Info Flashcards
Generic name
Registered name written in lowercase
Chemical name
Gives chemical structure often long and difficult to remember
Tradename
Also known as brand-name always begins with a capital letter
Pharmocology
Study of biochemical and physiologic Properties medication
Pharmacokinetics
Refers to how the body ask on a medication including how the drug is absorbed into the bloodstream, distributed throughout the body, and how body metabolizes drug along with how the body eliminates the drug
Pharmacodynamics
How are drug works in interacts with various receptors
Dose response relationship
As the dose of medication increases so does the psychological effect until increasing the medication no longer produces an increase in the desired physiological effect
How long does it take for oral medications to take effect
30 minutes to one hour
Enteral administration
Absorbed through the G.I. track
First pass metabolism
When a jug goes through the G.I. track and go through the liver it can be partially metabolized reducing the amount of medication available for distribution in the body
Parenteral
Medication’s that bypass the G.I. track
Non injectable parenteral routes include
Topical, intranasal, inhalational
Injectable medication’s are
Intramuscular, intravenous, introosseous and subcutaneous
Bioavailability
The percentage of an administer drug that is available in the bloodstream to act at the target tissue
Half-life
Time required for the concentration of a medication in the bloodstream to decrease to half of its original level
Duration of action
The amount of time a single dose of medication produces the desired effect
Nebulized
Medication made into smaller particles by a delivery device and then given through inhalation
 First pass metabolism
Medication given orally requires a significantly higher dose than the same medication given by a parenteral route
Drug excretion
Removal of a drug or metabolite from the body.
Kidneys often play a role in removal of drug and drug byproducts
First order kinetics
Aka Exponential kinetics of absorption
Discuss is only a fraction of the medication is absorbed into the bloodstream when given any other route other than through an IV. This is due to absorption in the intestinal track
Zero order kinetics
When a drug is given through IV 100% of the medication is available in the bloodstream
Volume of distribution
The space that the drug would occupy it is expressed as milligrams/liters or such
Passive diffusion
When medication penetrate cells by simply crossing through the cells membrane
Carrier mediated facilitated diffusion
Transportation of a drug into a particular cell depends on a second molecule to carry the drug molecules into the cell
Saturable process
When the concentration of drug outside the cell increases the rate of transporting the drug into the cell increases. This is connected with Carrier meditated facilitated diffusion. However once the drug reaches a certain concentration no more drug can enter the cell without the carrier present
Active transport
Drug requires a macromolecule to assist in transport. The drug is capable of reaching a point of saturation. Requires energy
Passive transport
When a molecule moves down a concentration gradient from an area of high concentration to an area of low concentration
Endocytosis
So essentially forms a sack around the drug molecule with the sales membrane and the cell membrane folds inward bringing the drug into the cell
Onset of action or Latent period
Time interval from administration to desired effect
