What Is Cialis?
Cialis is a prescription medication that's manufactured and sold by Eli Lilly and Company. It’s used to manage the symptoms of erectile dysfunction and was first approved for use in the United States on November 21, 2003. It's since gone on to become the strongest competitor to Viagra®, which was the first medication approved to treat ED.To get more news about 正品犀利士哪裡買, you can visit our official website.

Although Cialis is still second to Viagra, it's made up a lot of ground in recent years, and together these two medications make up roughly 95 percent of the market for erectile dysfunction treatment.

What Is Erectile Dysfunction?
Erectile dysfunction is when a man has difficulty achieving or maintaining an erection that's firm enough for sex.

Nearly every guy will experience ED or symptoms like it at one point or another. It’s completely normal for the occasional issue to occur, but if these issues become the norm it's generally considered erectile dysfunction.

Erectile dysfunction is really a term for symptoms, and ED does not have a singular cause. It's usually a symptom of other medical conditions, often the result of a physical condition that has a negative impact on your circulatory or cardiovascular system. It can be caused by psychological issues as well. It’s important to note that taking prescription medications for erectile dysfunction will not "cure" ED. These drugs are meant to help manage the symptoms of ED and help guys get an erection, and they work very well for most men.

How Does Cialis Work To Treat ED?
The active ingredient in Cialis is tadalafil, which is a phosphodiesterase type 5 (PDE5) inhibitor. All of the popular medications for erectile dysfunction – including Viagra (sildenafil) and Levitra® (vardenafil) – belong to this drug class and work in a similar way.

The PDE5 enzyme is found in blood vessels and usually acts as the "breaking system" on your erections. The enzyme helps return your penis to flaccid after an erection and orgasm.

PDE 5 inhibitors block this enzyme to help keep blood vessels dilated when you're aroused. This helps to increase the volume of blood flowing to your penis to achieve an erection more easily and to stay erect for longer.

The major difference between Cialis and the other PDE5 inhibitors is how and when it's taken. Cialis is the only medication that can be taken daily in a low dose or "on-demand" when you're preparing for intimacy. Viagra and Levitra are both intended for use as needed in the 4 hours prior to sex.

Cialis in its higher doses (5, 10, and 20 mg) is used on-demand as well, though it's effects can last for 36 hours or more. For this reason, Cialis is often preferred over other medications when men and their partners get to try more than one.
