Cards

Term
Drug Chemical Name
Definition

Gives a precise description of the drug's chemical composition.

 

Not usually used unless it is short and sweet.

 

Example:

the chemical name for tetracycline is:

 

4-dimethylamino-1,4,4a,5,5a,6,11,12a octhydro0-3,6,10,12,12a pentahydroxy-6-methyl-1,11-dioxo-2-napthacenecarboxamide

Term
Generic Drug Name
Definition
The generic drug name is the non-proprietary name, thought up by the manufacturer and it is the original name. Usually derived from the drug's chemical structure. Also the "Official name"
Term
Official Drug Name
Definition
The official drug name is the same as the generic name of the drug.
Official Drug name = Generic drug name
Term
Drug Trade Name
Definition
The Trade name is the Brand name, the name under which a drug is marketed. Copyrighted for 7 years and owned by whoever brought it to market.

A generic drug can have a LOT of trade names.

written as: Panmycin(tetracycline)
Term
Therapeutic Drug Class
Definition
Useful to know in order to describe what the drug effects, but not useful in describing how a drug works.
antitussive
analgesic
anticoagulent
Term
Pharmacologic Drug Class
Definition

Explains how the drug acts. Much more specific than the therapeutic class.

Beta-blockers are all chemically similar.

Sulfa drugs are all chemically similar.

Aceinhibitors very similar.

 

Pharmacologic class is the BEST way to learn drugs

Term
Orphan Drugs
Definition
An orphan drug may treat a very rare disease or have particularly harmful side-effects. Because of it's risk or lack of demand, or cost to produce, they don't get adopted by any particular drug company.
Term
Prototype drug
Definition
All drugs in a class are compared to a Prototype Drug. By learning the prototype drugs in depth, you will have a very good idea of how all the drugs that are compared to it work.
Term
Combination Drug
Definition
Combination drugs contain more than one active ingredient.

example:
Cozaar is a combo of Losartan + HCTZ (reduces BP)
Term
Pharmacodynamics
Definition
Pharmacodynamics describes what a drug does to the body.
Does it promote cell function?
Does a drug alter body fluids?
Does it accelerate or slow cell responses?
Term
Receptor Theory of Drug action
Definition

The Receptor Theory of Drug action is defined as a lock and key mechanism.

 

Receptors can be in a cell membrane, a lipid, a specific organ's cells, blood, tissuses, hormones...

Term
Desentization in the Receptor Theory of Drug Action
Definition
Desensatization is a decrease in response after continued stimulation of the receptor. example: Your three-year-old says "mama, mama, mama, mama..." a billion times a day. You hear it at first, but then become desensatized and do not hear it as much. refractoriness is the extreme of this - the receptors no longer respond to the drug.
Term
Refractoriness in drug desensitization
Definition
refractoriness is an extreme of drug desensitization - the receptors no longer respond to the drug at all.
Term
Hyperreactivity in drug sensitization
Definition
hyperreactivity is an extreme of drug sensitization - instead of being desensatized to a drug, receptors become hypersensative or hyperreactive. Sometimes due to the bodies creation of new receptors. Examples: welbutrin, adavan
Term
Agonist
Definition

An agonist is a drug that turns on receptors.

 

A beta-agonist turns on all beta-receptors.

Term
Antagonist
Definition

An antagonist is a drug or food that turns off receptors.

 

example: Beta-blockers turn of the beta-receptors.

Term
Selective toxicity
Definition
Selective toxicity is a drugs ability to attack ONLY the enzyme systems found in FOREIGN CELLS. Antibiotics target only foreign cells. (If they attacked enzymes in your own cells, you'd be screwed)
Term
Critical Concentration
Definition
Critical concentration is the amount of drug needed to cause a therapeutic effect. Drugs need to reach their site of action in a suitable form to maintain an appropriate concentration.
650mg of aspirin will help a headache
81mg will "make your platelets less "gooey"
critical concentration of a drug depends on what therapeutic effect you are going for.
