Pharmacology
|
The study of drugs in its broadest sense, including interactions between drugs and body constituents at any level of organization.
|
|
Pharmacodynamics
|
What the drug does to the body;includes mechanisms of action of drugs at physiological,biochemical,and molecular levels.
|
|
Pharmacokinetics
|
What the body does to the drug;how drug concentrations in body fluids and tissues vary with time and intensity of response.
|
|
Pharmacogenetics
|
The relationship of genetic factorsto variations in drug responsiveness.
|
|
Receptor
|
Specific macromolecule that is the target for drug binding; initial "site of action" of a drug.
|
|
Therapeutic index aka "margin of safety"
|
Ratio between the dose of drug causing undesirable effects
and the dose causing the desired therapeutic response. |
|
Toxicology
|
Study of poisons, their effects, their antidotes, and drug overdoses.
|
|
Proprietary name
|
Brand or trade name of a drug that is the patented property of the drug manufacturer; drugs of identical composition may have many different proprietary names
|
|
Pharmacologic antagonist
|
A drug that binds to its receptor without activating it
|
|
Physiologic antagonist
|
A drug that binds to a different receptor causing an effect that counteracts the effects of another agonist
|
|
Chemical antagonist
|
A drug that binds another drug and prevents the bound drug’s pharmacologic effect
|
|
Irreversible antagonist
|
A pharmacologic antagonist that cannot be overcome by
increasing the concentration of another agonist |
|
Competitive antagonist
|
A pharmacologic antagonist that can be overcome by increasing the concentration of another agonist
|
|
Agonist
|
a drug that activates its receptor upon binding
|
|
Effector
|
component of the biologic system that accomplishes the biologic effect after being activated by the receptor; often a channel or enzyme.
|
|
Partial agonist
|
a drug that binds to its receptor but produces a smaller effect at full dosage than a full agonist
|
|
Quantal dose response curve
|
a graph of the fraction of its population that shows a specified response to increasing doses of a drug
|
|
Potency
|
the dose or concentration required to bring about 50% of the drug's maximum effect
Spare receptors receptors that do not have to bind drug in order for the maximum effect to be produced |
|
Efficacy
|
maximum effect a drug can bring out regardless of does
|
|
Inert binding site
|
component of the biologic system to which a drug binds without changing any function
|
