Q

What is the difference between PO and parenteral medications?

A

PO: relies on GI system to break down medication to be absorbed prior to distribution

Parenteral: bypasses GI system to distribute throughout body

Q

What the drug does to the body is referred to as?

A

Pharmacodynamics

Relationship between the concentration of a medication and its action

21
Q

In what 3 ways can drugs increase or inhibit a physiological effect?

A
  • receptor interactions
  • enzyme interactions
  • non-selective interactions
22
Receptors are ___________?
interactive sites on the surface of or inside the cell
23
________ is how well the medication binds to a receptor
affinity
24
What happens the more the affinity?
The stronger the response
25
What do agonists do?
Agonists elicit a response
26
What do antagonists do?
Antagonists inhibit a response
27
what are enzyme interactions?
Occur when drug molecule binds to an enzyme. Can increase the action of an enzyme or block it.
28
enzyme interactions are __________ because they target a particular enzyme
selective interactions
29
Medications with _________________________ don’t target enzymes or receptors, they interact with cell membranes/walls or with particular processes
Non-selective interactions
30
Define Toxicology
pertains to the adverse effects of substances on living systems
31
Define Tolerance
decreasing response to drug dose
32
Define Dependence
can by physiological or psychological
33
More complex form of dependence, influenced by many psychosocial factors is ____________
addiction
34
What is pharmacokinetics?
What the body does to a drug.
35
4 types of pharmacokinetics
Absorption, distribution, metabolism, excretion
36
what is Absorption?
how the medication enters the body
37
what is bioavailability?
Extent of absorption
38
What factors will affect bioavailability in PO?
- food in GI tract - other medications - sepsis - exercise - bariatric surgery these will decrease absorption
39
What factor will affect bioavailability in IM/SC?
Heat can increase absorption
40
What medications are 100% bioavailable?
IV fluid
41
What is first-pass effect?
Drugs absorbed via GI tract altered by liver prior to absorption in the intestines
42
How does first-pass effect affect bioavailability?
Reduces bioavailability, sometimes significantly
43
Define distribution
how the drug moves through the body
44
Distribution is fastest at _______ ?
highly vascular areas Binds to plasma proteins such as albumin
45
is bound or unbound are pharmacologically active ?
unbound
46
When two drugs compete for binding sites, its called ________
drug-drug interactions
47
1+1=2 is classified as an _______
additive
48
1+1=3 is classified as ________
synergistic
49
1+1=less than 2 is classified as _________
antagonistic
50
Example of sites that are difficult for medications to reach
blood-brain barrier
51
What is teratogenic?
harmful to fetus
52
What is metabolism?
refers to the chemical reactions which occur in the body
53
______________ is how the chemistry of a medication is altered as it passes through the body
Biotransformation
