This article states that Lilly bought Icos in 2006. That is incorrect. Icos still has not been purchased and maybe never will.----

As with Levitra, I just had to put that bit in about what to do if a certain body part remains hard for more than four hours.

Levitra and cialis difference

Levitra and cialis both are PDE5 inhibitors and in which way do they differ in performance, price, customer satisfaction, Any clarifications please?

Comparison with other drugs

I've made a request for more information about how this drug compares to similar ones. I think other people would like to know more about this too. Thanks to anyone who can help. Eje211 16:57, 9 May 2006 (UTC)[reply]

A great in-depth article can be found here, in which the three drugs are compared. Tadalafil has a different binding-mode than Sildenafil or Vardenafil, which are structurally very similar.

Cialis Drug History cleanup

The section is confusing; it talks about Pfizer as if it were a drug, whereas Pfizer is the company that owns Viagra. The statement that Cialis works for up to 36 hours occurs twice in the last two sentences. And the whole thing needs to sourced. -- Donald Albury 10:17, 28 October 2006 (UTC)[reply]

cleaning...

Corrected the confusion between company (Pfizer) and drug (Viagra). The statement about the effect duration depends on the half-life of the substance. Both the mesured halfe-life and the advertised effect duration can be found in any drug data base. The problem is : most drug database are restricted to physician. The few public I know are in french. I don't know which source to mention here. Help ! DrYak 13:36, 24 November 2006 (UTC)[reply]

If you don't know of any publicly accessible source in English, cite a French one. If someone finds a source in English, it can always be added then. .-- Donald Albury 16:48, 24 November 2006 (UTC)[reply]

Niagara means 'waterfall' in latin??

According to this article the word "Niagara" means 'waterfall' in latin. But according to the Niagara Falls article, "The name "Niagara" is said to originate from an Iroquois word "Onguiaahra" meaning "The Strait." " SO WHATS THE DEAL???

Another reading of that sentence is that the name Viagra is derived from the Latin vita and from the name of the waterfall, which does not imply that 'Niagara' is from Latin. However, the whole thing is unsourced. -- Donald Albury 11:05, 26 November 2006 (UTC)[reply]

Spam

How about a section that says something like "Cialis has a bad reputation for being offered through spam"? --71.125.20.130 21:39, 15 December 2006 (UTC)[reply]

As opposed to all the other drugs that are not offered through e-mail spam? -- Donald Albury 02:20, 17 December 2006 (UTC)[reply]

Causes erections?

"...caused the heart patients that were participating in a clinical study of a heart medicine to have erections..."

Surely this is wrong or incorrectly phrased?

The FDA-approved package insert[1] for Cialis says "Some form of sexual stimulation is needed for an erection to happen with CIALIS." Dpbsmith (talk) 13:10, 30 December 2006 (UTC)[reply]
