Abamectin acts by binding selectively and with high affinity to glutamate-gated chloride channels in invertebrate nerve and muscle cells. This leads to hyperpolarisation of these cells, resulting in flaccid paralysis and death of the parasite.
Morantel is a depolarising neuromuscular blocking agent producing paralysis by causing muscle contraction.
A year round worming prevention and treatment program varies with climatic and stocking conditions, but, in general terms all horses should be wormed every 6 - 8 weeks, commencing at approximately 6 weeks of age. All horses newly introduced to a property should be wormed immediately on arrival, and kept away from regularly used paddocks or yards for several days in order to minimise environmental recontamination.
