Cialis, commonly known by the generic name Tadalafil, is one of the most popular medicines used for treating Erectile Dysfunction in men or Assigned Males at Birth (AMAB). While Cialis is beneficial for many people, there are instances where patients report that it does not work as expected.
Several physical and psychological factors, such as Diabetes and Anxiety, could be the reason behind this. Understanding the exact causes of why Cialis is not working can help people address the problem properly.
This article will explore the several causes why Cialis may not be effective for some people. We’ll also offer suggestions on what to do if you encounter this problem.
Understanding How Cialis Works
Cialis is a Phosphodiesterase type 5 (PDE5) inhibitor that works by inhibiting the PDE5 enzyme.
In normal conditions, sexual stimulation leads to the production of Nitric Oxide (NO) in the penis. This NO increases the production of Cyclic Guanosine Monophosphate (cGMP).
Thie compound cGMP is essential for relaxing the smooth muscles of blood arteries, enabling more blood flow to the penis, resulting in an erection.
However, the PDE5 enzyme degrades cGMP, hindering the onset of an erection. Cialis inhibits PDE5, allowing cGMP levels to rise, resulting in the relaxation of the smooth muscles of the penis.
When a man is sexually excited, this relaxing process allows increased blood flow in the penis in an erection that can be obtained and maintained for satisfactory sexual engagement.
