This group of drugs are derived from ''Streptomyces'' species and are coded as '''3-AV''' products. They are commonly known as '''avermectins''' and '''milbemycins'''. Drugs in use include; '''ivermectin, abamectin, doramectin, moxidectin, eprinomectin''' and '''selamectin'''.
==Activity==
* They have a wide spectrum of activity. They are '''endectocides'''; active against common [[nematodes]] at all developmental stages and against many [[arthropods]].
* They are inactive against trematodes, cestodes and adult filarial worms. Though are active against migrating heart worm larvae and are used as heartworm prophylactics in cats and dogs.
* Their mode of action is by opening invertebrate specific glutamate-gated chloride channels on the post-synaptic membranes. This results in '''flaccid paralysis''' of the parasite.
