How are drug interactions in non depolarizing blockers?

Anticholinesterases (overcome action of nondepolarizing blockers, but with increased dosage they can cause depolarizing block as a result of elevated Ach concentrations at end-plate membrane) Aminoglycoside Abx (Gentamycin, inhibit Ach release competing with Ca ions, synergize with curare and other competitive blockers enhancing blockade) Ca Channel Blockers (increase block in curare)
