How Does IVERMECTIN Work?

It kills worms and arthropods by inhibiting transmissions between neurons.... Therefore, it paralyzes the invertebrate parasites! It is relatively safe and nontoxic for mammals and the environment. Broad spectrum.

Other Dewormer Facts

Other dewormers (eg. Benzimidol1es) work by disruption of the cell cytoskeleton and/or mitochondrial function (PANACUR; RINTAL; BENZELMIN; EQUIZOLE). Some are very toxic, worms have developed resistance to many of them.

STRONGID-T (a tetrahydropyrimidine) and PIPERAZINE (a heterocyclic drug) also works by blocking neuromuscular transmission. The spectrum is not as broad and the safety margin is not as high as IVERMECTIN, but resistance is rare.
