Cenforce pill is an effective generic drug for the treatment of impotence and benign prostatic hyperplasia (BPH) in men. Since sildenafil citrate is the main ingredient in this drug and Phosphodiesterase-5 (PDE5) inhibitor, the drug helps men achieve and maintain a longer erection by preventing the fall of cGMP, an important substance that regulates blood circulation. Intake of this drug accelerates blood flow to the penile region and thus, gives a strong erection to men for sexual intercourse. The drug usually starts working in 30-40 minutes.
