Cialis and its working mechanism
Cialis is the brand name of Tadalafil, a PDE5 inhibitor used for treating erectile issues. Approved by the FDA in 2003, Cialis is known for its long-lasting effects, which can last up to 36 hours, earning it the nickname weekend pill. Additionally, it was approved for the treatment of Benign Prostatic Hyperplasia (BPH) in 2011.
The following points explain how Cialis supports erectile function by enhancing the body’s natural erection process:
- On sexual stimulation, Nitric Oxide (NO) is released in the body to increase the levels of cyclic Guanosine Monophosphate (cGMP).
- cGMP promotes muscle relaxation and widening of blood vessels in the penis. This, in turn, boosts blood circulation.
- PDE5, which breaks down cGMP, is inhibited by Tadalafil, thereby maintaining high cGMP levels and increased blood flow.
