The distortion with the curve all through the increase in dose is significant. The total implication of the result of tolerance development, even so, results in being obvious in the decrease in drug dose once the lessen in drug action triggers the compensatory reaction to be dominant and the general drug outcome to turn unfavorable.four The dose-reaction curve will likely be calculated by increasing the dose, during which scenario no this sort of reactions are produced.

The influence of a certain dose of a certain drug on a person is hard to predict as it is dependent upon a number of really different parameters, including the magnitude of your here compensatory response, the level of tolerance, the subject’s point out of health as well as historical past of drug administrations.

1988; Peper 2004a). When the administration of the drug is ongoing but the dose is reduced, nonetheless, the compensatory system will keep responding on the moments once the drug is administered, as demonstrated in Figs 4 and ​and7.
