Sildenafil is a common medication used to stimulate erections in men with erectile dysfunction (ED) and treat certain heart conditions. Many factors can influence how long Viagra takes to start working. In general, Viagra takes about 30 minutes to produce noticeable effects. But your diet, your overall health, the medications you’re taking, underlying conditions, and much more can all affect the amount of time Viagra takes to work in your body and how long it lasts. An erection happens when nerves in your penis are stimulated. Then, muscles around two cylinder-shaped chambers of spongy material along your penis, known as the corpus cavernosa, relax and allow blood to flow in, causing an erection. With ED, your nerves don’t communicate properly with your brain and blood doesn’t flow properly into the corpus cavernosa. Taking Viagra relaxes the walls of your blood vessels and lets blood flow more easily into the parts of your penis that cause an erection. You’ll still need to feel sexually aroused to get an erection. metformin combo Sildenafil is a medicine used to treat erectile dysfunction.

An erection is produced via a complex chain of events, involving signals from the nervous system and the release of chemical messengers within the tissues of the penis. One of the messengers released when you are aroused is called cyclic GMP. Cyclic GMP relaxes and widens the blood vessels in the penis, allowing more blood to enter. Cyclic GMP is normally broken down by an enzyme in the body called phosphodiesterase type 5 (PDE5). Sildenafil is a type of medicine called a PDE5 inhibitor. It works by stopping this enzyme from breaking down the cyclic GMP. This allows the blood vessels in the penis to stay dilated for longer, which improves blood flow to the penis and helps produce and maintain an erection.
