The distortion with the curve for website the duration of the increase in dose is important. The total implication of the influence of tolerance growth, nonetheless, becomes apparent in the course of the reduce in drug dose in the event the lower in drug action leads to the compensatory reaction to become dominant and the overall drug effect to show negative.4 The dose-reaction curve is normally calculated by escalating the dose, in which situation no these types of reactions are produced.
