85
Harrison-Narcotic act (1914):
aimed a controlling the importation, manufacture, & sale of opium & coca plant & its derivatives
86
FDA & Cosmetic act (1938)
truth-in-labeling cause→ state whether prep has habit-forming drugs and its%
87
Durham-Humphrey amendments (1951)=
requires pharmacists to have either a prescription for certain meds
88
Kufauver-Harris amendment (1962)=
amendment to FDCA, → mandates pharmaceutical manufacturers to list complications

Schedule 1 med: Schedule 2 med: Schedule 3 med: Schedule 4 med: schedule 5 med:
=never give, highest abuse potential =high abuse ~dependence accepted med indi/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

=studied a lot and had not showed harmful effects to fetus/mom =animals studies hadn't showed harm effects to animals but not humans =animals studies pos/ prob/ w/ no studies on pregnant mother no good studies on animals/pregnant = fetal risks have been demonstrated benefits could outweigh risks =fetal risk demonstrated risk outweighs possible benefits to mother
93
Med Bioavailability: Med Biotransformation: Med Prodrug:
=how much the body breaks down the dose =METABOLISM→ liver #1 ⅔ filter → means of body filtering med =body has to break drug down for med to work as intended EX aspirin
94
Idiocrasy effect: Cross tolerance effect: Tachyphylaxis effect: Cumulative effect: Med antagonist effect: Summation effect: Synergism effect: Potentiation effect: Interference effect:
=individual reaction is unusually dif/ from what is commonly seen = body builds up tolerance to 1 med thus, tolerance to another med =rapid occurring tolerance to med = when med admin/ in many doses thus increased effect, due to quantitative buildup of the drug in the blood =effects of one med blocks the response to another drug =2 meds that enhance each other = 2 meds admin/ together that produces a greater response (“1+1=5”) =when med enhances effects of another (promethazine + morphine) =med directly effects the pharm/ of another “football” EX: non-selective beta blocker w/ albuterol so asthma worsts
95
Bioequivalence: Assay: Bioassay: Efficacy: Teratogenic med:
=relative therapeutic effectiveness of chemically equivalent med/s = test done to determine the amount of purity of a given chemical =test to ascertain a med/s in a biological model = ability of med/ to cause a expected response =medication that can kill/deform the fetus in the mother
