Which medication is used to treat Enterobius vermicularis infection (Pinworm)?

Mebendazole is the specific medication used to treat Enterobius vermicularis infection, commonly known as pinworm infection. It works by inhibiting the microtubule formation in the pinworm, effectively disrupting their glucose uptake and ultimately leading to the death of the parasite. Mebendazole is preferred due to its efficacy and relatively safe profile in treating this common infection, especially in children.

Other medications mentioned are used for different types of parasitic infections. Praziquantel is primarily effective against flatworms, such as those causing schistosomiasis and tapeworm infections. Ivermectin is utilized for a range of conditions, including strongyloidiasis and onchocerciasis, but not for pinworms. Metronidazole is an antibiotic and antiparasitic that is effective against anaerobic bacteria and protozoa, but it is not effective against Enterobius vermicularis. Therefore, mebendazole stands out as the treatment of choice for pinworm infections.
