Medications Flashcards
chemical name
identifies drug’s atomic and molecular structure
what nomenclature is ibuprofen
generic
generic name
assigned by the manufacturer that first develops the drug
official name
name by which the drug is identified in official publications United States Pharmacopeia (USP) and National Formulary (NF) (typically generic name)
trade name

what nomenclature is advil and motrin
trade name
examples of oral meds
Capsule, pill, tablet, extended release, elixir, suspension, syrup
examples of topical meds
Liniment, lotion, ointment, suppository, transdermal patch
drug classifications
Classified by effect on body system; chemical composition; clinical indication or therapeutic action (2 primary classifications)
pharmaceutical class
Refers to the mechanism of action (MOA), physiologic effect (PE), and chemical structure (CS) of the drug (attacks bacteria by…)
therapeutic class
Refers to the clinical indication (why you’re using it) for the drug or therapeutic action (e.g., analgesic, antibiotic, or antihypertensive).
pharmacokinetics
effect of body on drug
absorption
drug moves from site of administration into bloodstream
distribution
drug transported in body fluid (typically bloodstream) to site of action: tissue/organ
metabolism
chemical conversion of drug in the body into water. Soluble compound of metabolites that can be excreted
excretion
drug molecules removed from site of action and eliminated from body
Factors Affecting Absorption of Medications
Route of administration
Lipid solubility
pH
Blood flow
Local conditions at the site of administration
Drug dosage
pharmacodynamics
the process by which drugs alter cell physiology and affect the body.
(how the drug affects the body)
Drugs turn on, turn off, promote, or block responses that are part of the body’s processes.
Drug–receptor interaction occurs when the drug interacts with one or more cellular structures to alter cell function.
Drugs may also combine with other molecules in the body to achieve their effect.
Other drugs act on the cell membrane or alter the cellular environment to achieve their effect.
drug-receptor interaction
occurs when the drug interacts with one or more cellular structures to alter cell function
palliative effects
treats symptoms of disease but not disease itself
supportive effects
supporting integrity of body function until another drug is effective
substitute effects
replace body fluids or chemical chemotherapeutic effects-destroy disease-producing organisms
restorative effects
restore to optimal health
examples adverse drug effects
Allergic effects: anaphylactic reaction
Drug tolerance
Toxic effect
Idiosyncratic effect
Drug interactions: antagonistic and synergistic effects
examples of allergic effects
hives, itching, inflammation of nose and sinuses, sudden restriction of bronchioles
drug tolerance
building up tolerance; decreased repsonse requires more drug for the same effect
toxic effect
too much drug causes damage to organs or tissues
idiosyncratic effect
abnormal response (unpredictable) ex. Benadryl making some children hyper
drug ineractions
antagonist and synergistic effects; effect decreased or increased ex. warfarin- vitamin k antagonist, asprin- bloodthinner
factors affecting drug action
Developmental considerations
Weight
Gender
Genetic and cultural factors
Psychological factors
Pathology
Environment
Timing of administration
drug dose and serum drug levels
therapeutic range, trough level, and half-life
therapeutic range
concentration of drug in the blood serum that produces the desired effect without causing toxicity
trough level
the point when the drug is at its lowest concentration, indicating the rate of elimination
half-life
amount of time it takes for 50% of blood concentration of a drug to be eliminated from the body
1.5 grams is how many mg
1500 mg
types of medication orders
standing order (routine order), prn, single or one-time order, stat order
standing order (routine order)
carried out until cancelled by another order
prn order
as needed, state why we are giving med
stat order
carried out immediately ex. Narcan and nitroglycerin
