|
The ability of a drug to activate a receptor after binding
(not measured, but inferred) |
Intrinsic activity
|
|
|
A percent of the maximal response induced by a drug when 100% of the receptors are bound by that drug.
(measurable) |
Pharmalogical efficacy
|
|
|
The concentration of a drug required to give 50% of the maximal response
|
Pharmalogical potency
|
|
|
If drug A has more affinity for receptor than drug B, which has better efficacy?
|
Cannot be determined.
|
|
|
Measure of concentration required to induce a response of a particular intensity
|
Agonist potency
|
|
|
If drug A has the same efficacy as drug B, then both have same potency?
|
True, for drugs with the same efficacy, affinity predicts potency.
|
|
|
The ability of an antagonist to reduce the agonist induced response.
Measured as IC 50 |
Antagonist potency
