In humans, ivermectin has an elimination half-life of 12 to 36 hours following a single oral dosage. This signifies that it takes this length of time for the medicine's concentration in the bloodstream to drop by half. However, Ivermectin and its metabolites can linger in the bloodstream for many days, with some studies indicating that effective doses can last up to 80 hours.
The medication is predominantly processed in the liver and expelled in feces, with less than 1% removed via urine. Cytochrome P450 substantially metabolizes Ivermectin Pills, with CYP3A4 being the main isoform responsible for biotransformation. Some metabolites, such as M1 and M2, have prolonged elimination half-lives of around 55 hours and are still poisonous to mosquitos. The prolonged availability of ivermectin and its active metabolites in the system allows the medicine to exercise its antiparasitic effects over time, which is especially useful in treating diseases such as onchocerciasis and strongyloidiasis.
