Source of obtaining ivermectin
It is a semi-synthetic macrocyclic lactone drug. Semi- synthetic drug means a drug which neither completely natural nor completely man made ( artificially ). It is made by using chemicals and enzymes with natural materials and convert them into final product. It is obtained from a microbe called streptomycin avermitilis of actinomycete family. Ivermectin is a drug of choice for strongyloidiasis and onchocerciasis.
Mechanism of action
The first thing you must know that it is a chloride channel blocker. You know very well that there are many channels located on the surface of the cell membrane to transport the ions across the cell membrane means from outside to inside of the cell and vice versa. So ivermectin is the chloride channel blocker. It blocks the chloride channels and whenever it blocks the channel, it will leads to hyperpolarization which results the nerves and muscles paralysis. This paralysis further cause the death of the micro organism. The half life of ivermectin is about 16 hours. Means it becomes half of it’s initial dose within 16 hours in the body. Ivermectin is a microfilaricidal but not a macrofilaricidal.
