NCIt definition : A macrocyclic lactone derived from Streptomyces cyanogriseus with antiparasitic activity.
Upon administration, moxidectin may bind to glutamate-gated chloride channels (GluCl),
gamma-aminobutyric acid (GABA) receptors and/or ATP-binding cassette (ABC) transporters
expressed on nematode neurons and pharyngeal muscle cells. As a result, neurons or
muscle cells remain at either hyperpolarization or depolarization state, thereby resulting
in muscle paralysis. Moxidectin reduces the motility and fertility of the parasite
and its excretion of immunomodulatory proteins, and inhibits the release of microfilariae.;
