What does MIC stand for?
Minimum Inhibitory Concentration
What is the Minimum Inhibitory Concentration (MIC)?
The lowest concentration of an antibiotic necessary to inhibit visible bacterial
growth after incubation.
What does MIC stand for in microbiology?
Minimum Inhibitory Concentration
What does the Minimum Inhibitory Concentration (MIC) do?
It is the lowest concentration of an antimicrobial that prevents visible growth
of a bacterium.
What is the significance of MIC in treating bacterial infections?
MIC indicates the amount of antibiotic needed to inhibit bacterial growth
without overkill.
Term: Bioavailability
Definition: The proportion of a drug that reaches systemic circulation and is
available to have an effect after administration.

What is the main organ of biotransformation?
The liver
What is the primary site of drug biotransformation?
The liver
Which enzyme system is mainly involved in drug biotransformation in the liver?
CYP450 enzyme system
Think: “Live(r) to transform
”The liver “lives” to transform drugs into a form the body can eliminate.
Term: CYP450 Inducer
Definition: A medication that increases the clearance of other drugs by
accelerating their metabolism through the CYP450 enzyme system.
What is the effect of an inducer on drug metabolism?
Increases metabolism
What is the result of increased metabolism on drug clearance?
Drugs leave the body faster
What is the effect of an inhibitor on drug metabolism?
Inhibits metabolism
What is the result of inhibited metabolism on drug levels in the body?
Keeps drugs around longer
Term: CYP450 Inhibitor
Definition: A drug that decreases the clearance of other medications by
slowing down their metabolism via the CYP450 enzyme system.
What does a CYP450 inhibitor do to drug clearance?
3/119

AM
It slows clearance.
What is the effect of a CYP450 inhibitor on drug levels in the system?
It keeps drugs in the system longer.
What is a potential risk associated with CYP450 inhibitors?
Higher risk of toxicity.
What is First-Pass Metabolism?
The process where an oral drug is metabolized in the liver after absorption
from the small intestine.
What effect does First-Pass Metabolism have on drugs?
It reduces the amount of active drug entering systemic circulation.
What is the first stop for drugs in the body?
The liver
What does 'first-pass' refer to in pharmacology?
The process where a drug is processed by the liver before it enters the
bloodstream.
What is the therapeutic INR range for stroke prevention with Warfarin?
2.0 to 3.0
What conditions are treated with Warfarin to achieve a therapeutic INR range?
Stroke, DVT, or atrial fibrillation
What does the phrase '2 to 3 keeps the clot from me' refer to?
It refers to the target INR range for warfarin patients.
What is the gold standard INR range for most warfarin patients?
2.0-3.0
