Viagra: All You Need to Know About the Pills for Men

Published On April 1, 2023

Updated on November 22, 2023

Viagra, commonly known as the ‘little Blue Pill’, is a well-known brand-name medication.

It was discovered by Pfizer in 1989, and the Food and Drug Administration (FDA) approved it for treating Erectile Dysfunction (ED) in 1998.

Since then, several men around the world have been able to overcome their erectile problems with Viagra.

The breakthrough of Viagra also paved the way for future Erectile Dysfunction treatments.

What is Viagra

Viagra is a small blue-colored tablet that includes the active salt Sildenafil Citrate. It is the first drug doctors prescribe for Erectile Dysfunction.

Erectile Dysfunction is a common sexual dysfunction that affects around 30 million people in the United States. It weakens a man’s ability to get and maintain an erection when aroused.

Viagra is taken orally, whenever needed, one hour before engaging in sexual activity.

What is Viagra used for

As mentioned, Viagra is used for treating Erectile Dysfunction (ED) in men or Assigned Males at Birth (AMAB).

Contrary to popular belief, Viagra does not increase your sex drive. You need to be in a state of sexual arousal to achieve an erection after taking Viagra.

Also, Viagra does not improve your performance in bed. It does not help you last longer in bed.

It only helps you achieve and keep an erection for a longer period in response to sexual stimulation. It may help you regain your erection quickly after ejaculation, meaning it reduces the refractory period.

Sildenafil (the active ingredient in Viagra) is also FDA-approved for treating Pulmonary Arterial Hypertension (PAH). It is sold under the brand name Revatio.

Did you know?

Pfizer first developed Sildenafil (Viagra) to combat Angina (chest pain). Sildenafil’s effect on erections was discovered by accident.
The discovery resulted in Viagra, the first medicine ever developed to treat Erectile Dysfunction.

How does Viagra work to treat ED

Viagra works by helping the blood vessels relax and increasing blood flow to the penis.

Sildenafil belongs to a class of Phosphodiesterase-5 (PDE5) inhibitors.

Erections occur when the nerve messages stimulate the penis during sexual arousal. The nerve impulses relax the muscles in the penile tissues, allowing better blood flow in the penis.

The blood increases pressure in the corpora cavernosa (soft tissue in the penis). It makes the penis expand and cause an erection.

Penile blood flow plays an essential role in the formation of an erection. An enzyme called cGMP is responsible for generating blood flow in the penis.

Erectile Dysfunction happens when another enzyme, PDE5, breaks down cGMP, restricting the blood flow necessary for erections.

PDE5 inhibitors like Sildenafil block the activity of PDE5 to prevent the breakdown of cGMP. They allow the muscles to relax and increase blood flow in the penis.

This enhanced blood circulation in the penile region helps men get and maintain a firm erection.

For a comprehensive understanding of factors that can affect erections, please refer to the following article – “What Causes a Man Not to Erect: Causes and Management?“.

How long does Viagra last

The effects of Viagra last for around 4 hours. The body quickly absorbs Viagra when taken orally.

The concentration of the medicine in the blood reaches its peak within 30 to 120 minutes of ingestion. You may start feeling the effects of Viagra within this duration.

After 4 hours of taking medicine, the effects start wearing off. It may be better to take Viagra one hour before you plan to have sex.

Other PDE5 inhibitors

As discussed earlier, Sildenafil is a PDE5 inhibitor. The FDA has also approved other PDE5 inhibitors that work the same way as Sildenafil.

These Erectile Dysfunction pills include:

Tadalafil (Cialis)
Vardenafil (Levitra)
Avanafil (Stendra)

Though these medicines act like Sildenafil, their effectiveness and duration of peak concentrations may vary.

If you desire a more spontaneous sexual experience, Cialis may be a better option. But, as the duration increases, so do the side effects of Cialis.

Levitra (Vardenafil) is a Viagra alternative for people with cardiovascular conditions. Compared to Viagra, it may be safer for heart patients.
