This paper argues that there is no these clear relation and the dose-reaction curve presents only limited details about the drug influence. It is demonstrated that tolerance growth in the measurement of the dose-response curve may possibly induce major distortion in the curve and it truly is argued the curve may well only be made use of to point the reaction to the main administration of what is posology the drug, before tolerance has developed.
It is argued, furthermore, that the dose-reaction curve should not be applied right after the first dose of the drug as being a curve can not Convey the dynamic action from the tolerance mechanism.
