Cenforce 200mg or Sildenafil tablets work very effectively. First of all, it is essential to know that Sildenafil Citrate 200mg belongs to the group of PDE-5 inhibitors. All drugs, including Sildenafil, belong to this group and can quickly reduce the level of the PDE-5 enzyme in men.

Therefore, when the body has a higher level of cGMP, more blood reaches the penile region.
