<prompt> The following antibiotic accentuates the neuromuscular blockade produced by pancuronium:StreptomycinErythromycinPenicillin GChloramphenicol  <response>: Aminoglycosides like streptomycin and gentamicin can accentuate the neuromuscular blockade produced by competitive blockers like pancuronium. Mechanism of neuromuscular blockade produced by aminoglycosides is the inhibition of presynaptic release of ACh.
