c) extent of non-specific binding, pH differences, blood flow

A patient who develops extreme tolerance to a drug will show the following change on the Dose Response curve:
a) shift to the right b) shift to the left c) decreased max tissue response d) shift to the right, decreased max tissue response |
d) shift to the right, decreased max tissue response
Developing tolerance/desensitization to a drug would shift the curve to the right: i.e. ED50 is increased, and you need more drug to produce the same effect as before. Extreme tolerance would not only shift the curve to the right, but would also decrease the % maximum tissue response on the y-axis as well, because the drug loses efficacy AND potency when the patient develops extreme tolerance.
