Week 5 basic Pharm Flashcards
Drug:
Medication:
Foreign to body
for medicinal purposes
Chemical name:
Generic name:
Official name:
Brand name:
=least common EX 7-chlor-1-3dihydro….
=directly manufactured EX Ibuprofen (captialized)
=name registered listed with USP EX Diazepam, USP
=name by company followed by trademark/propriety EX motrin advil
Medication profile components:
Names, class, Pharmacodynamics, Pharmacokinetics, contra/indications, admin/ routes, dose & how carried, adverse effects (unintended effects, untoward effects), special considerations,
Where meds come from:
plants, animals, minerals, synthetic (lab-made),
Nightshade plant
Atropine
Foxglove plant
Digoxin
Harrison narcotic act (1914)
“Hell Nah” aimed a controlling the importation, manufacture, & sale of opium & coca plant & its derivatives
FDA & cosmetic act (1938)
truth-in-labeling cause→ state whether the prep contains habit-forming drugs and its%
Durham-Humphrey amendments (1951)
“DR” Requires pharmacists to have either a prescription for certain meds
Kufauver-Harris amendment (1962)
amendment to FDA & C, → mandates pharmaceutical manufacturers to list complications
Drug abuse (1970)
classifies the drugs used in medicine into 5 different schedules
Schedule 1 med:
Schedule 2 med:
Schedule 3 med:
Schedule 4 med:
Schedule 5 med:
=never give, highest abuse potential
=high abuse may have dependence w/ med ind/s (codeine, morphine)
=less abuse potential low dependence (acetaminophen)
=low abuse potential = benzos (diazepam, lorazepam
=lowest abuse potential w/ lil bits of opioids often for cough/ diarrhea
Phase 1 med study
Phase 2 med study
Phase 3 med study
Phase 4 med study
=meds/ pharmacokinetics, toxicity, safe dose (therapeutic dose)
=tested on limited population
=refined therapeutic dose; collects data on side effects
= post-marketing analysis during conditional approval
FDA pregnancy category A:
FDA pregnancy category B:
FDA pregnancy category C:
FDA pregnancy category D:
FDA pregnancy category X:
= studied a lot and had not showed harmful effects to fetus/mom
=animals studies not showed harmful effects but not humans
=animals studies maybe problem w/ no studies on preg/ mother or no good studies on animals/pregnant
= fetal risks have been demonstrated benefits could outweigh risks
=fetal risk demonstrated risk outweighs possible benefits to mother
Pharmacokinetics:
Pharmacodynamics:
=how body works to med
=how med works to med
bioavailability:
Distribution:
= how much the body breaks down the dose
= once med enters bloodstream it muse be moved throughout your body
Biotransformation
METABOLISM→ liver #1 ⅔ filter → means of body filtering medication
Prodrug
body has to break drug down for med to work as intended EX aspirin
Opiate receptors
stops chemoreceptors causing respiratory depressed
Idiosyncrasy
individual reaction is unusually different from what is commonly seen
Tachyphylaxis
rapid occurring tolerance to a medication
Cumulative effect
when med admin/ in several doses causing in increased effect, this is due to a quantitative buildup of the drug in the blood
Competitive antagonist
EX narcan→ finds, and fights for the receptor spot
Non-competitive antagonist
won’t fight for receptor spot
Irreversible antagonist
misshapes cell to where receptor can’t bind from damage/misshaping
Medication antagonism
effects of one med blocks the response to another drug
Summation
2 meds that enhance eachother
Synergism
2 meds are admin/ together that produces a greater response (“1+1=5”)
Potentiation
occurs when med enhances effects of another (promethazine + morphine)
Interference
med directly effects the pharmacology of another “football” EX: non-selective beta blocker w/ albuterol so asthma worsts
Common neurotransmitters:
norepinephrine: Fight or flight & sympathetic response
Epinephrine: fight or flight
acetylcholine= rest digest → parasympathetic response
GABA= main inhibitory neurotransmitter
Glutamate= main excitatory neurotransmitter
Dopamine= pleasure & reward neurotransmitter
Serotonin= mood and helps w/ sleep & digestive regulation
Sympathetic L
Thoratic & Lumbar
Parasympathetic L
Cranial & Sacral
