How Viagra Works
Viagra functions by inhibiting the enzyme phosphodiesterase type 5 (PDE5). This action leads to the relaxation of blood vessels in the penis, allowing increased blood flow and facilitating an erection during sexual stimulation. Here are the key processes involved:
- Sexual arousal triggers the release of nitric oxide in the corpus cavernosum.
- Nitric oxide stimulates guanylate cyclase, increasing levels of cyclic guanosine monophosphate (cGMP).
- cGMP causes smooth muscle relaxation and increased blood flow to the penis.
- Viagra inhibits PDE5, prolonging the effects of cGMP and assisting in maintaining the erection.
