Ivermectin
A comprehensive pharmacokinetic-pharmacodynamic evaluation of the endectocide ivermectin has shown that mosquitocidal effects persist beyond the elimination of the predominant component of the parent compound. This opens up the possibility of either an unidentified active metabolite, or slower elimination of the more active minor component. In either case this has firmly put ivermectin in centre stage as a potential elimination tool. WHO has endorsed this and encouraged further research to identify the active principals - which is ongoing with the Department of Pharmacology.
