ildenafil Citrate, the active ingredient in Aurogra 100 mg, works by inhibiting the enzyme PDE5. This enzyme breaks down cyclic guanosine monophosphate (cGMP), which is responsible for relaxing smooth muscle in the blood vessels of the penis.By inhibiting PDE5, Aurogra 100 mg increases the levels of cGMP, leading to enhanced blood flow to the penis when sexually aroused, resulting in an erection.
