The story of ivermectin originated in 1974, when scientist Satoshi Omura discovered Streptomyces avermitilis, which later led to the isolation of an active compound, avermectin and finally, ivermectin . Ivermectin, which consists of two homologs (namely dihydro-avermectin B1b and dihydro-avermectin…
