Cenforce 100 mg[https://genericcures.us/product/cenforce-100-mg-sildenafil-citrate/] works by inhibiting the enzyme phosphodiesterase type 5 (PDE5), which is responsible for breaking down cGMP, a substance that relaxes the smooth muscles in the penis and allows for increased blood flow. By inhibiting PDE5, Cenforce 100 mg helps to maintain the levels of cGMP in the penis, resulting in a stronger, more sustained erection.
