The mechanism of action of Viagra involves the enhancement of nitric oxide (NO) effects in the corpus cavernosum of the penis. Viagra works by inhibiting the enzyme phosphodiesterase type 5 (PDE5), which results in an increase in the levels of cyclic guanosine monophosphate (cGMP). Elevated levels of cGMP lead to smooth muscle relaxation and increased blood flow to the penis, facilitating the erection process.
