Graded Dose-Response Curve
  • Graded dose-response curves (plotted directly (no log transform) often resemble a Michaelis-Menten curves in which substrate (x-axis) is plotted against reaction velocity (y-axis)

 

Factors that result in variation in drug responsiveness
  • Idiosyncratic drug response
  • Tachyphylactic response
  • Hypersensitivity response
  • Alteration in concentration of drug that reaches the receptor (pharmacokinetic effect)
  • Variation in endogenous receptor ligand concentration
  • Alteration in the number or function of receptors
