thread_title: Contraindications?

message: What I have drawn is, actually, the correct structure of S-omeprazole. The S designation of this molecule is with respect to its structure in vivo - where the sulfinyl moiety is ionised, and there is an additional hydrogen substituent off the chiral sulfur. Under these circumstances the stereochemistry is clearly S. So whilst, technically, this drawing may be R, it actually does represent the structure of S-omeprazole.Techelf 11:14, 21 Oct 2004 (UTC)
replies: text: I do not agree. Omeprazole is the compound we have in the Nexium bottle. The formula here represents R-omaprazole, therefore it should be fixed. You might make a mistake when redrawing the formula, you pribably did functional group/molecule rotations and have forgotten to follow this motion and change the stereo bond type. Try to imagine the molecule in 3D-space :). If I'm wrong (I'm almost sure I'm not) please give me some reasonable explanation. Regards, Mykhal 14:33, 22 Oct 2004 (UTC)

text: I concede the point and have revised the drawing accordingly. I had initially (wrongly) supposed that the orientation of the substituents off the chiral sulfur was of a trigonal planar configuration; therefore I had assumed that the orientation of the oxygen substituent would not make a difference. In retrospect, I've realised that the sulfur substituents have a tetrahedral configuration; so you are right about the oxygen substituent being inverted - well spotted.

replies: text: Thank you. I know, this is not obvious, that on the sulfur atom is lone electron pair which is the fourth "substituent" with lowest priority.. Mykhal 08:49, 23 Oct 2004 (UTC)
thread_title: What

message: The following information from the DrugBank should be incorporated (not copied!) into this article:
"Esomeprazole is a compound that inhibits gastric acid secretion and is indicated in the treatment of gastroesophageal reflux disease (GERD), the healing of erosive esophagitis, and H. pylori eradication to reduce the risk of duodenal ulcer recurrence. Esomeprazole belongs to a new class of antisecretory compounds, the substituted benzimidazoles, that do not exhibit anticholinergic or H2 histamine antagonistic properties, but that suppress gastric acid secretion by specific inhibition of the H+/K+ ATPase enzyme system at the secretory surface of the gastric parietal cell. Because this enzyme system is regarded as the acid (proton) pump within the gastric mucosa, Esomeprazole has been characterized as a gastric acid-pump inhibitor, in that it blocks the final step of acid production. This effect is dose-related and leads to inhibition of both basal and stimulated acid secretion irrespective of the stimulus."
I'll probably do it myself eventually, if no one else does. Fuzzform 02:13, 22 February 2006 (UTC)

message: I have noticed that Esomeprazole shares metabolic mechanisms with other drugs such as Clonazepam, and SSRIs like Escitalopram and Citalopram. Can someone look up if there is expected to be heightened serum levels of these drugs while on Esomeprazole due to their shared hepatic clearance mechanisms? If so, I think this should be included in this article. Please include with a source. --1000Faces (talk) 16:16, 1 December 2009 (UTC)

thread_title:  Interaction with other drugs, e.g. SSRIs? 

message: Is there any literature which cites the dosage equivalency of omeprazole to Esomeprazole?  For example, if someone were to switch from 40mg of Esomeprazole, should they switch to 10, 20, 40, or 80mg of omeprazole? If there is data in the literature on this, I think it should be mentioned here. It is touched upon during the Controversy segment, but lacks conclusive statements. --1000Faces (talk) 04:25, 2 December 2009 (UTC)
replies: text: They're more or less the same thing biochemically, so they're equipotent; the main difference between them is price and patent protection; see the NBC correspondent's comment quoted below. --Elvey (talk) 09:26, 4 June 2012 (UTC)
replies: text: Do you have a source that clearly states they are equipotent?  If so, we need to add that to the article.  yoyo (talk) 01:47, 14 February 2017 (UTC)
thread_title:  Dosage equivalency with omeprazole? 

message: :However, a more proper comparison would be with an 80 mg dose of omeprazole because this would contain approximately the same amount of the active enantiomer. However, there are also indications, as shown above, that for omeprazole, both the (R) and (S) enantiomers have the same therapeutic effect. In that case the comparison is valid after all.
If someone can find a source that points this out, it would be useful to have in the article.  As it stands now however it's not cited. hbdragon88 (talk) 01:37, 5 January 2010 (UTC)
thread_title:  80mg comparison 

message: Hey All,
Sorry I am in a rush and am unwell so cannot make the amendment myself but the structural diagram for Esomeprazole is clearly wrong. The fact that the molecule has 3 oxygen atoms but only two are present in the figure is a stark example of just one of the couple of mistakes I witnessed. If someone with more knowledge and experience than myself could please rectify the issue that would be great.
Thanks,

replies: text: This was exactly the incorrect structure that motivated me to register as a Wiki contributor :) I fixed this while I was on holiday in Italy. At the time I didn't even realise articles had talk pages like this to identify such issues. I'm pretty busy with research so I don't have time to contribute much, but I enjoy adding stubs (with structure and basic cited details) for medicinal molecules that might be generally interesting to the community.

thread_title:  largely redundant Intro 

message: Hi, I am confused about the USFDA Pregnancy Category of Esomeprazole. Some places state it as Category C while others are stating it as Category B (http://onlinelibrary.wiley.com/doi/10.1111/j.1745-7599.2007.00302.x/full, http://www.accessdata.fda.gov/drugsatfda_docs/label/2010/022101s004,021153s034,021957s007,021689s015lbl.pdf). I think that a section on this topic would be helpful to many. However, I would prefer not to edit myself as I may not be most suited to edit. I hope editors of this page will consider adding a section on this.
Thank you.

thread_title:  Pregnancy Category of Esomeprazole 

message: the following is unsourced - moved here per PRESERVE
The granules are manufactured in a fluidized bed system with small sugar spheres as the starting material. The sugar spheres are sequentially spray-coated with a suspension containing esomeprazole, a protective layer to prevent degradation of the drug in manufacturing, an enteric coating, and an outer layer to reduce granule aggregation. The granules are mixed with other inactive excipients and compressed into tablets. Finally, the tablets are film-coated to improve the stability and appearance of the preparation.

replies: text: I already explained it in my most recent edit summary: "The problem is that it's really not notable enough or even similar enough for mention here". Who cares about some random cult that doesn't even have the same spelling as Nexium? Its mention is unencyclopedic for this article. --Acyclic (talk) 21:46, 22 April 2018 (UTC)

text: Maybe I should start a cult named PRLSC while I'm at it for top mention in the omeprazole page. --Acyclic (talk) 21:48, 22 April 2018 (UTC)
replies: text: People who only hear the name without seeing how it's spelled may come to Wikipedia searching for info on it, and there's a good chance they'd end up on this page. Lizard (talk) 22:24, 22 April 2018 (UTC)

text: At the very least, it's useful at the moment; NXIVM received over 200,000 views yesterday as the group is receiving heavy publicity right now. I'd have no objections to removing the hatnote in a few months once the hoopla has died down. Lizard (talk) 22:32, 22 April 2018 (UTC)

text: Acyclic, if you do start such a cult and it gets major media coverage, we would make such a hatnote. You haven't.  NXIVM did. It is totally appropriate to have the hatnote. Jytdog (talk) 03:01, 23 April 2018 (UTC)
replies: text: The name NXIVM is just too different from Nexium, so the argument for the hatnote is weak. Anyhow, the NXIVM article still has a lot of page hits, so I'll wait the hits subside. --Acyclic (talk) 02:18, 28 April 2018 (UTC)
