Interpretation & conclusions: Our report indicates that using the 300 μg/ml/kg dose of ivermectin increases the
mean survival period from 5 to 12 days. This suggests that ivermectin could be possibly used in the treatment of
trypanosomiasis. Further studies will be required to show whether proper treatment may entail a single dose, as
used in this study; an increased number of doses, or combinations with other drugs.
And there it comes Ivermectin
