NSG 531 Advanced Pharmacology Exam 2 || Updated Questions & Verified Answers || Rush University Pharmacodynamics: what the drug does to the body What is an LDR curve? A log dose response curve, or a curve that describes the relationship bewteen the drug effect (Y axis) and the log of the dose (X axis). What is the difference between quantal and graded LDR curves? Graded: the effect of the drug falls on a scale (i.e. how many mmHG did the BP decline when plotted against an increasing log dose?)Quantal: the "response" is predefined (i.e. a SBP 130 mmHg) and data is plotted to show who was affected and who wasn't. an either/or situation. Potency The dose of a drug necessary to produce 50% of a drug's maximal effect (ED50). Sort of tells you "how much bang you get for your buck" in terms of solely dosage amount. If the maximal response to a new medication is a 50mmHg decline in SBP, what is the ED50 on a graded LDR curve? The dosage that will produce a 25mmHg declined in SBP.
