Suhagra 50 mg contains sildenafil citrate, which is the same active ingredient found in Viagra. Sildenafil citrate inhibits the enzyme PDE5, which is responsible for the degradation of cGMP (cyclic guanosine monophosphate). Increased levels of cGMP lead to smooth muscle relaxation in the blood vessels of the penis, allowing for increased blood flow and the development and maintenance of an erection.
