Praziquantel targets which type of parasite?

Explanation:
Praziquantel targets tapeworms primarily. It works by increasing the parasite’s cell membrane permeability to calcium, causing strong muscle contractions and paralysis, which damages the parasite’s tegument and leads to detachment from the intestinal wall. This damage exposes the parasite to the host’s immune system and results in death and expulsion. Tapeworms (cestodes) are highly susceptible, making praziquantel especially effective for treating tapeworm infections. It has little effect on roundworms (nematodes) or mites, and while it can affect some trematodes (flukes), its most reliable action is against tapeworms.
