Uncoupling of oxidative phosphorylation in skeletal muscle-the signs and symptoms of the patient indicate that he is suffering from salicylate overdose toxicity.even if salicylates have an antipyretic action they can cause hyperthermia when given in too high doses. -this seems mainly due to the uncoupling of oxidative phosphorylation in skeletal muscle, that is oxidation proceeds without phosphorylation so producing heat. this action is quite similar to that produced by dinitrophenol.a, b, c, e) all these are actions of salicylates but have nothing to do with salicylate inducedhyperthermia.
