Which drug is recognized as the prototype anthelmintic agent?

Mebendazole is recognized as the prototype anthelmintic agent due to its broad-spectrum efficacy against a variety of helminths (worms). It works primarily by inhibiting the synthesis of microtubules in the parasitic nematodes, effectively disrupting their metabolism and reproductive capabilities. Its well-documented mechanism of action and extensive clinical use across different types of worm infections, such as those caused by roundworms and hookworms, establish it as a reference point in the development of other anthelmintic drugs.

Additionally, Mebendazole has been widely studied and is often used as a benchmark for comparing the efficacy, safety, and tolerability of newer anthelmintic agents. This factor solidifies its status in pharmacological literature and practice as the standard against which other anthelmintics are measured.

While Pyrantel, Ivermectin, and Praziquantel are effective anthelmintics, each has specific indications and may not have the same broad applicability as Mebendazole. Pyrantel is primarily effective against specific roundworms and hookworms, while Ivermectin is more suited to certain types of parasitic infections, including those caused by arthropods. Praziquantel is
