What is Viagra?
Viagra is a well-known medication used to treat erectile dysfunction (ED) in men. It contains sildenafil citrate, a drug that helps increase blood flow to the penis, enabling men to achieve and maintain an erection during sexual activity. Viagra is one of the most popular and widely prescribed ED treatments due to its effectiveness and reliability.
How Does Viagra Work?
Viagra works by inhibiting the enzyme phosphodiesterase type 5 (PDE5), which breaks down cyclic guanosine monophosphate (cGMP), a molecule that relaxes blood vessels and increases blood flow to the penis. By inhibiting PDE5, Viagra allows for the accumulation of cGMP, resulting in improved blood flow when sexually stimulated. This mechanism helps men get and sustain an erection. Viagra typically starts working 30 to 60 minutes after ingestion, with effects lasting up to 4 hours.
