Zimecterin Gold is a combination product containing ivermectin and praziquantel, formulated for use in horses [1]. Ivermectin is a broad-spectrum antiparasitic agent, while praziquantel is effective against tapeworms [1][2]. Zimecterin Gold is used to treat or control internal parasites in horses, including roundworms, pinworms, strongyles, and tapeworms [1].
What is the active ingredient in Zimecterin Gold?
The primary active ingredient in Zimecterin Gold is ivermectin, an anthelmintic drug that works by disrupting the nerve and muscle function of parasites, leading to their paralysis and death [1][3]. Praziquantel is also an active ingredient, specifically targeting tapeworms [1].
How does ivermectin work in horses?
Ivermectin kills parasites by increasing the permeability of their cell membranes to chloride ions. This influx of chloride ions causes hyperpolarization of the nerve and muscle cells, leading to paralysis and death of the parasite [3].
What parasites does Zimecterin Gold treat?
Zimecterin Gold is indicated for the treatment and control of a range of internal parasites in horses. These include:
* Large and small strongyles
* Pinworms
* Ascarids (roundworms)
* Hairworms
* Neck threadworms
* Bots
* Lungworms
* Intestinal threadworms
* It also treats tapeworms [1].
Are there any side effects of Zimecterin Gold?
When used as directed, Zimecterin Gold is generally considered safe for horses [1]. However, side effects can occur, though they are uncommon. These may include swelling and depression. Transient ataxia and colic have also been reported [1].
Can ivermectin be used alone in horses?
Ivermectin can be used as a standalone dewormer in horses. Many ivermectin-only products are available for the control of nematodes and arthropods. However, ivermectin alone does not treat tapeworms, which is why praziquantel is included in formulations like Zimecterin Gold for broader coverage [2][1].
What is the difference between Zimecterin Gold and other dewormers?
Zimecterin Gold offers a combination of ivermectin and praziquantel, providing broad-spectrum coverage against both internal nematodes and cestodes (tapeworms) [1]. Other dewormers might contain only ivermectin, or different combinations of active ingredients like pyrantel pamoate or moxidectin, targeting different ranges of parasites or offering different durations of action [2].
When do drug patents expire for ivermectin formulations?
Patent expiration dates for specific ivermectin formulations can vary significantly depending on the original patent, any subsequent patents on new uses or formulations, and the jurisdiction [4]. Information on the patent status and expiration for veterinary drugs like those in Zimecterin Gold can be found on resources like DrugPatentWatch.com [4].
