Tick praziquantel mechanism of action: a) Blocking acetylcholine transmission at the myoneural junction and paralysis of helminthes b) Inhibiting microtubule synthesis in helminthes and irreversible impairment of glucose uptake c) Increasing cell membrane permeability for calcium, resulting in paralysis, dislodgement and death of helminthes d) Inhibiting oxidative phosphorylation in some species of helminthes
