How does Viagra work?
Viagra is a medication used to treat erectile dysfunction. It works by increasing blood flow to the penis during sexual stimulation. Sildenafil citrate, the active ingredient, inhibits an enzyme called phosphodiesterase type 5 (PDE5), which normally breaks down cyclic guanosine monophosphate (cGMP). By inhibiting PDE5, Viagra allows cGMP to accumulate, leading to smoother muscle relaxation and increased blood flow, facilitating an erection [3].
