How Viagra Works
Viagra functions by increasing blood flow to the penis during sexual arousal. It achieves this by inhibiting an enzyme called phosphodiesterase type 5 (PDE5) which results in the relaxation of blood vessels and improved blood flow. Here’s how it works:
- When a man is sexually stimulated, nitric oxide is released in the penis.
- Nitric oxide activates an enzyme that produces cyclic GMP.
- Cyclic GMP causes the blood vessels to relax and fill with blood, leading to an erection.
- Viagra helps prolong this state by preventing the breakdown of cyclic GMP.
