What the BODY does to the DRUGS
|
PHARMACO- KINETICS
|
|
What are the combined focus of pharmacokinetics?
|
ABSORPTION into
DISTRIBUTION within METABOLISM within EXCRETION from |
|
The movement of a drug from its site of administration into the bloodstream for distribution to the tissues
|
ABSORPTION
|
|
The chemical form of a drug that is administered before it is metabolized by the body's biochemical reactions into its ACTIVE or INACTIVE metabolites
|
PARENT DRUG
|
|
An inactive drug dosage form that is converted to an active metabolite by various biochemical chemical reactions once it is inside the body
|
PRODRUG
|
|
The extent of drug absorption for a given drug and route (from 0% - 100%)
|
BIOAVAILABILITY
|
|
The initial metabolism in the LIVER of a drug absorbed from the GI tract before the drug reaches systemic circulation through the bloodstream
|
FIRST-PASS EFFECT
|
|
The drug is absorbed into the systemic circulation through the mucosa of the stomach or small intestines
|
ENTERAL
|
|
The fastest route by which a drug can be absorbed. Most commonly refers to injection by any method. IV injections delivers the drug directly into the circulation.
|
PARENTERAL
|
|
Drugs are absorbed into the highly vascularized tissue under the tongue or the oral mucosa between the cheek and gum
|
SUBLINGUAL and BUCCAL
|
|
Involve the application of medications to various body surfaces - skin, eyes, ears, nose lungs, rectum or vagina
|
TOPICAL
|
|
Refers to the transport of a drug in the body by the bloodstream to its site of action. Drugs are distributed first to those that are most extensively supplied with blood- heart, liver, kidneys, and brain
|
DISTRIBUTION
|
|
What organ is responsible for the metabolism of drugs
|
LIVER
|
|
It involves the biochemical alteration of a drug into an inactive metabolite, a more soluble compound, or a more potent active metabolite
|
METABOLISM / BIOTRANSFORMATION
|
|
The elimination of drugs from the body
|
EXCRETION
|
|
The most common blood protein carries that majority of protein-bound drug molecules
|
ALBUMIN
|
|
TRUE or FALSE
Certain conditions that can cause low albumin levels ( extensive burn or malnourished) result in the presence of a larger fraction of free (unbound or active) drug risk of drug toxicity |
TRUE
|
|
Occurs when the presence of one drug decreases or increases that actions of another drug administered concurrently.
|
DRUG-DRUG INTERACTION
|
|
Various areas in which drugs may be distributed
|
VOLUME OF DISTRIBUTION
|
|
TRUE or FALSE
Drugs that are WATER-SOLUBLE and HIGHLY PROTEIN BOUND are more strongly bound to proteins in the blood and are LESS LIKELY to be absorbed into tissues and because of this, their DISTRIBUTION and onset action can be SLOW |
TRUE
|
|
TRUE or FALSE
Drugs that are HIGHLY LIPID-SOLUBLE and POORLY BOUND to PROTEIN are more EASILY taken up into tissues and distributed into the circulation from tissue |
TRUE
|
|
TRUE or FALSE
Poor blood supply like bone and physiologic barriers like brain or a placenta make it difficult for drugs to pass through |
TRUE
|
|
Enumerate the type of Biotransformation (4)
|
OXIDATION
REDUCTION HYDROLYSIS CONJUGATION |
|
Increase in polarity of chemical, making it more water soluble and more easily excreted, thus often results in a loss of pharmacologic activity
|
OXIDATION
REDUCTION HYDROLYSIS |
|
Combination with another substance
|
CONJUGATION
|
|
Primary organ responsible for elimination of drugs from the body
|
KIDNEY
|
|
Arrange these excretion process in order:
Active Tubular Secretion, Glomerular Filtration, Active Tubular Reabsorption |
1. GLOMERULAR FILTRATION
2. ACTIVE TUBULAR REABSORPTION 3. ACTIVE TUBULAR SECRETION |
|
The time required for one half of a given amount of drug in the body to be removed and is a measure of the rate at which the drug is eliminated from the body
|
HALF-LIFE
|
|
In which the amount of drug removed via elimination is equal to the amount of drug absorbed with each dose
|
STEADY STATE
|
|
The physiologic reactions of the body to the drug
|
DRUG EFFECTS
|
|
The time required for a drug to elicit a therapeutic response after dosing
|
ONSET ACTION
|
|
The time required for a drug to reach its maximum therapeutic response
|
PEAK EFFECT
|
|
The length of time that the drug concentration is sufficient (w/out more doses) to elicit a therapeutic response.
|
DURATION OF ACTION
|
|
lowest blood level of a drug
|
TROUGH LEVEL
|
|
Tablets, capsules, pills, TR capsules/tablets, rectal suppositories are _______dosage forms.
