T<u>he voltage gated sodium channels in the nerves and skeletal muscles are blocked, action potential are not generated from these areas,Therefore potassium channels are permanently open leading to hyper polarization, and since sodium channels can not open, they remain in refractory state, this leads to muscular paralysis leading to impairments of respiratory and cardiac functions.</u>
Specifically the paralysis of the diaphragm muscles, lead to collapse of the lungs, preventing breathing,leading to suffocation and death.
This is an example of competitive inhibition;The introduction of cholinergic acetycholine neurotransmitter reverses the blockage of sodium channels
