Graded Dose-Response Curve

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
