Cialis and Viagra are among the most successful ED pills.
They are brand-name medications used to reverse the symptoms of impotence.
Erectile Dysfunction (ED), or impotence, is the inability to get or maintain a firm erection.
ED may lead to psychological trauma, low self-esteem, and frustration if left untreated.
Also, ED may indicate underlying health disorders such as heart issues, diabetes, depression, etc.
So, it is essential to get the appropriate treatment for Erectile Dysfunction.
Fortunately, there are various ED treatments available, including prescription-based ED pills.
Viagra reigned supremacy for 5 years until Cialis entered the game.
According to research, there was an increase in the sales of ED pills in 2020. This increase was driven by an 85% rise in the sale of Tadalafil.
Both medicines are equally effective in treating Erectile Dysfunction.
However, they have some key differences that make them unique in their way.
In this article on Cialis vs Viagra, we have elaborated on all the differences that can affect your decision.
Cialis vs Viagra: Key differences
Cialis and Viagra both belong to a category of Phosphodiesterase Type 5 (PDE5) inhibitors.
Since they belong to the same category, their mechanisms of action for treating ED are identical.
Viagra and Cialis both inhibit the activity of PDE5 enzymes.
PDE5 enzymes are responsible for breaking down the cyclic Guanosine Monophosphate (cGMP) levels.
cGMP is a chemical that is synthesized by Nitric oxide during sexual stimulation. It is important for the dilation of penile blood vessels.
Inhibition of PDE5 enzymes by ED pills restores cGMP levels. This leads to the dilation of penile blood vessels.
Thus, boosting blood flow to the penis, resulting in a long-lasting erection.
Although they have the same working, there are some notable differences between Viagra and Cialis.

Cialis and Viagra work similarly but differ on the grounds of their composition.
The main active ingredient in Cialis is Tadalafil, while the main salt in Viagra is Sildenafil.
Tadalafil got its FDA approval on November 21, 2003.
It was the third PDE5 inhibitor that entered the market.
Eli Lilly produced and marketed Tadalafil under the brand name Cialis.
On the other hand, Sildenafil got its FDA approval in 1998.
It was the first PDE 5 inhibitor that was approved to treat Erectile Dysfunction.
