It is common for international and UK Life Science companies to use specific medical terms and acronyms. For those in this industry some terms are second nature, but for others they are not and so can create confusion! Barlow Robbins has produced a glossary of terms in order to help navigate some of the most commonly used terms.
We hope that this new edition (version 2) of our Life Sciences glossary is of use and welcome suggestions for additions at any time by contacting Tim Matthews, Life Science, Corporate and Commercial team.
- A - C
Adverse Drug Reaction or ADR
In clinical trials: all adverse or unusual noxious and unintended responses to a medicinal product related to any dose or doses so that a causal relationship between a medicinal product and an adverse reaction is at least a reasonable possibility so that the relationship cannot be ruled out.
Regarding marketed medicinal products: a response to a drug which is noxious and unintended and which occurs at usual doses normally used for therapy of diseases, for modification of physiological function or diagnosis.
Adverse Event or AEAny untoward medical occurrence in a patient or clinical investigation subject administered a pharmaceutical product. An AE can therefore be any unfavourable and unintended sign (including an abnormal laboratory finding), symptom, or disease temporally associated with the use of a medicinal (or investigational) product, whether or not related to the medicinal (or investigational) product.
