Basic Pharmacology Flashcards
Why Are drugs prescribed?
-promote healing
-cure disease
-control or slow the progress of disease
-prevent disease
-decrease risk of complications
-Increase function and comfort
-provide replacement therapy
-Reduce excessive activity in the body
Pharmacodynamics
the study of the biochemical and physiologic effects of drugs.
(drug induced responses)
Pharmacokinetics
branch of pharmacology dedicated to determining the fate of substances administered to a living organism.
drug amounts at different sites after
administration
Pharmacotherapeutics
the application of pharmacological information together with the knowledge of the disease for its prevention, mitigation or cure
drug choice & application
Toxicology
Body’s responses to drugs
Pharmacy
the science or practice of the preparation and dispensing of medicinal drugs
Drugs are classified by their?
Effects
Generic Name
unique, official, simple name for a
specific drug
For example, acetaminophen
Trade/Propriety Name
Brand name
Ex: Tylenol
Chemical Name
Chemical components
Scheduled Drugs
Drugs requiring prescription due to their risk of harmful side effects and abuse
Indications
Approved for uses to treat
conditions for which the drug has been
proved to be effective
Off-label
uses for which the drug has
shown effectiveness but is not the
approved use.
Contraindications
Circumstances under which a drug should
not be administered
Side effects
Mild, undesirable effects of a drug, even at
recommended dose
Adverse or toxic effects
Drug effects that are dangerous, cause
significant tissue damage, or are
life-threatening
Hypersensitivity
Allergic Reactions
Idiosyncratic
Unusual responses to a drug
Iatrogenic
Negative effect associated with administration of drug
Teratogenic
Harmful effect on fetus, developmental defects
Interactions
drug effect modified by combination
with another drug
Synergism
Effect of drug combination may be greater than the sum of
the effects of the individual drugs.
Antagonism
Combination greatly decreases the effect of each drug
Potentiation
One drug enhances the effect of a second drug.
