BOVIMEC Pour-On effectively controls all stages of cattle grubs. However, proper timing of treatment
is important. For the most effective results, cattle should be treated as soon as possible after the end
of the heel fly (warble fly) season. While this is not peculiar to ivermectin, destruction of Hypoderma

Ivermectin is a member of the macrocylic lactone class of endectocides which have a qunique
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 mus-
cle, resulting in paralysis and death of the parisite. Compounds of this class may also interact with
other ligand-gated chloride channels, such as those gated by the neurotransmitter gamma-
aminobutyric acid or GABA. The margin of safety for compounds of this class is attributable to the
fact that mammals do not have the glutamate-gated chloride channel, the macrocyclic lactonas
have a low affinity for mammalian ligand-gated chlorid channel and they do not readily cross the
Studies conducted in the U.S.A. have demonstrated the safety margin for ivermectin. Based on
plasma levels, the topically applied formulation is expected to be at least as well tolerated by
breeding animals as is the subcutaneous formulation which had no effect on breeding performance.
