The drug dose within the figure of ten % is arbitrary: as the actual dose itself plays just a insignificant purpose inside the remaining drug influence, any compact dose will result in roughly exactly the same reaction so long as the body recognizes the drug. Most of the time, when there exists tolerance to some compound, the result of a small dose is limited to triggering the compensatory response, leading to outcomes reverse to the normal drug result.
These types can be utilized to assist Assume by equally scientific and logistical issues connected to integrating the precision dosing of the drug into follow. PK, pharmacokinetic; PK/PD, pharmacokinetic/pharmacodynamic.
