While posters are legally responsible for their statements, the moderators may in their discretion remove or edit posts, though are not legally obligated to do so, regardless of content.

Users have the ability to modify or delete their own messages after posting. Moderators generally will not delete posts, threads or accounts unless they have been alerted and have determined that a post, thread or user has violated the Forums� policies. Moderators do not regularly independently monitor the Forums for such violations.

Profanity, outright vulgarity, blatant personal insults or otherwise inappropriate statements will not be tolerated and will be dealt with at the discretion of the moderators.

Users may provide their positive or negative experiences with or opinions of companies, products, individuals, etc.; however, accounts involving allegations of criminal behavior against named individuals or companies MUST be first-hand accounts and may NOT be made anonymously.

If a situation has been reported upon by a reputable news source or addressed by law enforcement or the legal system it is open for discussion, but if an individual wants to make their own claims of criminal behavior against a named party in the course of that discussion, they too must identify themselves by first and last name and the account must be first-person.

Criminal allegations that do not satisfy these requirements, when brought to our attention, may be removed pending satisfaction of these criteria, and we reserve the right to err on the side of caution when making these determinations.

Credible threats of suicide will be reported to the police along with identifying user information at our disposal, in addition to referring the user to suicide helpline resources such as 1-800-SUICIDE or 1-800-273-TALK.

2. Conversations in horse-related forums should be horse-related.
The forums are a wonderful source of information and support for members of the horse community. While it�s understandably tempting to share information or search for input on other topics upon which members might have a similar level of knowledge, members must maintain the focus on horses.

3. Keep conversations productive, on topic and civil.
Discussion and disagreement are inevitable and encouraged; personal insults, diatribes and sniping comments are unproductive and unacceptable. Whether a subject is light-hearted or serious, keep posts focused on the current topic and of general interest to other participants of that thread. Utilize the private message feature or personal email where appropriate to address side topics or personal issues not related to the topic at large.

4. No advertising in the discussion forums.
Posts in the discussion forums directly or indirectly advertising horses, jobs, items or services for sale or wanted will be removed at the discretion of the moderators. Use of the private messaging feature or email addresses obtained through users� profiles for unsolicited advertising is not permitted.

Company representatives may participate in discussions and answer questions about their products or services, or suggest their products on recent threads if they fulfill the criteria of a query. False "testimonials" provided by company affiliates posing as general consumers are not appropriate, and self-promotion of sales, ad campaigns, etc. through the discussion forums is not allowed.

Paid advertising is available on our classifieds site and through the purchase of banner ads. The tightly monitored Giveaways forum permits free listings of genuinely free horses and items available or wanted (on a limited basis). Items offered for trade are not allowed.

Advertising Policy Specifics
When in doubt of whether something you want to post constitutes advertising, please contact a moderator privately in advance for further clarification. Refer to the following points for general guidelines:

Horses � Only general discussion about the buying, leasing, selling and pricing of horses is permitted. If the post contains, or links to, the type of specific information typically found in a sales or wanted ad, and it�s related to a horse for sale, regardless of who�s selling it, it doesn�t belong in the discussion forums.

Stallions � Board members may ask for suggestions on breeding stallion recommendations. Stallion owners may reply to such queries by suggesting their own stallions, only if their horse fits the specific criteria of the original poster. Excessive promotion of a stallion by its owner or related parties is not permitted and will be addressed at the discretion of the moderators.

Services � Members may use the forums to ask for general recommendations of trainers, barns, shippers, farriers, etc., and other members may answer those requests by suggesting themselves or their company, if their services fulfill the specific criteria of the original post. Members may not solicit other members for business if it is not in response to a direct, genuine query.

Products � While members may ask for general opinions and suggestions on equipment, trailers, trucks, etc., they may not list the specific attributes for which they are in the market, as such posts serve as wanted ads.

Event Announcements � Members may post one notification of an upcoming event that may be of interest to fellow members, if the original poster does not benefit financially from the event. Such threads may not be �bumped� excessively. Premium members may post their own notices in the Event Announcements forum.

Charities/Rescues � Announcements for charitable or fundraising events can only be made for 501(c)(3) tax-exempt organizations. Special exceptions may be made, at the moderators� discretion and direction, for board-related events or fundraising activities in extraordinary circumstances.

Occasional posts regarding horses available for adoption through IRS-registered horse rescue or placement programs are permitted in the appropriate forums, but these threads may be limited at the discretion of the moderators. Individuals may not advertise or make announcements for horses in need of rescue, placement or adoption unless the horse is available through a recognized rescue or placement agency or government-run entity or the thread fits the criteria for and is located in the Giveaways forum.

5. Do not post copyrighted photographs unless you have purchased that photo and have permission to do so.

6. Respect other members.
As members are often passionate about their beliefs and intentions can easily be misinterpreted in this type of environment, try to explore or resolve the inevitable disagreements that arise in the course of threads calmly and rationally.

If you see a post that you feel violates the rules of the board, please click the �alert� button (exclamation point inside of a triangle) in the bottom left corner of the post, which will alert ONLY the moderators to the post in question. They will then take whatever action, or no action, as deemed appropriate for the situation at their discretion. Do not air grievances regarding other posters or the moderators in the discussion forums.

Please be advised that adding another user to your �Ignore� list via your User Control Panel can be a useful tactic, which blocks posts and private messages by members whose commentary you�d rather avoid reading.

7. We have the right to reproduce statements made in the forums.
The Chronicle of the Horse may copy, quote, link to or otherwise reproduce posts, or portions of posts, in print or online for advertising or editorial purposes, if attributed to their original authors, and by posting in this forum, you hereby grant to The Chronicle of the Horse a perpetual, non-exclusive license under copyright and other rights, to do so.

8. We reserve the right to enforce and amend the rules.
The moderators may delete, edit, move or close any post or thread at any time, or refrain from doing any of the foregoing, in their discretion, and may suspend or revoke a user�s membership privileges at any time to maintain adherence to the rules and the general spirit of the forum. These rules may be amended at any time to address the current needs of the board.

  • Esomeprazole (Nexium) for equine ulcers

    Ran across someone asking about esomeprazole for equine ulcers on FB awhile ago, and I went poking around to find this paper:

    https://www.researchgate.net/publica...gnesium_Nexium


    Dove was cribbing quite a lot after the move and Pigs is just prone, so I thought I'd try it.

    Nexium is ~$20 for 42 20 mg capsules on Amazon.

    I've been giving 3 capsules (60 mg) a day to each horse for about a week.

    I'm seeing FAR less cribbing in Dove...actually, I don't think I've seen her crib at all since we started. Pigs looks to be picking up, too.

    Treating a horse for four weeks at 60 mg/day = 40 bucks.

    Overall has been a successful experiment for me and my horses so far. Curious to see if it's ever brought to the equine market. Would love to see a vet doing a scoping study with it!

    esomeprazole is just the S-enantiomer of the racemic omeprazole. There is no reason it wouldn't work, but it is more expensive than omeprazole at treatment doses for horses. I'm glad it's helping your horse!

      HiJumpGrrl, please read the paper I posted above. The full text is there. Demonstrated that 40 mg and 80 mg doses were equally effective at raising the pH. 60 mg/day = 40 bucks for the month. Hardly more expensive than omeprazole.

      There is the risk that the horse will crunch the capsule and negate the coating. But by dosing 60 mg/day, they can totally obliterate one capsule and I still have an effective dose.

        Nexium is a capsule. It's in capsule form so that it is not broken down in the stomach but reaches the hindgut or in a human's case the small intestine where it can be absorbed. I would think you'd have to open the capsules to give them to horses in which case the medication would not get back to the hindgut where it needs to absorb to be utilized.

          I drop the capsules, intact, into the grain. Horses certainly don't chew everything.

          Not much different than hoping Abler pop rocks don't get chewed on the way down. The capsules are teeny.

            Ok, read the paper. Interesting.

            I wonder if the much lower effective dose could be further applied with omeprazole. I know they determined that 1/4 tube of gastroguard (or ~570mg) was equally effective as a full tube with that paper last year; could it be further reduced with equal outcomes? Nexium is twice as potent, so 60mg esomeprazole = 120mg omeprazole... or about 1/19 of a tube.

            Also, they did not show that the decreased acid production enough to be associated with ulcer healing--I didnt' read that the higher pH observed is clinically enough to promote healing, but maybe I missed that small picky piece of information.

            in human medicine, Nexium and Prilosec are equivalent treatments, and arguments have been made that Nexium should never have come to market at all.

              The Australian study didn't use GastroGard--it used an enterically coated granular paste product that's not available in the US. Enterically coated preps have higher bioavailability than buffered preps, so that study really isn't applicable to GastoGard at all.


              Also, they did not show that the decreased acid production enough to be associated with ulcer healing--I didnt' read that the higher pH observed is clinically enough to promote healing, but maybe I missed that small picky piece of information.
              Nope, they didn't. Let's go look at the GastroGard data...

              https://www.ncbi.nlm.nih.gov/pubmed/14649361

              pH >4.

              The esomeprazole definitely hits that.


              Oh, the >4 number is also in the abstract of the esomeprazole paper.

                Hmm, interesting. Thanks for the share. I may have to try this out with my ulcer-prone sensitive redhead. We have an impending move. Even just doing some weekly trailer loading practice has her slowing down on her feed. I plan on putting her on at least a maintenance dose of omeprazole for the move, but this may be an economical way to keep her stomach happy until that time. Just our cleaning up the property sends her into a tizzy. "Oh my god, why are you removing that big pile of brush? Oh my god, why are you cleaning the junk out of the barn??? I like that junk there!"

                  Try it, Tex! Report back Oh, the joys of moving with touchy horses

                  When I bring them off of it, I do intend to carefully taper. If it's so effective at stomping on those proton pumps, I could see that there might be an impressive acid flare if removed suddenly.

                      Reporting back that this really seems to be going well. Piggy has put on a considerable amount of weight and Dove's cribbing is back to her usual "cigarette after a meal" baseline that is normal for her. Really, zero complaints about this super easy and cheap method of treating ulcers.

                      Although I certainly haven't scoped, I would call it a success based on symptoms.

                          What generic?

                          Esomeprazole is Nexium. It is still under patent. I don't think any generic has been discussed on this thread.

                            Well excuse me. I assumed as with Omeprazole (non generic Prilosec)there might be a generic option and was just asking as I was interested. I'll continue on my own.

                              Generic esomeprazole approved in 2015 by the FDA.

                              this is a company making generic.

                              Hope this helps.

                              I too am interested in Simkie's testing, because I have an ulcer-prone horse.

                                I tried to post a reply it told me 'unapproved'.

                                Perhaps because I did find generic Nexium and tried to post a couple of links. Anyway, a google searched turned up that in 2015 generic esomeprazole was approved by the FDA.

                                Hope that helps.

                                  Ah, interesting. Didn't realize. Looks to have limited distribution, and only by RX.

                                  With Nexium being so cheap and OTC, I'm not surprised a generic hasn't garnered a whole lot of interest.

                                    Both esomeprozole and omeprazole need to have enteric coatings, so that they pass thru the stomach unaltered.

                                    With horses, chewing and saliva can disable any enteric pills.

                                    According to that study the Esomeprazole was administered thru a nasal gastric tube (NGT) 30 min prior to eating in the AM.

                                    Did you give it 30 min before their AM feeding?

                                    If you still have some of the capsules, can you tell if they have little enteric coated beads inside, or is the capsule the enteric coating?

                                    I wonder if a balling gun would work? Could one maybe do all 3 caps at once if they are little.

                                      Can you share how you administer it to your horses? Did you give it 30 min before their AM feeding?
                                      I drop the three capsules in their grain, which they get when they come in at night. There is certainly the risk that they'll chomp through a capsule, but that's why I went with 60 mg instead of the 40 that was found effective in the study--they can totally obliterate one capsule and I still have an effective dose.

                                      I do wet my grain, but I don't add the pills until the horses are eating and do my best to add to a "dry" spot.

                                      Horses are generally milling about and not eating for awhile before coming in, so that's about as close to "empty stomach" as it gets around here. They have hay available 24/7.

                                      I realize isn't ideal, or study parameters, but it really isn't any different than using the Abler pop rocks and just hoping that the horses don't chew them and that the wet grain doesn't trash the coating.

                                      You could easily up the dose or use a balling gun to deliver the capsules to the back of the tongue, were you so inclined.

                                        Well, you would think so. As a pharmacist it has puzzled me that several of these drugs that only have the "active" enantiomer or isomer are still dosed at the same dose as the older drug that had the active & inactive forms. I wasn't sure about omeprazole vs. esomeprazole, so I just looked up and compared doses for 5 indications that both drugs have. The dose was the same for both for all indications.

                                        Now that my boy has been off Ulcergard for a month or so, it seems his symptoms may be coming back. I think I'll be giving Nexium a try.
                                        That's fine, many of us have slid down this slippery slope and became very happy (and broke) doing it. We may not have a retirement, but we have memories ...
