What is Cialis ?

Cialis (tadalafil) is a medicine used to treat the physical problem of erectile dysfunction (impotence) in men. Cialis is in a class of medications known as PDE-5 inhibitors, which are used to treat cases of male impotence. It can help a majority of men with erectile dysfunction get and keep an erection when they become sexually excited. Cialis does not cause erections directly but affects the response to sexual stimulation. It is not an aphrodisiac or a hormone.

Take it once and it lasts all weekend -- In Europe , where Cialis was launched on February 5, 2003 , it has been dubbed the weekend pill: "Most men tell us they don't like to have sex timed to a pill," said Lilly spokeswoman Carole Copeland. "Cialis is allowing men to return to a more normal type of sex life, to choose the moments when they want to have intimacy."

According to clinical studies data on Cialis(TM) (tadalafil), men with ED reported a statistically significant improvement in successful intercourse attempts at 24 and 36 hours after taking the drug, compared to placebo. Other new findings -- including a summary of cardiovascular safety data showed no increased incidence of cardiovascular events during clinical studies. In all studies, compared with placebo, use of Cialis® demonstrated consistent and statistically significant improvement and the treatment effect did not diminish over time.
