How Does Viagra Works

Viagra (generic name is Sildenafil) is one of the most popular drugs around. A good number of men have used it and millions have sworn by its effectiveness. The term ‘Viagra’ is actually the brand name coined by Pfizer, the pharmaceutical company that first developed the innovative drug to treat erectile dysfunction, a condition characterized by the repeated inability to acquire and keep an erection for sexual contact.

This drug is highly effective in treating erectile dysfunction and is among the most commonly prescribed drugs by doctors. It generally works by blocking the chemical that makes blood leave the penis. It essentially makes more blood stay in the penis to improve and sustain erection.

Understanding how Viagra works requires an understanding on how erections develop. An erection happens when nerve signals are sent around the penis from the brain. During arousal, chemicals produced by the body are released because of the nerve signals, and they relax the penile muscles. When the muscles are relaxed, more blood can enter the penis, giving way to a full erection. However, you can lose the erection when another chemical called PDE5 (Phosphodiesterase type 5) causes the relaxation chemicals to break down. When that happens, the muscles in the penis constrict, so blood leaves.

How Viagra works

Basically, Viagra prevents PDE5 from doing its job. Viagra blocks that chemical so that (a) the chemicals that cause an erection can stay, and (2) the muscles in the penis do not constrict. The blood stays in the penis longer, and erection is maintained.

A lot of people believe that Viagra works even without sexual stimulation, but that is not true. The chemicals responsible for causing an erection should be released into the penis, and they are only released when aroused. Viagra does not make your body release these chemicals, but makes the chemicals stay longer in your penis. Therefore, you do not have to worry about getting spontaneous erections while you are taking Viagra.

A lot of people also wonder how long it will take before Viagra works. The answer to this actually varies. Clinical studies onĀ https://arbuthnotdrug.com reveal that Viagra can start working in as little as 14 minutes. However, based on experiences by most men, this little blue pill only starts working after about 30 minutes. Viagra’s effects last up to about 4 hours, but on average, there is a decrease in response after about 2 hours.
