What is Cialis and how does it work?

Cialis is a tablet that treats erectile dysfunction. It does not increase sexual desire or cure erectile dysfunction, but it does help men to have and maintain erections.

When you have an erection, increased blood flows into the penis, creating pressure that causes the penis to expand. With erectile dysfunction, this process is interrupted, resulting in limited blood flow that prevents the penis from becoming erect. This is where Cialis can help.

Cialis is a PDE5-inhibitor, meaning that it inhibits the phosphodiesterase type 5 enzyme. When this enzyme works too quickly, it prevents the muscles and blood vessels in the penis from relaxing, which decreases blood flow. By blocking this enzyme, tadalafil – the active ingredient in Cialis –relaxes the muscles and blood vessels, increasing blood flow to the penis. It also boosts the naturally occurring chemical nitric oxide, which helps to increase blood flow as well.

Cialis will not cause you to have an erection; sexual stimulation is required for the drug to work.

With stimulation, Cialis improves the ability to get and maintain erections during sexual intercourse. This can lead to longer and firmer erections, and improve overall sexual satisfaction. In addition to the main physical function of Cialis, it can also help to alleviate the mental stress and anxiety that erectile dysfunction may cause in some men.

Cialis remains in the bloodstream for 17 to 18 hours. It can be effective in as little as 30 minutes and as long as 36 hours after use. After sexual intercourse has finished, the erection should go away. In the rare event of an erection lasting more than four hours, you should seek immediate medical help.

Cialis is one of the UK's most effective, medically proven treatments for erectile dysfunction.
