What Is Drug Response

18.1 Overview. Drug response or adverse effect is the net effect of multiple factors: age, organ function, concomitant therapy, drug interactions, and disease.

What are the types of drug response?

Adverse drug reactions are classified into six types (with mnemonics): dose-related (Augmented), non-dose-related (Bizarre), dose-related and time-related (Chronic), time-related (Delayed), withdrawal (End of use), and failure of therapy (Failure).

How is drug response measured?

The metrics usually used to parameterize drug response (IC50, Emax, or AUC) are based on assessing the cell count of a treated condition relative to an untreated control.
