Mod 2: Effects of Drugs and Drug Interactions Flashcards
(38 cards)
It is the therapeutic effect
of the drug
Desired response to drug
PRIMARY EFFECT
Side effects, adverse drug reactions, drug toxicity and drug allergy, teratogenic and carcinogenic effects
SECONDARY EFFECT
drugs combined with other
drugs and foods
DRUG INTERACTIONS
- is a response to a drug that is directly opposite the desired
therapeutic effect.
paradoxical response
- Side-effects
- Adverse drug reactions
- Drug toxicity
- Drug allergy
- Teratogenic and carcinogenic effects
SECONDARY EFFECT
secondary effects of drug therapy that can be predictable ranging from inconvenient,
severe or life threatening
Side-effects
are unintentional, unexpected reactions to drug therapy that occur at normal drug
dosages
-reactions are undesirable, could be mild to severe, must be reported and documented
Adverse drug reactions
- simple overdose with extended desired effect occurrence
primary adverse reactions
wide variety of effects in addition to the desired effect
secondary actions
secondary adverse effect
occurs when drug levels exceed the therapeutic range secondary to overdose (intentional or unintentional) or drug accumulation
Drug toxicity
-factors that influence drug toxicity
disease, genetics and age
The liver is where most drugs are metabolized, where oral drugs are absorbed and
passed directly that may lead to liver damage
Hepatotoxicity
gentamycin as a potent antibiotic is frequently associated with renal injury
Renal injury
occurs when an overdose of drug damages multiple body systems.
Poisoning
Occurs when the body forms antibodies to a particular drug causing an immune
response
Drug allergy
4 types of Drug allergy
anaphylactic reaction
Cytotoxic reaction
Serum sickness reaction
Delayed allergic reaction
antibody reaction at specific sites releasing histamine causing immediate reactions
anaphylactic reaction
secs.-min
antibodies in blood attack drug on cell site causing death of the cell manifesting over a few days
Cytotoxic reaction
—mins-hrs
antibodies circulate in blood depositing on blood vessels causing damage to tissue and occurs up to 1 week or more after exposure
Serum sickness reaction
– hrs-<1day
occurs several hours after exposure and antibodies are bound to specific white blood cells
Delayed allergic reaction
–1 day-several days
teratogen substances can cause developmental abnormalities
teratogenic effect
Teratogenic period
begins _____ after conception and after ____ may cause to either death of the embryo or minor cellular damage without congenital birth defects
2 weeks
drugs are potentially dangerous that chemical reactions occur altering both normal
and abnormal body tissues.
carcinogenic drug
Types of Drug interactions
Drug to Drug interaction
Drug to drug interactions and pharmacokinetics
Drug-Food Interaction
Drug-Laboratory Test Interactions
