  Therapeutic index
The therapeutic index of a medication is a comparison of the amount that causes the therapeutic effect to the amount that causes toxic effects.
Drugs with a wider therapeutic index, such as diethyl ether and especially cannabis, require less expert intervention in their use, and tend to be less accepted in developed countries.
Overdose is also related to the therapeutic index as well since with a narrow therapeutic index the transition into toxicity occurs more easily.

 Therapeutic index - Wikipedia, the free encyclopedia
The therapeutic index (also known as therapeutic ratio or margin of safety), is a comparison of the amount of a therapeutic agent that causes the therapeutic effect to the amount that causes toxic effects.
A commonly used measure of therapeutic index is the lethal dose of a drug for 50% of the population (LD
Examples of drugs with a narrow therapeutic range, that may require drug monitoring both to achieve therapeutic levels and minimise toxicity, include: digoxin, dimercaprol, theophylline, and lithium carbonate.

 Therapeutic Drug Monitoring - Auburn University - College of Veterinary Medicine
Therapeutic drug monitoring is indicated in clinical situations in which an expected therapeutic effect of a drug has not been observed, or in cases where drug toxicity related to high toxic PDC is suspected.
In addition, TDM can be used to establish whether or not optimum therapeutic drug concentrations have been achieved for drugs characterized by a response that is difficult to detect or in which the manifestations of disease are life threatening and the trial and error approach to modification of dosing regimen is unacceptable.
Therapeutic drug monitoring is useful in monitoring treatment with these drugs in order to assure that therapeutic concentrations are achieved and toxic concentrations avoided during each dosing interval.

 Pharmacokinetics: Therapeutic Index
The ratio of the drug dose which produces an undesired effect to the dose which causes the desired effects is a therapeutic index and indicates the selectivity of the drug and consequently its usability.
It should be noted that a single drug can have many therapeutic indices, one for each of its undesirable effects relative to a desired drug action, and one for each of its desired effects if the drug has more than one action.
Both the positioning and the slope of the cumulative frequency distribution curves for the desired effect, for the side effects, toxic effects and lethal effect are important indicators of the safety of the drug and our ability to use the drug successfully.

 Cecil Textbook of Medicine : />
The therapeutic window is shown as the range of therapeutically effective concentrations, which includes most of the efficacy curve and less than 10% of the toxicity curve.
The therapeutic index is calculated by dividing the 50% value on the toxicity curve by the 50% value on the efficacy curve.
Table 27-1, in addition to providing useful pharmacokinetic data, lists therapeutic ranges for several commonly used drugs for which measuring the drug concentration and knowing the therapeutic range may be useful in clinical management.

Therapeutic window is the range of serum concentrations within which the probability of efficacy is high, and the probability of toxicity is low.
Narrow therapeutic index - drugs where serum concentrations that produce toxicity are slightly above the range which produces efficacy, sometimes toxicity can occur within the therapeutic range.
Drugs with a narrow therapeutic index require therapeutic drug monitoring to maximize efficacy and minimize toxicity.

A prescription for a narrow therapeutic index drug may be refilled only by using the same drug product by the same manufacturer that the pharmacist last dispensed under the prescription, unless otherwise agreed to by the prescribing physician.
The term "narrow therapeutic index drug" is not defined in the Texas Pharmacy Act or elsewhere in the laws of this state.
In short, the Board has determined that there are no "narrow therapeutic index drugs" for which special rules should apply with respect to the use of generic substitutions in refills.

 Therapeutic Equivalence of Generic Drugs
FDA wishes to comment on the issue of interchanging any brand-name drug with a therapeutically equivalent generic drug and requests that you inform your association's members of this information.
These drugs may sometimes be described in FDA approved drug labeling as narrow therapeutic range drugs.
It is not necessary for the health care provider to approach any one therapeutic class of drug products differently from any other class, when there has been a determination of therapeutic equivalence by FDA for the drug products under consideration.

 Bioline International Official Site (site up-dated regularly)
The finding is of special significance since substitution of one brand of theophylline, a drug with a narrow therapeutic index, with another brand may result in sub-therapeutic response in patients.
Theophylline being a narrow therapeutic index drug, it is legally incumbent on the manufacturers to ensure the quality of the marketed formulations, since a small change in the systemic concentrations may lead to a marked change in the pharmacodynamic response, with undesirable therapeutic consequences.
Thus, asthmatic patients whose therapeutic response to theophylline, in approved doses, is sub-optimal may not necessarily be drug-resistant.

The concept of concentration control has not been critically explored because most available drugs have a high therapeutic index, where the difference between maximally tolerated concentration (MTI) and minimum effective concentration (MEC) is large.
However when the therapeutic index (TI) is narrow, the concentration control concept is utilized.
This is the case in the use of aminoglycosides, antiepileptic drugs and cancer chemotherapy.
