What is the primary indication for Ivermectin?

• A. Ascariasis
• B. Strongyloidiasis and onchocerciasis
• C. Trichuriasis
• D. Toxocariasis

Answer: (B)

Ivermectin is primarily indicated for the treatment of Strongyloidiasis and onchocerciasis due to its specific action against the parasites that cause these diseases. Strongyloidiasis is caused by Strongyloides stercoralis, a roundworm, while onchocerciasis, also known as river blindness, is caused by Onchocerca volvulus. Ivermectin works by binding to certain channels in the parasite's nervous system and musculature, leading to paralysis and death of the organisms. The choice of B as the correct answer highlights Ivermectin’s targeted efficacy for these particular infections, which are significant public health concerns, especially in tropical regions. Its effectiveness against Onchocerca volvulus makes it an essential drug in mass treatment campaigns aimed at reducing the transmission of river blindness. In comparison, the other choices involve parasites that are typically treated with different anthelmintic agents. Ascariasis, caused by Ascaris lumbricoides, is more commonly treated with medications such as albendazole or mebendazole. Trichuriasis, caused by Trichuris trichiura, also responds well to those medications. Toxocariasis, resulting from Toxocara canis or T
