effect is the: - onset of action

of effect (response) produced by a given drug concentration (dose)
Shows the relationship between the dosage/concentration and the effect of the drug
concentration
Therapeutic window (range) - The range of plasma drug concentration with high
probability of therapeutic response
Provides a fixed comparison for drug safety
What is a narrow therapeutic window? - A drug that has little difference between
therapeutic and toxic doses
