Unit 5: Terminology of a drug action
Cross Tolerance & Cross Dependence
if a person has developed a tolerance to a drug in a certain classification, that person is more likely to develop tolerance with another drug in that classification
in cross dependence, the withdrawal symptoms from one drug in a classification can be relieved by another drug
Potentiation
occurs when two drugs are taken together and one of them intensifies the action of the other
could be expressed by the formula a + b = B
Additive Effect
when two or more drugs are taken at the same time and the action of one plus the action of the other results in the desired maximum response
could be represented with 1 + 1 = 2
Antagonism
an action for which two drugs given together have an opposite effect on the body
could be expressed by 1+1=0
Hypersensitivity
common reactions: hives, itching, nausea to a shock in which the person can die
a person can use a drug for years without any adverse reaction and then become hypersensitive to it
occurs after the first time the person has been exposed to the drug, not the first time the drug is taken
Side Effects
is an effect of the drug other than the one for which it was administered
can cause serious problems: abnormal production of red blood cells/stomach bleeding from the consumption of too much aspirin
