Unusual and unexpected sensitivity or reaction to a drug or food.
A peculiar susceptibility to some foreign substance or physical agent.
A way of behaving which is particular to one person.
Characteristic or manner unique to an individual or group.
An unusual and unexpected sensitivity exhibited by an individual to a particular drug or food.
A generally unexpected, therefore unpredictable, abnormal reaction to a drug. Sometimes, prior knowledge of a person’s condition makes the risk clear; the abnormal sensitivity of patients with porphyrias to barbiturates is one example, and may prove fatal. Hereditary biochemical defects of red blood cells are responsible for many drug-induced haemolytic anaemias and for favism. It is likely that all those who have unpredictable ill-effects (as opposed to known side-effects) from a drug probably have a genetic disorder rendering them more liable to such problems.
Special characteristics by which persons differ from each other.
Within the context of this specific pathway, a flaw emerges, giving rise to an abnormality in its functioning.
A unique trait related to one’s body, mind, or disposition. It refers to an individual’s distinct constitution that causes them to respond differently than most to certain drugs or treatments. For example, someone who experiences dizziness and a skin rash after taking aspirin.
