Final answer:
Praziquantel is an anti-helminthic drug that increases the permeability of cell membranes to calcium, causing paralysis and death of the parasite.
Step-by-step explanation:
The anti-helminthic drug that increases the permeability of cell membranes to calcium, causing paralysis, dislodgment, and death of the parasite is praziquantel. Praziquantel is particularly useful for the treatment of schistosomiasis, a parasitic disease caused by blood flukes from the Schistosoma genus. Its mode of action involves causing an influx of calcium into the worm, resulting in intense spasm and paralysis of the worm.
