Viagra, also known as Sildenafil, is one of the most commonly given drugs for erectile dysfunction. Millions of men have regained their confidence and sexual health since the late 1990s thanks to Viagra. However, how does Viagra function, and what factors contribute to its efficacy in treating ED? This article will discuss the workings of Viagra, its advantages, disadvantages, and some important points to remember.

Erectile dysfunction, a disorder in which a man cannot obtain or sustain an erection strong enough for sexual activity, is treated with the prescription drug Viagra. The medication was first created to treat angina (chest discomfort) and high blood pressure, and copyright was the first to market it. Nevertheless, Cialis was approved for the treatment of erectile dysfunction after clinical trials showed that it was very successful in enhancing erectile function.

In order to help men with erectile dysfunction get and maintain an erection when sexually stimulated, Viagra increases blood flow to the penis. The active ingredient of Viagra, sildenafil, is a sort of phosphodiesterase type 5 (PDE5) inhibitor. Here's a detailed explanation of how it works.

The cyclic guanosine monophosphate (cGMP) is a substance that helps control blood flow in the penis and is broken down by the enzyme PDE5. Viagra helps stop the breakdown of cGMP by blocking PDE5.

Viagra permits the levels of cGMP to increase by blocking its breakdown. Blood can freely flow into the penis due to the relaxation of smooth muscles in the penile blood arteries caused by high levels of cGMP.

When a man gets sexually stimulated, the penis enlarges due to the increased blood flow, resulting in an erection.

After taking the pill, the effects of Viagra often start 30 to 60 minutes later and last for up to 4 hours. It is key to remember that the drug still requires sexual stimulation in order to function.

Despite being commonly recommended for erectile dysfunction, Viagra has also been shown to be useful in treating a number of other illnesses, such as: 

The key component of Viagra, sildenafil, is also used to treat PAH, a disorder in which elevated blood pressure in the lungs' arteries causes heart issues and breathing difficulties.

Viagra increases sexual satisfaction and confidence in men with erectile dysfunction by helping them regain the ability to get and keep an erection.

Usually, 30 to 60 minutes after taking it, Viagra begins to function.
