Viagra

Since its inception in 1998, Viagra has been a divine gift for millions of men who had lost their sexual life due to erectile dysfunction. Viagra has Sildenafil Citrate as an active ingredient. The effect of Viagra could be noticed with in 30 minutes after consumption and lasts for 4 hours and it works by increasing blood flow to the penis.

Viagra promotes erections by relaxing the smooth muscle of the blood vessels thus increasing blood flow in the penis in response to sexual stimulation. It does this by specifically blocking a particular enzyme (protein that assists chemical reactions) called phosphodiesterase type 5 (PDE 5). This is the enzyme that normally breaks down chemicals causing the erectile response. Therefore, by blocking the breakdown of erectile chemicals, the drug promotes a harder and more prolonged erection.
