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.

Please see our full Terms of Service and Privacy Policy for more information.

      Pentosan Gold is done IV, but I think the OP is talking about regular Pentosan.

      Incidently I just read an article about a racehorse dieing from the Pentosan Gold - anaphylactic reaction. I'm sure that's the 1 in 1 million, but makes me nervous to administer the first time without the vet present.

          I need a primer on Pentosan, please. I've got a mare who has just been diagnosed with stifle arthritis. Vet is pushing Adequan, but is willing to write a script for Pentosan. Prices are all over the map.

          What's the best and cheapest source for Pentosan? Does it need to be the stuff with the green label? I've seen it for sale with other label types and was assuming it would be a compounded version.

          Please point me to a reliable seller.

              My vet used regular pentosan. According to the package insert he gave me, pentosan can be administered IM, IA or IV. If it produces results, I'll get a prescription and do it myself IM.

              Pentosan gold is pentosan and an adequan analog. It is also available as pentosan gold+ HA.

                Pentosan gold is pentosan plus injectable glucosamine. If that's an adequan "analog" then lighter fluid is an analog of gasoline. Wouldn't put the former in my gas tank.

                I hope people are getting advice from vets who know precisely what they're prescribing and doing with these drugs, and why.

                Can't fathom why one would want to risk giving it IV if there is a safer method.

                  We just started my 16 year old hunter on this yesterday, so I've been reading this thread with interest. I've also read through many of the various threads on Pentosan. My vet's instructions on the prescription/bottle/bag read 6ml IM or IV every two weeks. I gave it IM, as all the IV horror stories make me run screaming--and I, too, can't fathom the IV choice. I was billed, so I've no idea what Dr. is charging me yet, but I know it is far less than Adequan/Legend would be, which makes me happy. I was not happy with the results of Adequan, so I'm anxious to see if Pentosan is a better choice for my boy.

                    Adequan is polysulfated glycosaminoglycan.
                    Pentosan gold contains n-acetyl glucosamine.
                    Analog -
                    a chemical compound with similar properties.
                    Both compounds are used to treat
                    osteoarthritis.
                    Both compounds have a potentiating effect on haluronic acid formation.
                    n-acetyl glucosamine has been shown to have a beneficial effect on some auto immune processes.

                    Regarding the method of delivery, I don't usually argue with my vet about that stuff, but I'll ask him about it

                        It is NOT completely risk free. For one thing, there is a moderate anticoagulant effect that may not be an issue in many individuals but can certainly be VERY undesirable in others. [/QUOTE]

                        HOs: Is this the big known side-effect of Pentosan? Are their others? I spoke with a vet about it for my old man (vet/horse are on the other side of the country) and she didn't want to use it because of side effects. We didn't get so far as to talk about what those were.

                        By I'm bold, I want good quality of life for the horse as long (or as short) as that is, and the horse has no financial value. So what's the hubbub with the side effects?

                          I think people are confusing RISKS with SIDE EFFECTS. A "side effect" is an unintended reaction or effect of a drug, like getting drowsy from an antihistamine when what you wanted was to stop sneezing. Even if they're common and predictable, they're still side (not the primary) effects of a drug.

                          RISKS are things like anaphylaxis or infection from the injection of a drug, etc. You could argue that bleeding would also be a "side effect" of a drug like Pentosan, as it is unintended but in the nature of the drug to produce bleeding.

                          In humans, where the drug is used oral, the most common side effects are nausea and diarrhea. But that may be unique to the oral formulation.

                            I used to work in one of the most prominent coag labs in the country back in the day. So I asked my vet about just how heparin-like this compound is.
                            His response was, "You probably wouldn't want administer it right before a surgery or to use it IA in a joint that is actively bleeding. But it has been around since the 1970's without a lot of problems (though not widely used in the US). It its strength as an anticoagulant are similar to aspirin."

                              A perfectly reasonable response. Much more so than the "it's perfectly safe" or "it can't hurt" attitudes one often sees (even on this thread) when this drug is discussed. I've gotten quite different responses from different vets to the same question, ranging from "we have no idea" to "I would consider it like a small dose of heparin" to "don't worry about it" to "I wouldn't use it in a horse with any recent surgery".

                              Aspirin is potent stuff.

                              Many people are wondering about the possibility of drugs in this class having anything to do with the occasional bleeding (EIPH among other things) equine fatalities that happen in eventing, racing, and other high-intensity horse sports. It's still too soon to say, of course, and I continue to defend these drugs wherever speculation gets crazy.

                              But ALL DRUGS should be treated with respect. There are NO "perfectly safe" ones.

                                I appreciate the distinction between Risks and Side Effects. Same for respecting drugs. I'm good with taking info and caution from vets. But I'm also willing to experiment a little more broadly with this old horse of mine. Worthless or not, I don't want to create a "he's bleeding to death"type crisis. That would be a PITA for all involved.

                                I appreciate the thread. Thanks, you guys.

                                  I get it from Wedgewood. Same price as an above post, $109./50mL vial.

                                  I had my 13 year old on Adequan last year with no discernible improvement. A very obvious improvement with the Pentosan.

                                  I have my two older guys on it now. They are 20 and 21 with LONG histories of competing as Advanced CDE horses. The ol' buggers are spry as all get out this spring!

                                  My vet recommended a loading dose of 1xweek for four weeks and then once every 3-4 weeks or as needed. My guys are all about 1400 lbs. and he told me to give them 10cc.

                                  I am quite happy with the results.

                                    And I have yet ANOTHER student whose vet will NOT prescribe it (for her older mare to make her more comfortable) nor are they willing to write a script for it. Argh!

                                    And Adequan IS on back order, so is not an option...

                                    Very, very frustrating. And yes, I think we--the general *we* of responsible horse owners--are well aware that there are "some risks" associated with any drug. The student who took her horse to Morven for a workup was prescribed a course of Bute for 2 weeks (as an anti-inflammatory--if it works, the horse and the owners can avoid doing an expensive bone scan for a MILD lameness.) I asked the vet whether the mare should also be on something "stomach buffering" during this course of Bute, and he said "no, not if her routine isn't changed and she gets plenty of forage" (she is out 24/7 on pasture.)

                                    So there are ALWAYS potential side effect to be considered, but if the benefits outweigh the side effects, isn't it *usually* worth taking that small risk?

                                    How many equine fatalities happen at BN/N level from bleeding out--as a result of (any) medication?

                                    I'm just cranky because this is the third student of mine, who despite a reasonable need, has been unable to get Pentosan for their horse from the local vet. How is it that Morven Park (and my own vets, and other student's vets) have no problem with this?
