Dispensing III Flashcards
Response to a drug which is noxious and unintended and which occurs at doses normally used in man for prophylaxis, diagnosis, or therapy of disease or for the modification of physiologic function
ADVERSE DRUG REACTION
Asians and Eskimos
(Fast or Slow Acetylators)
Fast
Caucasians and Egyptians
(Fast or Slow Acetylators)
Slow
Most common type of ADR
AUGMENTED
Dose Dependent
Predictable
Common
Reproducible
TYPE A: AUGMENTED
most severe type of ADR
TYPE B: BIZZARE
-Not dose related
-Unpredictable
-Rare
-Unknown mechanism -Serious and fatal
TYPE B: BIZZARE
a disease that causes a fast rise in body temperature, resulting to severe muscle contraction and muscle breakdown
Malignant Hyperthermia
is due to hemolysis or abnormal breakdownof RBC
Hemolytic Anemia
is a immune-mediated
hypersensitivity complex involving the skin and mucous membrane; loss of up to 10% of outer layer of skin or necrolysis
Steven Johnsons Syndrome
genetically determined rxns or unsual effects
Idiosyncratic
related to immune responses to environmental antigens, resulting to symptomatic rxns
Hypersensitivity rxn
Allergic reaction that is provoke by reexposure to specific type of antigen or allergen (pollen)
TYPE 1: ANAPHYLACTIC/IMMEDIATE
- The antibodies produced bind to antigen on the patient’s own cell surfaces (leukocytes and erythrocytes) that will produce
compliment-mediated lysis
TYPE 2: CYTOTOXIC
- Leads to small immune complexes, which are not effectively
cleared, causing tissue damage and inflammation
TYPE 3: IMMUNE COMPLEX
A reaction that takes 2 to 3 days to developed
TYPE 4: DELAYED OR CELL MEDIATED
acute generalized reactions that occur when a previously sensitized person reexposed to a particle antigen
Anaphylactic reaction
Clinical manifestations of this reaction include hemolytic anemia, thrombocytopenia, and granulocytopenia
CYTOTOXIC REACTIONS
- Reaction result from the formation of antibody complexes in serum, which often deposit in blood vessel walls, resulting in activation of complement and endothelial cell injury
TYPE 3: IMMUNE COMPLEX
Dose Related
Time Dependent
Duration (↑) = Risk (↑)
TYPE C: CONTINOUS
person takes the drug compulsively
Addiction
craving and compulsive drug seeking behavior (body)
Physical Dependence
abstinence from drug produces physiological symptoms (mind)
Psychological Dependence
- reduced effect with repeated used of thedrug;decreased in physiological response to the susbtancewiththecontinuous use of the same dose
