Danafil 25 mg Tablet
Danafil (Sildenafil Citrate) is a selective inhibitor of cyclic Guanosine Monophosphate (cGMP)-specific phosphodiesterase type 5 (PDE5) for treatment of erectile dysfunction. Danafil (Sildenafil Citrate) enhances the effect of nitric oxide (NO) by inhibiting phosphodiesterase type 5 (PDE5), which is responsible for degradation of cGMP in the corpus cavernosum that results in smooth muscle relaxation and inflow of blood to the corpus cavernosum.
Danafil is indicated for the treatment of erectile dysfunction.
