Sildenafil citrate in Suhagra 100 mg works by inhibiting the action of PDE5, an enzyme that breaks down cyclic guanosine monophosphate (cGMP). During sexual arousal, nitric oxide is released in the erectile tissue of the penis, leading to increased levels of cGMP. cGMP relaxes the smooth muscles in the penile blood vessels, allowing them to dilate and increase blood flow to the penis. By inhibiting PDE5, sildenafil helps maintain higher levels of cGMP, promoting sustained relaxation of the smooth muscles and improved blood flow.
