[edit] Chlorthalidone vs. Chlortalidone

There seems to be some question over Chlorthalidone vs. Chlortalidone. The gent who forwarded Chlorthalidone to Chlortalidone indicated that the former was the spelling used in the UK until it was changed to the latter. My research seems to indicate something different. According to the Novartis web site, Chlorthalidone is a Thiazide-based diuretic (that is NOT marketed in the UK according to Novartis #1) and Chlortalidone appears to be a Sulfonamide-based diuretic marketed by Sandoz. Perhaps the spelling was changed in the UK because of the product difference between Novartis and Sandoz. I don't know so I have written to both manufacturers requesting clarification of the terms and usages. I will update these articles when I have more information: Hygroton, Chlorthalidone, and Chlortalidone. JimScott 01:46, 16 January 2007 (UTC)

Chlortalidone and chlorthalidone are, in fact, one and the same. Chlorthalidone was the British Approved Name (i.e., the name used in the UK) until 2004, when it was changed to the International Nonproprietary Name chlortalidone. (see this link) Unfortunately, to make matters worse, chlorthalidone is still the United States Adopted Name (i.e., the name used in the U.S.) According to Wikipedia's convention on naming of drug pages, articles should be named according to the INN whenever possible, hence the move to chlortalidone. Feel free to expand the article though, it's still only a tiny stub. Fvasconcellos 02:06, 16 January 2007 (UTC)
