In the treatment of echinococcosis, which medication is often used?

In the treatment of echinococcosis, albendazole is often used due to its efficacy against the larval stages of Echinococcus species. Albendazole operates by inhibiting the polymerization of tubulin, which is crucial for the cellular structure and function of the parasite. This action effectively disrupts the metabolic processes of the Echinococcus larvae, leading to their death.

The other medications listed are not as effective for treating echinococcosis. Praziquantel is primarily used against cestodes and trematodes but is not the first choice for Echinococcus infections. Mebendazole is commonly used for treating intestinal nematode infections and has limited efficacy against echinococcosis. Levamisole is an immunomodulator that is not specifically an anthelmintic for this type of infection, thus making albendazole the most appropriate choice for this condition.
