the body, metabolized, and excreted.
Pharmacodynamics - correct answer The study of what the drug does to the body
Factors Affecting Drug Absorption - correct answer Rate of dissolution
Surface area
Blood flow
Lipid solubility
pH partitioning
Factors Affecting Drug Distribution - correct answer Blood flow to tissues
Ability to exit the vascular system
Blood-brain barrier
Protein-binding capacity
Xenobiotics - correct answer substances that are foreign to the body, usually synthetic chemical
compounds; medications are a common example
Cytochrome P450 (CYP450) - correct answer xenobiotic-metabolizing enzymes necessary for
the production of cholesterol and steroids and the detoxification of chemicals and drug

which drugs are oxidized, reduced, or hydrolyzed
Phase 1 Metabolism of Drugs via P450 - correct answer Oxidation; Reduction; Hydrolysis
Three possible outcomes of phase 1 drug metabolism. - correct answer -Drug becomes
completely inactive


-Drug becomes partially inactive but one or more metabolites remain active


-Original drug is not pharmacologically active but one metabolite remains active
CYP450 Inducers - correct answer Medications that can increase the rate of another drug's
metabolism by elevating CYP450 enzyme activity via increasing enzyme synthesis. decreasing
the concentration of the "parent drug"
CYP450 Inducer Medications - correct answer CRAPGPS

,NR565 Advanced Pharmacology Fundamentals
Carbamazepine

Alcohol
Phenytoin
Griseofulvin

another medication's route of entry into the body.
Distribution Interaction - correct answer caused by the amount of unbound/free medications
available at the various target sites.
Metabolism Interaction - correct answer concentration of the medication after
biotransformation into active and inactive metabolites in higher or lower than expected.
Elimination Interaction - correct answer the body's ability to eliminate medications in pure
form or by altering a metabolite from the body.
Pharmacodynamic Interactions - correct answer does not alter or impact absorption,
distribution, metabolism, or elimination because of the one medication's ability to manipulate
the effect of another medication at its site of action
