Introduction to Viagra

Viagra, also known by its generic name sildenafil, is a medication primarily used to treat erectile dysfunction (ED) in men. It helps by increasing blood flow to the penis, thereby facilitating an erection when combined with sexual stimulation.

How Does Viagra Work for Men?

Viagra belongs to a class of drugs called phosphodiesterase type 5 (PDE5) inhibitors. It works by blocking the enzyme PDE5, which is responsible for the breakdown of cGMP. This substance relaxes smooth muscles and widens blood vessels. This process allows for increased blood flow into the penile tissues, helping to produce an erection during sexual arousal.
