Therapeutic Action:

Ivermectin: It works by potentiating the neuronal inhibitory action of GABA on the ventral nervous system of nematodes. It prevents the transmission of the nervous stimulus causing flaccid paralysis of the parasites.

Praziquantel: Increases the flow of calcium through the parasite's integument causing its vacuolation and disintegration. It exposes parasitic antigens, activating the defense mechanisms of the host. It also alters the metabolism of cestodes, interfering with glucose uptake, lactate release, and glycogen and ATP levels.
