The therapeutic effect of your drugs is dependent upon many factors like age, local weather, weight, sexual intercourse, etc.
The static illustration of the relationship between drug dose and drug outcome prompt via the dose-reaction curve cannot be reconciled Along with the dynamic responses from the organism to changes in drug dose characteristic on the mechanism of tolerance improvement. Unless tolerance to a certain drug develops quite slowly, tolerance improvement will distort the curve when the impact of different drug doses is decided in only one issue.
2As continues to be mentioned extensively in Peper 2004a, the detection of exogenous substances inside the mouth is central to the whole process of tolerance development. The effect of the readjustments of disturbed processes following a drug administration will take time, as most processes in your body have a relatively slow reaction. If the human body were to attend with counteracting the drug action right up until it gets data from procedures by themselves they happen to be disturbed, the tolerance system might be also late to suppress the disturbance properly.
