in cGMP Levels:
- By inhibiting PDE5, Buy cheap Viagra online leads to increased levels of cGMP. This results in the relaxation of the smooth muscle cells in the blood vessels of the penis.
- Enhanced Blood Flow:
- The relaxation of these blood vessels allows for increased blood flow into the penile tissue when a man is sexually stimulated. This blood engorgement in the corpus cavernosum leads to an erection.
