Therefore a drug that has a higher affinity to a receptor has a lower '''K<sub>A</sub>''' value.

* The biological response of resulting from an agonist is proportional to the number of receptors occupied. The size of a response can be measured and plotted against the dose/concentration of the agonist. As the size of a response normally increasee in a non-linear manner (until the maximum is reached) the response is normally plotted against the log of the concentration.
