What is Metaflumizone?

The Uses of Metaflumizone

Metaflumizone is a semicarbazone insecticide that works by blocking sodium channel in target insects resulting in paralyzation associated with blocking nerve activity. Metaflumizone is useful as a hea rtworm control treatment.

Veterinary Drugs and Treatments

Metaflumizone is a new insecticide used for the treatment and control of fleas on dogs and cats. It blocks the influx of sodium required to propagate a nerve impulse along the axon and dendrite of the neuron causing a reduction in feeding, loss of coordination, paralysis and death of the flea.
