Sildenafil citrate, the active ingredient in Suhagra 50 mg, works by inhibiting the enzyme phosphodiesterase type 5. This inhibition leads to increased levels of cyclic guanosine monophosphate (cGMP), a chemical that relaxes the smooth muscles in the blood vessels of the penis. This relaxation allows for improved blood flow to the penis, facilitating the ability to achieve and maintain an erection when sexually aroused.
