Introduction to Ivermectin
Ivermectin is a semi-synthetic derivative of avermectin, a natural product isolated from the bacteria Streptomyces avermitilis. It has been primarily used against parasitic diseases such as onchocerciasis (river blindness), lymphatic filariasis, and intestinal strongyloidiasis. Additionally, its antiviral and anti-inflammatory properties have sparked research into its potential use against viral infections and other diseases. The drug works by targeting invertebrate nerve and muscle cells, causing paralysis and death of the parasites.
Pharmacokinetics of Ivermectin
The pharmacokinetics of ivermectin involves its absorption, distribution, metabolism, and excretion. Oral administration is the most common route for ivermectin. After ingestion, ivermectin is absorbed in the gastrointestinal tract, with peak plasma concentrations typically reached within 4 hours. The drug is highly lipophilic, which contributes to its extensive distribution into tissues, including fat, liver, and lung. Ivermectin is metabolized in the liver by the cytochrome P450 enzyme system, primarily the CYP3A4 isoform, and its metabolites are excreted in the feces.
Factors Influencing Absorption
Several factors can influence the absorption of ivermectin, including:
The formulation of the drug, with different formulations potentially affecting the rate and extent of absorption.
