Fig. 3 demonstrates that the large tumble in drug effect in response to your lessen in dose is accompanied by a rise in drug effect throughout subsequent drug administrations. The reduction in drug dose With this determine has actually been chosen to get a big Original reduction in drug impact. On the other hand, any reduction in dose just after tolerance has developed will probably be accompanied by an increase in drug effect right up until the organism has readjusted the magnitude on the compensatory response to correspond While using the action of the new drug dose. This gradual rise in drug influence may well clarify scenarios of sensitization, a phenomenon whereby the drug impact improves for the duration of recurring administrations (Robinson and Berridge 1993; Everitt and Wolf 2002).

An additive effectis made when the total pharmacological action of two or more drugs administered jointly is such as the sum in their pharmacological action.
