Viagra works by relaxing the muscles in the arteries leading to the penis, thereby improving blood flow. This, in turn, aids in achieving an erection.
To understand Viagra’s working mechanism, it is essential to understand the phenomenon of erections and ED first.

During sexual arousal, the nerve impulses from the brain begin to stimulate the penis. The muscles of the corpora cavernosa relax in response to signals from the brain and local nerves.
They allow the blood to enter and fill the voids. The blood generates pressure in the corpora cavernosa, causing the penis to swell and produce an erection.
How does Erectile Dysfunction happen
The enzyme Phosphodiesterase type 5 (PDE5) stops erectile function by preventing the blood flow in the penis. It also affects the nerve messengers involved in sexual stimulation.
Thus, it leads to Erectile Dysfunction by interrupting the erectile process. Conditions such as Diabetes, Hypertension, Obesity, and heart disease can reduce the blood supply to the penis. Thus, these conditions are some of the leading causes of ED.
How does Viagra work
Sildenafil (Viagra) is a member of the class of medicines known as PDE5 inhibitors. These medicines function by blocking the enzyme PDE5, which inhibits erectile function.
Medicines such as Viagra inhibit PDE5 and relax the penis’s muscles and blood arteries. This allows more blood to reach the penis.
The nerves stimulating the penis during sexual arousal increase blood pressure, which aids in erecting the penis. Thus, Viagra aids in achieving an erection.
How fast does Viagra work
Viagra generally works shortly after you take a tablet. Usually, it takes effect within an hour.
For some, it may work as early as 30 minutes after a dose. But in rare cases, it could take 4 hours to produce results.
How long does Viagra last
Viagra has a half-life of around 4 hours. Depending on your dose, its effects may last 4 to 6 hours.
Viagra typically works best an hour after you take a dose. After that, the body slowly starts eliminating the contents of the drug.
Although Viagra can remain in your body for over four hours, your erection will not last that long.
However, people with penile deformities, sickle cell anemia, or leukemia may experience prolonged erections.
