milbemycin

milbemycin

(mil-be-mī'sin),
A macrocyclic lactone (macrolide) antiparasiticide used for prevention of heartworm caused by Dirofilaria immitis, treatment of Toxacara canis, Toxascaris leonina, Trichuris vulpis, and Ancylostoma caninum gastrointestinal (GI) parasites in heartworm-negative dogs; also has activity against ectoparasites such as Demodex sp.; in the avermectin family; derived from 5-didehydromilbemycin moiety from Streptomyces hygroscopicus subsp. aureolacrimosis; less toxic in Collies than ivermectin; given monthly orally. In cats, labeled for Dirofilaria immitis prevention, and treatment of GI parasites TOXACARA CATI and Ancylostoma tubaformae. Enhances gamma amino butyric acid release at the presynaptic membrane resulting in parasite paralysis and death. Not effective against flukes and tapeworms.

milbemycin

a macrolone lactone, derived from Streptomyces cyanogeneus, similar to the avermectins, effective as an anthelmintic and parasiticide. Milbemycin oxime is used for the prevention of heartworm in dogs and it has found a use in the treatment of generalized demodecosis.
