What is the blue pill? Well, they are pretty popular medications consumed by many males.

Viagra, often known as “little blue pills,” is the first medication for treating Erectile Dysfunction (ED).

Erectile Dysfunction is known as the incapability of males to achieve and maintain an erection.

Blue pills for men contain Sildenafil, which is the first Phosphodiesterase 5 (PDE5) inhibitor authorized by the Food and Drug Administration (FDA) to treat ED.

This PDE5 enzyme inhibition enhances blood circulation to the penile area, resulting in an erection.

PDE5 inhibitors, such as the blue pill, are therefore beneficial in treating ED or impotence.

Let’s delve through the article to discover what is the blue pill and what these tablets do.

What is the blue pill?

Pfizer initially developed Sildenafil for the treatment of Hypertension and Angina Pectoris.

During heart patients’ clinical testing, researchers discovered that the medication was more effective at inducing erections than at treating Angina.

Therefore, the Food and Drug Administration authorized Sildenafil to treat Erectile Dysfunction in 1998.

Pfizer launched a generic version of Viagra, or the blue pill, to the marketplace in 2017.

Generic Viagra also contains the same salt, Sildenafil, and is less expensive than the brand-name medicine.

As the Viagra patent expired in 2020, other manufacturers began making generic Sildenafil medications globally.

Sildenafil is the active element in generic medicines like Cenforce, Fildena, and Kamagra.

I hope you got the answer to what is the blue pill. Now let us look at what this pill does.

By now, you know that blue pills treat impotence or Erectile Dysfunction in men.

But how?

Well, Sildenafil in the blue pill is a PDE5 inhibitor.

By inhibiting PDE5, cyclic Guanosine Monophosphate (cGMP) breakdown is prevented.

When cGMP levels rise, relaxation and vasodilation of penile smooth muscles occur. 

This relaxation and dilation increase blood flow to the male sexual organs.

Because of this, a male can attain and sustain an erection.

Nevertheless, sexual stimulation is required for this blue pill to work.

Are the blue pills for men effective?

Now that you know what is the blue pill and how it works, we can say that these pills are pretty effective.

As was said earlier, Erectile Dysfunction is caused due to insufficient blood flow to the penis.

Blue pills aid the same by boosting the blood flow to the penile region.

Thus, causing an erection when sexual stimulation happens and effectively treating ED in men.

However, taking this medicine between 30 minutes to 4 hours before getting intimate to get the results is vital.
