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.
Even less safe are drugs such as digoxin, a cardiac glycoside; its therapeutic index is approximately 2:1. [12] Other examples of drugs with a narrow therapeutic range, which may require drug monitoring both to achieve therapeutic levels and to minimize toxicity, include dimercaprol, theophylline, warfarin and lithium carbonate.
The drug or other substance has a high potential for abuse. The drug or other substance has no currently accepted medical use in treatment in the United States. There is a lack of accepted safety for use of the drug or other substance under medical supervision. The complete list of Schedule I substances is as follows. [1]
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 ...
Finally, note that the benzodiazepine core is a privileged scaffold, which has been used to derive drugs with diverse activity that is not limited to the GABA A modulatory action of the classical benzodiazepines, [60] such as devazepide and tifluadom, however these have not been included in the list below. 2,3-benzodiazepines such as tofisopam ...
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] TDM aimed at improving patient care by individually adjusting the dose ...
At a practical level, a drug's bioavailability can be defined as the proportion of the drug that reaches the systemic circulation. From this perspective the intravenous administration of a drug provides the greatest possible bioavailability, and this method is considered to yield a bioavailability of 1 (or 100%). Bioavailability of other ...
Delta 9 THC is the parent compound. If a saliva sample is tested in a lab, the detection level can be as low as 0.5 ng/mL (up to 72 hours after intake). [24] Per National Institute on Drug Abuse saliva drug testing provides a reasonable alternative to other drug testing methods. [25]
