Manufacturer: Pfizer Animal Health Registered Name Dectomax Injectable Endectocide Composition Doramectin 10 mg/mL; nonirritant oil base. Actions Doramectin is a persistent, broad spectrum, macrocyclic lactone which produces paralysis in exposed parasites, which in turn leads to expulsion of the parasite from the host animal. Doramectin acts by binding to nematode and arthropod glutamate-gated receptors, which are closely associated with GABA-gated sites, resulting in the activation of chloride ion channels and subsequent neuromuscular blockade. Indications Cattle. Control of the following parasites: small brown stomach worm (Ostertagia ostertagi) including inhibited larvae, barber's pole worm (Haemonchus placei), stomach hair worm (Trichostrongylus axei), black scour worm (T. colubriformis), T. longispicularis,* small intestinal worm (Cooperia oncophora), C. punctata, hookworm (Bunostomum phlebotomum),* nodule worm (Oesophagostomum radiatum), roundworm (Toxocara vitulorum)* and lungworm (Dictyocaulus viviparus). * = adults only.
