What Does Cialis Do?

You probably know or have heard that Cialis is used to treat erectile dysfunction in adult men. You may also have heard that Tadalafil, the active ingredient in Cialis, is used to treat some heart or blood related conditions, or as preventative measure for other diseases and symptoms.

You may still wonder, though, what exactly Cialis does. How does it help with erectile dysfunction, or any of those illnesses and conditions listed above? How does Tadalafil work? Here is a brief overview of how Tadalafil – and Cialis – works, and how that helps with certain blood-related issues.

What It Does

Cialis’s main and only active ingredient is Tadalafil. It is a vasodilator, which means that it relaxes the blood vessels and muscles to encourage and increase blood flow to certain regions of the body. In the case of Cialis, this means encouraging blood flow to the groin and penis to help maintain erections. However, Cialis (and Tadalafil) do not create erections; they simply help keep the blood flowing in that direction once the person is aroused.

Tadalafil is considered safe in the right dosage, but it should still be taken with caution. Increased blood flow can potentially cause dizziness or disorientation if your body in unused to proper or increased circulation, so that is something to bear in mind when using Cialis.

How It Works

How does Cialis achieve the goal of increased blood flow? Here is some of the actual biological/chemical science behind exactly how Tadalafil works.

Erections occur because of increased blood flow to the penis, which is a result of dilated blood vessels going into the area and contracted blood vessels leaving the area, causing the blood to “accumulate” – this is the basic scientific description of an erection. Cialis allows for the relaxation of the blood vessels entering the penile region, so when a man taking Cialis is sexually stimulated, he can maintain an erection much easier than he previously could.

How exactly does this happen, though? When sexually stimulated, the body releases nitric oxide into the penis. This chemical compound then enables the production of something called cGMP, or cyclic GMP. cGMP is what relaxes smooth muscle and widens the blood vessels in the corpus cavernosal area, which is where the penis is. The substance that causes the loss of an erection is called PDE5. PDE5 destroys cGMP, causing the blood vessels to contract once more and for the erection to disappear.

Cialis inhibits the production and release of PDE5, causing an upsurge of cGMP. This allows the cGMP to do what it does best and help keep the erection long-lasting. PDE5 is also part of the arteries in the walls of the lungs and heart areas, which is why Cialis, or Tadalafil, is also used to treat certain conditions in that area.

The Bottom Line

Whether you are interested in the actual mechanics of Cialis or not, the fact of the matter is that Cialis is successful. It has been proven to help many adult men maintain erections for longer or maintain them at all. It does the job, and it really does work.
