An adjuvant is a substance (pharmacological and/or immunological) that modifies the effect of other substances or medicines. Immunological adjuvants may be added to vaccines to boost the immune response. Adjuvant therapy or care is therapy that is given in addition to the main or initial therapy to maximise its effectiveness. For example, radiotherapy is commonly given as adjuvant treatment after surgery for breast or other cancers.

Advanced therapy medicinal products

Advanced therapy medicinal products (ATMP) are new medical products for human use based on genes (gene therapy), cells (cell therapy), or tissues (tissue engineering). They have huge potential and open the way for new treatments of a number of diseases or injuries, such as skin in burns victims, Alzheimer's, cancer, or muscular dystrophy.

Adverse Drug Reaction

A response to a medicinal product which is harmful and unintended. Response in this context means that a causal relationship between the medicinal product and an adverse event is at least a reasonable possibility.

Adapted from the Guideline on good pharmacovigilance practices (GVP) Annex I - Definitions (Rev 3) 2014.

Adverse event

Any untoward (not favourable) medical occurrence in a patient, or clinical trial participant receiving a medicine, and which does not necessarily have a causal relationship with this treatment.

Adverse events can therefore be: any unfavourable and unintended sign (e.g. an abnormal laboratory finding), symptom, or disease temporallyassociated with the use of a medicine, whether or not considered related to the medicine.

Adverse reaction

An adverse reaction, is any adverse event or experience related to a medicine for which a reasonable causal relationship with the medicine™s use is suspected. This is synonymous with adverse drug reaction (ADR).


In medical science it is the study of the causes of diseases and the factors underlying their spread.
