The exact influence of the drug on somebody depends upon the dynamic relation involving quite a few variables, specially the extent of tolerance, the dose expected through the organism and the particular drug dose. Simulations using a Earlier released mathematical product of drug tolerance exhibit that the impact of a dose more compact compared to the dose the organism has designed tolerance to is difficult to forecast and may be reverse to your action of the standard dose.
It was argued above that if the compensatory reaction exceeds the drug action, unfavorable reactions occur. This was demonstrated in Fig. four with a discount of the dose to fifty %. In the event the dose is lessened far more, the net consequence will be close to the compensatory reaction by itself, as is revealed in Fig.
