| Common Name | Avermectin B1a |
|---|
| Description | Avermectin B1a belongs to the class of organic compounds known as macrolides and analogues. These are organic compounds containing a lactone ring of at least twelve members. They show activity against a broad range of nematodes and arthropod parasites of domestic animals at dose rates of 300 microgram/kg or less. The avermectins are a series of macrocyclic lactone derivatives with potent anthelmintic properties. Avermectin B1a is an extremely weak basic (essentially neutral) compound (based on its pKa). Avermectin B1a is a potentially toxic compound. It has low solubility in water and extensive non-specific binding. It opens GABA-insensitive chloride channels, reducing membrane resistance and increasing conductance inward. A commonly used therapy in recent times has been based on oral or parenteral administration of avermectins, which are macrocyclic lactones produced by fermentation of various, carefully prepared laboratory broths using the soil micro-organism Streptomyces avermitilis. Unlike the macrolide or polyene antibiotics, they lack significant antibacterial or antifungal activity. Avermectin B1a is found in Streptomyces avermitilis. Avermectins cause irritation of skin and eyes, central nervous system depression (incoordination, tremors, lethargy, excitation, pupil dilation, coma), vomiting, convulsions and/or tremors, and respiratory failure at high doses. |
