Abstract
There has been considerable scientific, corporate and policy interest in the more effective use of genetics in both drug development and delivery. Pharmacogenetics — the study of the relationship between an individual's genetic makeup and response to medicinal drugs — has attracted global interest, but will it live up to its promise? Looking beyond the hype that has accompanied much of the commentary in the area, the future of pharmacogenetics will depend on how competing interests and options are resolved.

Glossary
- ABACAVIR
-
An antiviral drug, used, in conjunction with other medicines, for the treatment of HIV.
- AGRANULOCYTOSIS
-
A condition in which there is an insufficient number of white blood cells called neutrophils or granulocytes. This can be caused by a failure of the bone marrow to make sufficient neutrophils or when white blood cells are destroyed faster than they can be produced. Affected people are susceptible to infections.
- BIOBANKS
-
Public or private tissue collections (derived from blood, DNA or other sources) comprising samples taken from specific disease groups or healthy populations. Their long-term purpose is to build biological banks that will provide new sources of (genetic) information about disease that have clinical value.
- CLOZAPINE
-
An antipsychotic drug that works by decreasing abnormal excitement in the brain, used primarily to treat patients with schizophrenia who either fail to respond to or are unable to take other antipsychotic treatments.
- DISPOSITION
-
Refers to all processes involved in the absorption, distribution metabolism and excretion of drugs in a living organism.
- INVESTIGATIONAL NEW DRUG APPLICATION
-
(IND). An application that a drug sponsor must submit to FDA before beginning tests of a new drug on humans. The IND contains the plan for the study and is supposed to give a complete picture of the drug, including its structural formula, animal test results, and manufacturing information.
- ISONIAZID
-
An antibacterial drug used to treat tuberculosis.
- NEW DRUG APPLICATION
-
An application requesting FDA approval to market a new drug for human use in interstate commerce. The application must contain, among other things, data from specific technical viewpoints for FDA review — including chemistry, pharmacology, medical, biopharmaceutics, statistics and, for anti-infectives, microbiology.
- PHARMACODYNAMIC CHARACTERISTICS
-
The characteristics of a drug that determine its biochemical and physiological effects and its mechanisms of action.
- PHARMACOVIGILANCE
-
The process of monitoring medicines to identify previously unrecognised adverse effects; assessing the risks and benefits of medicines in order to determine what action, information and subsequent monitoring, if any, is necessary to improve their safe use.
- THERAPEUTIC INDEX
-
The therapeutic index of a drug is the ratio of the toxic dose to the therapeutic (that is, effective) dose, often used as a measure of the relative safety of the drug for a particular treatment. PGx is more likely to be clinically useful where the therapeutic index is narrow (i.e. when there is a smaller amount of difference between toxic and efficacious doses).
- 'RESTRICTED MARKETING' TERMS
-
A drug may have such serious adverse effects that regulatory approval is given for use in a specific patient group only, for whom it can be used safely.
- THIOPURINES
-
A family of chemotherapeutics used to treat leukaemia, as well as arthritis and inflammatory bowel disease.
- WARFARIN
-
Used to prevent blood clots from forming or growing larger (anticoagulant). Typically used for patients with atrial fibrillation and those with a venous thromboembolism.
