For that reason, a lesser IV injectable dose of a drug is necessary compared to the oral dose to realize the exact same blood stages. The onset of action is fast in IV formulations, and there might be increased likelihood of drug toxicity within the IV route

Imprecise drug dosing in specific subpopulations as a result of regular, set dosing strategies or gaps in know-how carries greater challenges for potentiating adverse events on account of supratherapeutic or subtherapeutic concentrations (Watanabe et al., 2018).

2As has become mentioned extensively in Peper 2004a, the detection of exogenous substances from the mouth is central to the whole process of tolerance development. The outcome with the readjustments of disturbed processes after a drug administration can take time, as most processes in the body have a comparatively sluggish reaction. If the human body had been to wait with counteracting the drug action until it gets information from processes on their own they happen to be disturbed, the tolerance system can be far too late to suppress the disturbance proficiently.
