Cialis is one of the world’s most famous treatments for male impotence, also known as erectile dysfunction, or ED. This medicine has been used for over a decade, treating erectile dysfunction successfully and ensuring hard erections in male patients using it as prescribed. It comes at doses of 2.5 mg, 5 mg, 10 mg and 20 mg.

Erectile dysfunction is a condition that can affect even quite young males. It involves a male patient being unable to achieve an erection hard enough to have sex. Another problem erectile dysfunction may display is inability to keep an erection for long enough to complete sexual intercourse.

The problem lies in the fact the penis does not fill with sufficient blood to help the man complete sexual intercourse. For an erection to occur, a certain sequence of events needs to occur. The brain sends electrical signals to the brain, causing the cells to produce nitric oxide. Nitric oxide is essential for the production of cGMP — another enzyme that relaxes the smooth muscles in the penis, helping it to inflate with blood.

As a result of those events taking place, the patient is able to achieve a harder erection and keep it for long enough to have sex. Not only does Cialis stimulate additional blood flow to the tissues of the penis, it also prevents the premature blood outflow by blocking the activity of PDE5, another enzyme responsible for decomposing cGMP.

The administration of Cialis combined with other treatments, especially nitrates, is not recommended, as life-threatening results are possible. If both treatments are to be combined somehow, at least 48 hours are supposed to pass between the two medications for the patient to be safe.
