Tailoring drug therapy with thought into the drug, get more info ailment state, and affected individual enhances the chance to attain efficacy and more info lower adverse outcomes.
The static illustration of the relationship amongst drug dose and drug result prompt because of the dose-response curve cannot be reconciled Using the dynamic responses of your organism to variations in drug dose characteristic in the system of tolerance enhancement. Except if tolerance to a particular drug develops pretty gradually, tolerance improvement will distort the curve when the outcome of different drug doses is determined in only one topic.
