Define pharmacodynamics.
|
The study of drug interactions including the drug receptors and the series of events that culminates the pharmacologic response.
|
|
Define receptors.
|
The sites on the cells where chemical bonding of drugs occurs.
|
|
Define agonists.
|
Drugs that STIMULATE a response at a receptor site.
|
|
Define antagonists.
|
Drugs that attach to receptor sites but do NOT stimulate a response.
|
|
Define partial agonists.
|
Drugs that interact with a receptor to stimulate a response and concurrently inhibit other responses are partial agonists.
|
|
Define ADME.
|
The four stages of drug processing: absorption, distribution, metabolism, and exretion.
|
|
Define pharmacokinetics.
|
The study of the mathematical relationship among the ADME of medicines.
|
|
Define absorption.
|
The process by which the drug is made available to the body fluids for distribution.
|
|
Define enteral.
|
The enteral route of drug administration is placing the drug directly into the gastrointestinal tract by ORAL, RECTAL, or NASOGASTRIC routes.
|
|
Define parenteral.

|
Define percutaneous.
|
Routes of administration are done via INHALATION, SUBLINGUAL, or TOPICAL.
|
|
Define distribution.
|
The ways in which the drug is transported via the body fluids to the sites of action for metabolism and excretion.
|
|
Drug blood level.
|
Measures the amount of drug present in the blood to determine if it is within, below (subtherapeutic), or above (toxic) the therapeutic range.
