Fig. 5.

The isobolograms for combinations of (A) vecuronium and pancuronium, (B) of (+)-tubocurarine and cisatracurium, and (C) of metocurine and cisatracurium. Closed symbols indicate data points derived from full concentration response curves (as in Figs. 3 and 4). The solid lines isobolograms that fit the closed symbol data point. Open symbols indicate concentration pairs that lie on the isobologram and should produce a relative current (Rel Curr) of 0.1. The insets show the measured relative current produced by these additional concentration pairs. None of the additional pairs produced a relative current significantly different from 0.1.
