title: Failure of neostigmine to prevent tubocurarine neuromuscular block in the isolated arm.
abstract: Neostigmine failed to modify the development of neuromuscular block in the presence of a high local concentration of tubocurarine. Only when the concentration of tubocurarine was reduced, and a suitable concentration gradient established between the receptor area and the plasma, did neostigmine increase the rate of recovery from the action of non-depolarizing neuromuscular blocking agents.
