Risk of resistance? YES
- Small strongyles (cyathostomes). Tolerance of small strongyles to macrocyclic lactones (e.g. ivermectin, moxidectin), manifested as a low but significant worm egg output after treatment (determined after fecal egg counts) is not yet widespread, but has been already reported in Europe (e.g. in the UK, Germany, Italy), the USA, and Brazil. Resistance of small strongyles to benzimidazoles (incl. oxibendazole) is widespread and frequent in Australia, USA, UK and Europe, Argentina, Chile, Uruguay, etc.
- Parascaris equorum: Cases of resistance to macrocyclic lactones (e.g. ivermectin, moxidectin) and to benzimidazoles have been reported as well (e.g. in the USA and Australia).
This means that if this product does not achieve the expected efficacy against the mentioned parasites, it may be due to resistance and not to incorrect use, which is usually the most frequent cause of product failure.
It is generally accepted that the use of mixtures of active ingredients with different modes of action against a given parasite can delay the appearance of resistance. But only if the concerned parasites are susceptible to all the actives in the mixture. If not, the mixture is likely to promote multi-resistant parasites, because the selection pressure against all actives remains in place. Mixtures such as this one may provide peace-of mind to those users that do not know the resistance status of worms in their property: at least one of the actives will work... This may be the case for a while. But the risk that some worm species become resistant to all components after a few years using the same or comparable mixtures is considerable. If it is not too late, a better alternative is to determine the resistance status in the property and to rotate among products (not mixtures) against which the worms have not yet developed resistance, stopping the use of those chemical classes that have already shown resistance problems.
Alternative chemical classes/active ingredients to prevent resistance of gastrointestinal roundworms through product rotation:
- Imidazothiazoles, mainly levamisole. Not approved for use in horses in many countries.
- Tetrahydropyrimidines, mainly pyrantel (limited spectrum of activity), but resistance cases have also been reported (e.g. Australia, USA, Brazil, Japan).
These alternative products may not be available in all countries, or may not be available as oral pastes or gels.

TRIUMPH Liquid for horses is a classic horse wormer from BOEHRINGER INGELHEIM (previously MERIAL) with ivermectin, oxibendazole and praziquantel. Ivermectin is effective against roundworms and bots, oxibendazole against roundworms too, praziquantel against tapeworms.
Ivermectin is a broad spectrum parasiticide with efficacy against internal parasites (mainly roundworms) and against external parasites as well (mainly mites, lice, grubs, etc). This is why it is called an endectocide (controls endoparasites and ectoparasites). Ivermectin was the first macrocyclic lactone discovered and introduced in the 1980s by MS&D AgVet (later MERIAL). It is the parasiticide for livestock and pets most widely used worldwide, with probably thousands of generic brands. Ivermectin is probably the best veterinary parasiticide ever developed, highly effective against roundworms and, depending on the delivery form and formulation, also against numerous external parasites (ticks, flies, lice, mites, etc.). As all macrocyclic lactones, ivermectin used alone is ineffective against tapeworms and flukes, regardless of the delivery form. It is massively used in livestock and horses, less in pets. Ist is also used as a human medicine, and against agricultural and household pests.
Ivermectin and other macrocyclic lactones have about two weeks residual effect on horses because they are stored in body fat and progressively released. This, together with the time that worms need to develop inside the horse after infection (pre-patent period) allows to space the treatment intervals to 10 to 12 weeks in year-round control programs in many regions. For other active ingredients that have no residual effect such as fenbendazole, oxibendazole, mebendazole, or pyrantel the treatment interval is usually 4 to 6 weeks.
Whereas in ruminants ivermectin administered at 200 mcg/kg controls a series of external parasites as well (mites, lice, etc.), such an indication is not approved in most countries in horses: external parasites have to be controlled with ectoparasiticides (e.g. pour-ons, sprays, etc.).
Oxibendazole is a veteran benzimidazole introduced in the 1970s (by SMITH KLINE → PFIZER→ ZOETIS) that is rather scarcely used in horses and ruminants. It is a broad-spectrum anthelmintic effective against roundworms in the gut and the lungs, but not against those in the skin. It is also ineffective against gastric bots (Gasterophilus spp) or whatever external parasites. At the recommended dose it is usually ineffective against horse tapeworms (Anoplocephala spp). It is scarcely used in horses and pets. Usage in ruminants, swine and poultry is marginal. It is not used in agriculture or against household pests.
Praziquantel is a veteran anthelmintic introduced in the 1970s (by BAYER). It is highly effective against tapeworms (in horses mainly Anoplocephala spp) but has no efficacy whatsoever against roundworms. It is the anthelmintic most vastly used against tapeworms in horses and pets, used in hundreds of brands. It is hardly used in livestock. It is not used in agriculture.
Oxibendazole and praziquantel have no residual effect, i.e. they kill the parasites after administration but do not protect against reinfestation.
