Cialis, also known as tadalafil, treats erectile dysfunction (ED) by targeting a specific enzyme in the body.
Specifically, Cialis inhibits phosphodiesterase-5 (PDE5). This enzyme usually breaks down cyclic guanosine monophosphate (cGMP), a crucial molecule for achieving and maintaining an erection.
- By blocking PDE5, Cialis allows cGMP levels to remain elevated. Increased cGMP levels relax the smooth muscles in the penis. This relaxation increases blood flow to the penis, resulting in an erection.
The effect of Cialis is significantly different from that of other ED medications. Cialis’s effects can last for up to 36 hours, much longer than other medications. This extended duration results from its longer half-life.
This prolonged action offers greater flexibility in timing sexual activity. It doesn’t require precise timing relative to sexual intercourse.
However, individual responses vary. Factors like age, overall health, and the presence of other medical conditions can influence how Cialis affects a person. Always consult a healthcare professional before using Cialis or any medication for ED.
Remember to follow your doctor’s instructions carefully regarding dosage and potential side effects.
