The effects of polymyxin B at the neuromuscular junction of the frog were studied by conventional electrophysiological and voltage clamp techniques. At a concentration of 2.5 μg/ml polymyxin B produced neuromuscular blockade in 10 to 15 min and endplate potentials (e.p.ps) could be recorded. Resting membrane potential was unaffected. The neuromuscular block was characterized by a depressed e.p.p. quantal content (28 ± 7), which was similar to that determined from endplates exposed to 13 mm magnesium (23 ± 3), and a low e.p.p. quantal size, which was similar to that determined from endplates exposed to 3 μm (+)‐tubocurarine. Polymyxin B (0.25 to 0.75 μg/ml) decreased mean miniature e.p.p. amplitude with little effect on frequency. At a conce...
