Mode of Action
Avermectin and ivermectin have similar modes of action, as they both belong to the same class of drugs called macrocyclic lactones. They work by binding to specific receptors in the nervous system of parasites, causing paralysis and death.
Both avermectin and ivermectin target a neurotransmitter called gamma-aminobutyric acid (GABA). GABA is an inhibitory neurotransmitter that plays a role in regulating the activity of nerve cells. When avermectin or ivermectin binds to GABA receptors in parasites, it disrupts the normal function of the nervous system, leading to paralysis and eventually death.
In addition to targeting GABA receptors, avermectin and ivermectin also interact with glutamate-gated chloride channels in parasites. These channels are involved in the regulation of chloride ions, which are important for the normal functioning of nerve cells. By interfering with these channels, avermectin and ivermectin further disrupt the nervous system of parasites, leading to their paralysis and death.
Avermectin Mode of Action
Avermectin primarily acts as an agonist of GABA receptors in parasites. It enhances the binding of GABA to its receptors, leading to increased inhibitory signals and prolonged paralysis of parasites. Avermectin also interacts with glutamate-gated chloride channels, further enhancing the inhibitory effects on nerve cells.
Ivermectin Mode of Action
Ivermectin has a similar mode of action to avermectin, but it is more selective in its binding to GABA receptors. It binds to a specific subtype of GABA receptor called the GABA-gated chloride channel, which is mainly found in parasites. This selective binding allows ivermectin to effectively target parasites while having minimal impact on the GABA receptors in mammals.
|GABA Receptor Binding||Agonist||Selective Agonist|
|Glutamate-Gated Chloride Channel Interaction||Yes||Yes|
|Impact on Mammalian GABA Receptors||Minimal||Minimal|
In summary, avermectin and ivermectin have similar modes of action, targeting GABA receptors and glutamate-gated chloride channels in parasites. However, ivermectin is more selective in its binding to GABA receptors and has minimal impact on mammalian GABA receptors, making it a safer option for use in humans and animals.
