Forum rules and no-advertising policy

As a participant on this forum, it is your responsibility to know and follow our rules. Please read this message in its entirety.

Board Rules

1. You’re responsible for what you say.
As outlined in Section 230 of the Communications Decency Act, The Chronicle of the Horse and its affiliates, as well Jelsoft Enterprises Ltd., the developers of vBulletin, are not legally responsible for statements made in the forums.

This is a public forum viewed by a wide spectrum of people, so please be mindful of what you say and who might be reading it—details of personal disputes are likely better handled privately. While posters are legally responsible for their statements, the moderators may in their discretion remove or edit posts that violate these rules. Users have the ability to modify or delete their own messages after posting, but administrators generally will not delete posts, threads or accounts upon request.

Outright inflammatory, vulgar, harassing, malicious or otherwise inappropriate statements and criminal charges unsubstantiated by a reputable news source or legal documentation will not be tolerated and will be dealt with at the discretion of the moderators.

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.

  • Is Abgard As Effective as Gartrogard?

    Basically what the title says. Is the Abgard, much cheaper, the same as the Gastro/Ulcergard in treating ulcers, then switch to Abprazole for maintenance?

    My vet thinks its exactly the same. I'm treating with Abgard and I'll be repeating the scoping in the end of the month, so I can post then.

      What is Abgard....do you have a link or website info

      Comment


      • #4
        Abgard is the proper name for the "blue pop rocks" from www.omeprazoledirect.com

        A head to head trial will NEVER be performed, as Gastrogard is due to come off patent within a year or two and will then become generically available, at which point the billion-dollar cash cow will dry up considerably. (although don't count on the price coming down quickly)

        It would also behoove NOBODY other than Abler Rx to perform such a study, and that is not the business that generic drug manufacturers are in.

        So it remains up to the individual to decide for themselves if they "trust" that the generic product is up to the same standard as the brand name.

        I use the pop rocks and have a fairly significant comfort level that they do what they are supposed to do. But I don't have any "proof" in terms of large series of animals with documented ulcers treated with one or the other with repeat scoping to show improvement. That is what it would take to be sure, and again those studies will never be done.

          The pop rocks are not Abgard, they're Abprazole and actually work in a different way then Abgard and Gastrogard.

            Actually the "blue pop rocks" are Abler (company) but the drug is still omeprazole I am not sure what Abgard is, but omeprazole is omeprazole which is the ingredient in GG that heals the ulcers.

            What mostly matters for this is to make it past the stomach acid so the drug must be coated in a way that saves it from being destroyed in the stomach and be absorbed later.

              Abgard is Abler's paste omeprazole. I don't know how it is protected from digestion. We know the pop rocks have enteric coating but assume they buffer the paste somehow.

                My apologies for mixing up Abgard and Abprazole! Mea maxima culpa . . . I was not aware their (newish?) paste had a different name.

                  Just wanted to add - a natural item used often in racehorses for preventing stomach ulcers is Papaya Juice. Horses love the taste of it and it seems to work well. Much cheaper than Gastrogard. We typically would give 40-60mL of Papaya 2X/day. (bigger the horse, the closer to 60mL we gave) I never met a horse that wouldn't happily slurp Papaya juice out of the syringe. :-) Just thought I'd mention it!

                    They work the same (theoretically) - its just the vehicle for getting the omeprazole safely to where it needs to be is different.

                    Paste - one would assume they have a buffering ingredient, so the stomach pH is changed so that the omeprazole is not "killed" in the stomach. Then, the omeprazole safely makes it through, then starts its job by limiting acid production.

                    Granules - they have a coating so the stomach pH doesn't need to be changed to get them to where they need to go. The coating protects the drug, it gets through the acidy stomach, then goes to work.

                    Either method: eventually, once the omeprazole starts working and the acid stops being produced, you could techically administer unbuffered, uncoated omeprazole and it would continue to work...because there's no acid in there to "kill" it.

                      This statement is completely incorrect. In order for a generic company to bring another omeprazole paste version to market, they WILL need to perform bioequivalence studies to show the two formulations perform identically. This would be filed as an ANDA to the original NDA.

                      If a generic company wants to bring a new dosage form to market (ie, coated granules), they would need to do so under a 505b2 filing. This kind of filing is more costly in and of itself (filing fees to FDA), and would require a more complete data package to submit than an ANDA (ie, more studies completed). A company could also potentially challenge Merial under a Paragraph IV filing, but that has high financial risks.

                        By head to head I meant a large, randomized, blinded clinical trial. But perhaps you can help me understand--when "bioequivalence" needs to be demonstrated, are there large enough numbers of subjects to actually demonstrate noninferiority in terms of ulcer healing, or is some other metric used like plasma drug levels?

                          I guess what I have been trying to figure out is the suggested TREATMENT to cure ulcers is Gastro/Ulcergard paste for a month and then I see a lot of folks use the pop rocks for continued prevention. Or, I also see that you can give three packets (for my size horse) of the pop rocks for TREATMENT & then reduce as decided for prevention. I am trying to decide to try Aber's Abgard paste first for treatment & then go with the pop rocks for prevention, or just go with the pop rocks. Obviously, I would like to go the most effective route, but also as cost efficient as I can.

                          I have not had my horse scoped to confirm ulcers. The only signs he seems to be exhibiting has been increased spookiness that has accelerated over the past year & maybe some sensitivity under his belly when I bathe & scrape with the sweat scraper.

                          This is a horse that was dead head quiet on the trails and now is very reactive, mainly to deer crashing in the bushes. He used to just sort of startle in place & snort. Now he has become hyper vigilant and will do the wheel sideways & spin. I had myself convinced it has been because our deer population in NO. VA has so gotten out of control those Crackhead Bambis travel in gangs & burst as a herd out of nowhere. My lovely, quiet trail rides hacking on the buckle are a thing of the past.

                          He's better hacking out with company, but still spooks more than he used to. He's a fabulous eater, almost too much of an easy keeper so he gets a small amount of low NSC feed, a couple of small flakes of alfalfa when stalling inside during the summer & turn out on pasture in the evening currently. He doesn't seem like a prime ulcer candidate, but I'm willing to try the ulcer treatment to see if it makes a difference.

                          I might be grasping at straws, but I'm trying to get inside his head or maybe his stomach to get the quiet guy I used to have back. He used to love to go out on the trails by himself. He still will, but spends a lot of the time being bug eyed.

                          Suggestions appreciated!

                            Drugs being filed under an ANDA (ie, generic) do not need to go through the various levels of clinical trials and toxicity studies in animals, healthy subjects, and patients the way innovator NCE (new chemical entities) do, as per provisions under the Hatch-Waxman Act. They DO need to demonstrate bioequivalence to the innovator.

                            BE is determined through measuring plasma concentrations in evaluating the PK (pharmacokinetics) of the two products in healthy subjects, with a 90% correlation to the innovator being considered "equivalent". But, as with much of FDA guidance, there is a lot of room for interpretation. A company can try to submit analytical and dissolution data only if there is an IVIVC established (in-vivo in-vitro correlation, which basically means that the drug can be expected to perform in an analytical dissolution test method as it would in an actual live body. This is only appropriate for certain types (BCS 1 drugs- highly soluble, highly bioavailable- and only certain formulations of drugs (oral suspensions, IR tablets).

                            Because omeprazole is drug that requires an MR (modified release), not only does FDA request BE studies, they would want both "fasted" (subject takes med on empty stomach) and "fed" (patient takes med on full stomach) to assess the impact of what is called the "food effect".

                            I do not have a good understanding of HOW MANY patients would be required for BE studies, especially in horses/ veterinary medicine. I've seen numbers as low as 25-30 subjects in human trials, but I can imagine this would range up in to hundreds or thousands for certain types of drugs/ indications.

                            I am quite certain a generic company has the BE studies and filing ready to go for the day the Merial products come off patent. The formulation of the product is fairly simple. It's the regulations that are lots of red tape to get through.

                            (sorry to derail your thread OP- either product should work as well as the other; it depends whether the granules or paste fit into your care program more easily. I would give the higher dose for treatment, and the lower dose for prevention in stressful situations.)

                              NO doubt. I was sort of angling my line of thought towards the Abler product and its status as a semi-outsider since it is sort of dodging US FDA oversight by being manufactured overseas and imported "privately", if you will. Wondering if that company has any intention of going through the process you describe when the time comes. (yes, a rhetorical question to which I don't think anyone here can reply) But thank you for clarifying my points and educating me some more.

                                No problem. I'm actually at a conference in New York right now, and over a break I chatted with a colleague of mine who specializes in generics. He said basically the same thing that I thought re: what is required for BE studies - "it depends" (on drug type, classification, indication, etc)

                                I got curious myself about the nuances for veterinary medicine, so I just looked up FDA's Guidance for Industry for Abbreviated New Animal Drug Applications (ie, generic animal drugs). It also doesn't make mention of the number of subjects required, but does talk about preferred methods of studies (blood plasma) vs PK or clinical endpoints, and the need for positive, negative, and test controls.

                                It would be interesting to know if Abler plans to file with FDA- perhaps they are even already one of the generics lined up with their ANADA ready to go once the patent runs out. It would be even more highly interesting to know if the "COTH effect" is causing enough of a ripple in Merial's sales of UG/GG such that Merial would be motivated enough to try to get FDA to do something about the, ahem, private importations, in advance of the patent expiration.

                                  For the cost that a run on Abler would cost in legal and administrative fees, they could just drop the price of the danged drug 20% and come out even.
