Vol.1-Ch.13 "Emergency Pharmocology" Flashcards
(159 cards)
Chemical name VS generic name VS official name VS brand name
- Chemical name: chemical composition and molecular structure
- Generic name: suggested by manufacturer
- Official name: listed in United States Pharmacopeia (USP)
- Brand name: manufacturer gives drug name (trade or proprietary name)
Schedule I type drug and examples:
High abuse potential; may lead to severe dependence; no accepted medical indications; used for research, analysis, or instruction only
Examples: Heroin, LSD, mescaline
Schedule II type drug and examples:
High abuse potential; may lead to severe dependence; accepted medical indications
Examples: Opium, cocaine, morphine, codeine, oxycodone, hydrocodone, methadone, secobarbital
Schedule III Type drug and examples:
Less abuse potential than Schedule I and II; may lead to moderate or low physical dependence or high psychological dependence; accepted medical indications
Example: Limited opioid amounts or combined with noncontrolled substances; acetaminophen with codeine, buprenorphine
Schedule IV type drug and examples:
Low abuse potential compared to Schedule III; limited psychological and/or physical dependence; accepted medical indications
Examples: Diazepam, lorazepam, phenobarbital
Schedule V type drug and examples:
Lower abuse potential compared to Schedule IV; may lead to limited physical or psychological dependence; accepted medical indications
Examples:Limited amounts of opioids; often for cough or diarrhea
4 phases of human drug studies
Human studies: four phases.
Phase 1: drug’s pharmacokinetics, toxicity, safe dose.
Phase 2: test on limited population.
Phase 3: refine therapeutic dose; collect data on side effects.
Phase 4: postmarketing analysis during conditional approval
Six Rights of Medication Administration
Six Rights of Medication Administration Right medication Right dose Right time Right route Right patient Right documentation
4 things to consider when treating a pregnant Pt?
Pregnant patients; treating two patients.
Drugs that affect mother affect fetus.
Changes in mother’s anatomy and physiology.
Potential for drugs to harm fetus
What is a Broselow tape used for?
Broselow tape: approximation for children of average height/weight ratio. Helps find drug dosages for kids
Newborn’s metabolic rates _____ than adult’s; which makes them at _____ risk for toxic interactions.
Newborn’s metabolic rates lower than adult’s; which makes them at higher risk for toxic interactions.
4 things to consider with geriatric Pts
Absorb oral medications slower.
Aging alters distribution of drugs.
Likely to be on multiple medications; multiple underlying disease processes.
Medication interactions can have severe impact
Pharmacokinetics VS pharmacodynamics
Pharmacokinetics: how drugs transported into and out of body.
Pharmacodynamics: drug effects once they reach target tissues.
Do drugs create new cell properties or modify/exploit existing cell properties?
Drugs do not confer new properties on cells or tissues; modify/exploit existing functions.
4 processes of pharmacokinetics?
Processes:
- absorption
- distribution
- biotransformation
- elimination.
Passive VS Active Transport?
- Active transport: use of energy to move a substance; achieved by breakdown of high-energy chemical bonds.
- Passive transport: movement of substance without use of energy.
Diffusion VS Osmosis VS Filtration
Diffusion: movement of solute in solution.
Osmosis: movement of solvent.
Filtration: movement of molecules across membrane down pressure gradient; area of high pressure to lower pressure.
If drug is not soluble in water than…?
If drug not soluble in water, it will have difficulty being absorbed.
Rate of drug absorption is directly related to _____?
Rate of absorption directly related to amount of surface area available for absorption.
Ionized drugs do not _____; most drugs do not fully ionize.
Ionized drugs do not absorb across membranes of cells; most drugs do not fully ionize.
A drugs concentration affects _____; _____ concentration, more rapidly the body will absorb them.
A drug’s concentration affects absorption; higher concentration, more rapidly the body will absorb them.
Loading dose is?
Loading dose: larger dose of same concentration of drug.
Bioavailability means?
Bioavailability: measure of amount of drug still active after it reaches target tissue.
Once drug enters bloodstream, it must _____
Distribution: once drug enters bloodstream, it must be distributed throughout body
