In a medicine that is administered periodically, the trough level should be measured just before the administration of the next dose in order to avoid overdosing. [3] A trough level is contrasted with a "peak level" (C max), which is the highest level of the medicine in the body, and the "average level", which is the mean level over time. It is ...
Peak-to-trough ratio in pharmacokinetics is the ratio of peak (C max) and trough (C min) levels of a drug over its dosing interval (τ) at steady state.. Peak-to-trough ratio (PTR), also known as peak-to-trough variation or peak-to-trough fluctuation, is a parameter in pharmacokinetics which is defined as the ratio of C max (peak) concentration and C min (trough) concentration over a dosing ...
C max is the maximum (or peak) serum concentration that a drug achieves in a specified compartment or test area of the body after the drug has been administered and before the administration of a second dose. [1] It is a standard measurement in pharmacokinetics.
Therapeutic drug monitoring (TDM) is a branch of clinical chemistry and clinical pharmacology that specializes in the measurement of medication levels in blood. Its main focus is on drugs with a narrow therapeutic range, i.e. drugs that can easily be under- or overdosed. [1]
The variation can be described as a periodic function, which in turn can be split into a DC component (the peak value) [a] and an AC component (peak minus trough). [42] The ratio of the AC component to the DC component, expressed as a percentage, is known as the (peripheral) perfusion index (Pi) for a pulse, and typically has a range of 0.02% ...
That immediately gets the drug's concentration in the body up to the therapeutically-useful level. First day: 1000 mg; the body clears 100 mg, leaving 900 mg. On the second day, the patient takes 100 mg, bringing the level back to 1000 mg; the body clears 100 mg overnight, still leaving 900 mg, and so forth.

[1] [2] In the UK, they include "Bay Nursing", "Arm's Length Nursing" and "1:1 Nursing". The latter is also called "Specialling Nursing". They represent controlling the care from one station to an area -where includes a number of patients- by a nurse, 2 or 3 patients available to a nurse, or only one patient by a nurse respectively.
