COMMENTS

E-MOX PRO oral paste for horses is a classic horse wormer with moxidectin, oxfendazole and praziquantel from BAYER. Moxidectin is effective against roundworms and bots, oxfendazole against roundworms and tapeworms, praziquantel against tapeworms.

Moxidectin is a macrocyclic lactone introduced in the market in the early 1990s (by AMERICAN CYANAMID → PFIZER → ZOETIS). It is moderately used in livestock and pets. It is effective against most species of roundworms that affect horses and against bots (Gasterophilus spp), but not against tapeworms. It is moderately used in livestock, horses and pets, not in agricuture.

Moxidectin 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 fenbendazolemebendazole, or pyrantel the treatment interval is usually 4 to 6 weeks.

Whereas in ruminants moxidectin administered at 400 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.).

Oxfendazole is a veteran benzimidazole introduced in the 1970s (by WELLCOME) that is moderately used in livestock and horses, rather scarcely in pets. 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 also ineffective against horse tapeworms (Anoplocephala spp). It is scarcely used in livestock, horses and pets.

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. 

Oxfendazole and praziquantel have no residual effect, i.e. they kill the parasites after administration but do not protect against reinfestation.

Many horse owners complain about the price of the oral pastes & gels for horses (with ivermectin or other macrocyclic lactones), compared with the much cheaper injectables for livestock with the same active ingredients, used at the same dose (200 mcg/kg). This is why off-label use of livestock ivermectin injectables in horses is very common worldwide, particularly in working horses of cattle and sheep ranches. The reason why injectables are mostly not approved for use on horses is apparently that, shortly after introduction, it was noticed that horses were more prone to develop severe clostridial infections at the injection site (due to contamination of the needles) and other undesired side effects than cattle or sheep. In addition, the pharmacokinetic behavior of ivermectin on horses is different than in ruminants. For these reasons oral pastes were developed for horses that do not show such side effects. However, in numerous countries (e.g. in Latin America) some ivermectin injectables for livestock are also approved for use on horses.
