Dose-Response Relationship


Evaluation of the dose-response relationship or the dose-effect relationship is important in pharmacology. One can change the dose of a drug and measure a response. The response can be any type of response (e.g., decrease in systolic blood pressure by a certain amount, death of animal, etc.).

Dose % Response
2 10
4 20
5 25
8 40
10 50
20 70
30 85
50 90

A sigmoid curve is obtained if the dose axis is logarithmic.
