Adv. Pharm NURS 8024 Week 1 Questions 100%
Solved
Pharmacokinetics - Correct Answer what the body does to the drug

Pharmacodynamics - Correct Answer what the drug does to the body

Toxicology - Correct Answer The undesirable effects of chemicals on living systems

Pharmacotherapeutics - Correct Answer dynamic that achieves the desired therapeutic
effect of the drug without causing other undesirable effects

Legend drugs - Correct Answer another name for prescription drugs

Pharmacogenomics - Correct Answer the study of genetically determined variations in
the response to drugs

Pharmacologic Agonist - Correct Answer agent binds to and activates the
receptor - directly or indirectly causing an effect, full or partial agonists

Pharmacological Antagonist - Correct Answer Agent binds to receptor-completes with
other molecules and prevents binding by other molecules-it inhibits other molecules
from binding

Pro-drug - Correct Answer An inactive percursor chemical-must be abosorbed and
distributed and converted to the active form of the drug by biologic processes.

What is ADME? - Correct Answer Absorption
Distribution
Metabolism
Elimination

Absorption - Correct Answer entry of pharmacologic agent into plasma

Distribution - Correct Answer agent leaves the bloodstream and distributes to
interstitial and intracellular fluids

Metablosim - Correct Answer chemical processes that occur to make the drug useful in
the bloodstream--done by the liver, kidney, or other tissue

Ellimination - Correct Answer Leaving the body-via urine, bile, feces, lungs, sweat,
breast milk

2 Major Administration Routes - Correct Answer 1. Enteral -most common, easy,
cheap-BUT drug absorption pathways can be complicated
2. Parenteral-IV, fast, more expensive, once in-cannot get back

, Enteral drug administration - Correct Answer oral, sublingual, rectal
drug absorption pathways complicated
**First-pass metabolism can limit the amount of drug that enters systemic circulation
influenced by food and other drugs

What is first pass metabolism? - Correct Answer The concentration of drug is greatly
reduced BEFORE reaching systemic circulation. This mainly involves liver enzymes, but
also includes gastric enzymes, gut wall enzymes, and bacterial enzymes. Bioavaliability
is reduced.

Parenteral drug administration - Correct Answer -IV, IM, SubQ
- More control over actual dose of drug
- Directly into systemic circulation-bypass first pass metabolism
- used for drugs poorly absorbed by GI
-Rapid onset of action
-Disadvantage: cannot take the drug back, infection risk

Inhalation route of administration - Correct Answer Rapid delivery, large surface area,
good for gases, aerolsols, respiratory drugs

Rectal Route of administration - Correct Answer 50% of circulatory drainage
BYPASSES portal circulation
Meaning: Less first pass effect

Drug Transport Methods: - Correct Answer Passive diffusion (no E needed)
Active transport (requires E)
Endocytosis

Passive diffusion (simple diffusion) - Correct Answer no energy needed, related to
concentration gradient across membrane, HIGHER concentration goes to LOWER
concentration

Active Transport - Correct Answer requires energy (ATP), Able to move drug from
LOWER to HIGHER concentration

Endocytosis - Correct Answer Transport large molecules
Engulfment of drug molecule by cell membrane and transport into cell

Exocytosis - Correct Answer Process by which a cell releases large amounts of
material

Drug Absorption - Correct Answer Drugs are typically weak acids or weak bases
Role and size of MOLECULAR WEIGHT in drug absorption
