about permethrin -synthetic pyrethroid antiparasitic pediculicide scabicide. -mechanism of action of permethrin -permethrin exerts its action by inhibiting sodium ion channel and delays depolarization. this will leads to (neuronal) paralysis of insects. -permethrin kills insects by strongly exciting their nervous systems. it makes the nervous system hypersensitive to stimuli from sense organs. instead of sending a single impulse in response to a stimulus permethrin-exposed nerves send a series of impulses. this excitation occurs because permethrin blocks the movement of sodium ions from outside to inside of the nerve cells. it is active against a broad range of pests including lice ticks fleas mites and other arthropods.
