Applied at the recommended dose volume of 1 mL/10 kg (22 lb) body weight, to achieve a dose level of 500 mcg eprinomectin/kg body weight, EpriGard Pour-On is indicated for the effective treatment and control of the following parasites. Gastrointestinal Roundworms Haemonchus placei (adults and L4) Ostertagia ostertagi (including inhibited L4) (adults and L4) Trichostrongylus axei (adults and L4) Trichostrongylus colubriformis (adults and L4) Trichostrongylus longispicularis (adults only) Cooperia oncophora (adults and L4) Cooperia punctata (adults and L4) Cooperia surnabada (adults and L4) Nematodirus helvetianus (adults and L4) Oesophagostomum radiatum (adults and L4) Bunostomum phlebotomum (adults and L4) Strongyloides papillosus (adults only) Trichuris spp. (adults only) Lungworms Dictyocaulus viviparus (adults and L4) Cattle Grubs (all parasitic stages) Hypoderma lineatum, Hypoderma bovis Lice Damalinia bovis, Linognathus vituli, Haematopinus   eurysternus, Solenopotes capillatus Mange Mites Chorioptes bovis, Sarcoptes scabiei Horn Flies Haematobia irritans EpriGard (eprinomectin) Pour-On for Beef and Dairy Cattle has been proved to effectively control infections and to protect cattle from re-infection with Dictyocaulus viviparus for 21 days after treatment and Haematobia irritans for 7 days after treatment. Varying weather conditions, including rainfall, do not affect the efficacy of EpriGard Pour-On. For best results EpriGard Pour-On should be applied to all cattle in the herd. Cattle introduced to the herd later should be treated prior to introduction. Consult your veterinarian or an entomologist for the most effective timing of applications for the control of external parasites. Chorioptic Mange: In clinical studies evaluating the efficacy of eprinomectin Pour-On against chorioptic mange mites, mites were not recovered from skin scrapings taken 8 weeks after treatment; however, chronic skin lesions were still present on some animals. Horn flies: For optimal control of horn flies, as EpriGard Pour-On provides 7 days of persistent activity against horn flies, the product should be used as part of an integrated control program utilizing other control methods to provide extended control.

INTRODUCTION
EpriGard Pour-On delivers effective internal and external parasite
control in one
application. EpriGard Pour-On contains eprinomectin, a unique
avermectin. Its broad-
spectrum efficacy in a weatherproof formulation, margin of safety,
zero slaughter
withdrawal and zero milk discard, make it a convenient product for
parasite control in
beef and dairy cattle, including lactating dairy cattle.
MODE OF ACTION
Eprinomectin is a member of the macrocyclic lactone class of
endectocides which have a
unique mode of action. Compounds of the class bind selectively and
with high affinity to
glutamate-gated chloride ion channels which occur in invertebrate
nerve and muscle
cells.
This leads to an increase in the permeability of the cell membrane to
chloride ions with
hyperpolarization of the nerve or muscle cell, resulting in paralysis
and death of the
parasite. Compounds of this class may also interact with other
ligand-gated chloride
channels, such as those gated by the neurotransmitter
gamma-aminobutyric acid
(GABA).
The margin of safety for compounds of this class is attributable to
the fact that
mammals do not have glutamate-gated chloride channels, the macrocyclic
lactones have
a low affinity for other mammalian ligand-gated chloride channels and
they do not readily
cross the blood-brain barrier.
INDICATIONS
EpriGard (eprinomectin) Pour-On is indicated for the treatment and
control of
gastrointestinal roundworms (including inhibited _Ostertagia
ostertagi_), lungworms,
grubs, sucking and biting lice, chorioptic and sarcoptic mange mites,
and horn flies in
beef and dairy cattle of all ages, including lactating dairy cattle.
