Week 1 Quiz Flashcards
Minimum Effective Concentration [MEC]
the minimum plasma concentration of a drug needed to produce the desired pharmacologic response
Bioavailability
-percent of administered drug that actually makes it to the systemic circulation
First-Pass Effect
- liver metabolizes PO drug
- results in a reduced concentration of the active drug once it reaches the systemic circulation
Blood Brain Barrier [BBB]
highly selective w distribution
-screens out a lot of chemicals
Therapeutic Action
intended effects of the drug
Adverse Reaction
nontherapeutic + unintended effects of the drug that occur at a therapeutic dose
- may be predictable, well known, or unpredictable
- range fr annoying, tolerable to life threatening
Allergic Reaction
most severe type of adverse rxn
-range fr itching + rash to anaphylactic shock
Anaphylaxis
exaggerated response of body’s immune system to a drug
- massive release of histamine+ other chem mediators into into body
- swelling of eyes, face, mouth, throat, difficulty breathing wheezing, rapid HR, low BP, cardiac arrest
Contraindication
- reasons why you should HOLD the drug
- potential to cause serious life-threatening ADR
- ALL DRUGS ARE CONTRAINDICATED IF PATIENT IS ALLERGIC
Therapeutic Classification
“WHY”
ex) analgesic to relieve pain, antihypertensive to lower BP
Pharmacologic Classification
“HOW”
ex) opioids, cholinergic, anticholinergic, benzodiazepine
Chemical Name
scientific name based on the compound’s chemical structure
Generic Name
the official name a company gives a drug they developed
- not capitalized
ex) Tylenol is the brand name, acetaminophen is the generic
Trade [Brand] Name
the drug’s commercial or proprietary name
- capitalized + in parenthesis
- may vary depending on the company producing it
ex) Tylenol is the brand name, acetaminophen is the generic
Addiction
harmful behavior associated with substance abuse
-craving
Dependence
the body requires a specific dose of a particular drug, such as a prescription opioid, in order to prevent withdrawal symptoms
7 Methods of Action of Drugs
1 stimulation 2 depression 3 irritation 4 replacement 5 cytotoxic 6 antimicrobial 7 mod of immune status
Tachyphylaxis
an acute, sudden drop in response to a drug after its administration
i.e. a rapid and short-term onset of drug tolerance
Additive Effect
when the combined effect of 2 drugs you give together is THE SAME as each drug you give alone in same doses
- 1+1=2
Synergistic Effect
when the effect of 1 drug is GREATER if you give it w another drug
- 1+1=3
Controlled Substance
medications that can cause physical and mental dependence, and have restrictions on how they can be filled and refilled
-regulated + classified by the DEA (Drug Enforcement Admin
Teratogenic drug classification
drugs/foods that a pregnant woman can ingest + can cross placenta into fetus
- can cause malformation of developing fetus
- CATEGORY D = possible risk
- CATEGORY X = relationship w fetal malformation
Therapeutic Range / Index
concentration of drug in the blood serum that produces the desired effect wo toxicity
Plasma HALF-LIFE of drug
amount of time it takes for 50% of blood concentration of drug to be eliminated fr body
