As mentioned, Cialis and Tadalafil treat Erectile Dysfunction in men. Tadalafil is the active component present in Cialis. However, Tadalafil is also available as a generic alternative to Cialis.

Eli Lilly, a pharmaceutical corporation, manufactured the well-known Erectile Dysfunction pill Cialis in 2003.

In 2008, the FDA approved Cialis as a treatment for Erectile Dysfunction.

The generic version of Cialis, Tadalafil, was created by pharmaceutical companies after the patent on the original drug expired in 2017.

As a result, Tadalafil, a generic form of Cialis, came into the market. This is significantly less expensive and just as effective for treating Erectile Dysfunction.

How do Cialis and Tadalafil work

Tadalafil belongs to the group of medicines called Phosphodiesterase Type 5 (abbreviated as PDE 5) inhibitors.

The medicine helps in inhibiting PDE5 enzymes which are responsible for breaking cyclic Guanosine Monophosphate (cGMP) levels.

Hence, the PDE5 inhibitors work by increasing the cGMP levels in the body.

Increased cGMP levels boost the penile blood flow, which is necessary for maintaining an erection. Thus, it helps a man get and keep the desired erection for a fulfilling sexual experience.

This medicine may start working as early as 16 minutes. It’s only effective when the person is sexually stimulated.

Cialis, which contains Tadalafil as its active ingredient, works in the same way. The effects of Cialis and generic Tadalafil pills may slightly vary due to the presence of inactive ingredients
