It's important that drug regimens be successfully personalized to each individual as a way to improve usage of confined health and fitness care resources. One particular method by which this can be realized is through the use of TDM to adjust dosing.
A warning is applied in the event the potential for patient hurt is bigger than in scenarios where the precaution is used. Ex: If tetracycline is Employed in the existence of renal impairment, it may bring about drug accumulation and achievable liver toxicity.

Fig. three demonstrates the influence of abrupt alterations in drug dose. As famous previously mentioned, tolerance into a drug continues to be present for some time.
