message: The section is confusing; it talks about Pfizer as if it were a drug, whereas Pfizer is the company that owns Viagra.

message: 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)

message: The article, presumably sponsored by Eli Lilly omits to mention that other brands of Tadalafil are available e.g. Forzest from Ranbaxy Pharmaceuticals.
Tadalafil is still under patent by Eli Lilly and a generic version is not available by Ranbaxy Pharmaceuticals. Similarly, Forzest is one of many "online" pharmacies located outside of the US that advertises "generic tadalafil".71.113.78.21 (talk) 13:11, 10 February 2008 (UTC)

thread_title:  Vision and Hearing Loss 

message: This article, like several others, makes the mistake of equating erectile dysfunction (ED) with impotence.  The latter is more often psychological in origin and in fact, the subject may be in perfect physical health and physically able to achieve a satisfactory erection if aroused.  On the other hand, most men suffering from ED alone can be sexually aroused, experience orgasm and ejaculate, even though they are not able to become erect.  If the subject has psychological or emotional issues that interfere with becoming sexually aroused, the entire supply of Cialis and Viagra in the known universe will be of no use.

message: Please forgive me for posting at the top, I have no idea of talk page etiquette but the molecular diagram seems to be missing all its hydrogen atoms.Moggyland (talk) 22:06, 11 January 2012 (UTC)
replies: text: The diagram is a skeletal formula and is the standard way that organic chemists depict chemical compounds such as tadalafil.  -- Ed (Edgar181) 22:08, 11 January 2012 (UTC)

text: Oh, sorry.  Hydrogen atoms are usually shown in that type of three-dimensional structure, but they are sometimes left out for clarity because it is the carbon framework rather than hydrogen atoms that contributes most to the overall geometry.  To me it doesn't seem necessary to omit them here, but shouldn't be harmful because anyone with the chemical knowledge to understand and/or use the diagram will recognize that the hydrogen atoms are implicit.    -- Ed (Edgar181) 22:19, 11 January 2012 (UTC)

message: This article currently starts with this:
"Cialis" redirects here. For the Central Asian kingdom, see Karasahr.
I went to that page and I cannot for the life of me discern how or why these two articles are related. Could someone offer an explanation? I presume there must be one, but if not maybe it should be removed? -- MyNameWasTaken (talk) 23:09, 28 February 2012 (UTC)
replies: text: Check Karasahr again. That article shows that the name "Cialis" appears on a 17th-century map, and was evidently "an Italianized transcription of the Turkic Chalish". This material has stood in the Karasahr article since October 2009, when the disamb. line you questioned was added to the Tadalafil article. -- NameIsRon (talk) 15:20, 10 November 2013 (UTC)

message: This article mentions the tablets are "enteric coated" (without any citation). We recently had a patient who inquired about splitting the tablets, I phoned up Eli Lilly and Company (NZ) Limited and they said the Cialis-brand tablets are NOT enteric-coated, there is NO sustained-release formulation whatsoever. They only cannot recommend halving the tablets because they haven't done any bioavailablity studies. All the sources I can find only mentions the tablets are "film-coated".
