(b) Additive effect---when two drugs work together to produce an effect a single drug would not produce alone
(c) Adverse Reaction--an undesirable response to a drug that may be either sudden or take days to occur
(d) Allergy--reaction to a medication that causes local and systemic symptoms
(e) Cross Tolerance--The resistance to the effect or effects of a drug as a result of tolerance previously developed to another drug having a similar pharmacologic action
(f) Cumulative Effect--Develops with repeated doses prior to the initial dose being metabolized/excreted by the body
(g) Dependence---Physical "need" or psychological "desire" for the medication
(h) Habituation--the emotional or psychological dependence on a drug after repeated use (i.e. narcotics or analgesics)

(j) Iatrogenic Reaction---An adverse effect, condition, or disorder that is unintentionally produced by the administration of a drug
(k) Idiosyncratic Reaction--An abnormal reaction that is unpredictable and unique to a specific patient rather than a group of patients
(l) Loading Dose--A single dose or accumulation of several closely repeated doses used to obtain the therapeutic level that achieves the desired effect
(m) Maintenance Dose---Additional doses of a medication, administered after the loading dose, added to keep the medication at the therapeutic level
(n) Potentiation--A combination reaction where one drug enhances the effect of the other (codeine and alcohol)
(o) Side Effect--A response to a drug that is not the desired effect but seems to occur in many patients (headache with NTG)
