By inhibiting PDE5, sildenafil increases the levels of cGMP, leading to enhanced blood flow into the penis and facilitating the achievement and maintenance of an erection in response to sexual stimulation. Viagra works by inhibiting the enzyme phosphodiesterase type 5 (PDE5), which breaks down cyclic guanosine monophosphate (cGMP), a molecule that promotes relaxation of the smooth muscle in the corpus cavernosum of the penis.
