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