Dose Effect Relationship Of Stimulation

The dose effect relationship of agonists is shown in Figure A, which shows that the drug concentration [D] mol/L is hyperbolic with effect E. If the ordinate is changed to the maximum reaction percentage and the abscissa is log [D], a left right symmetric S-shaped curve can be obtained, as shown in Figure B. If the ordinate is changed to the reciprocal of the effect percentage and the abscissa is changed to the reciprocal of the drug concentration, a straight line is obtained
