Fig. 1From: On the relationship between inhibition and receptor occupancy by nondepolarizing neuromuscular blocking drugsDiagram of the interactions between acetylcholine (A), NDNB (D), and the postsynaptic receptor (R). The complexes formed by binding of ACh and NDNB to AChR are represented by 3-letter symbols, where the first and last letters denote the first and second ligands occupying the sites 1 and 2, respectively. The state ARA* represents the activated AChRBack to article page
