2. Safety
3. Selective
Generic name
Only ONE generic name

*lower case
Trade name

*Upper case
Dose response relationship
Relationship between the size of an administered dose and the intensity of the response produced

Determines;
-minimum amount of drug we can use
-maximum response a drug can elicit
-how much we need to increase the dosage to produce the desired increase in response
First pass (effect) metabolism
rapid inactivation of certain oral drugs

if inactivation is complete (100%) then need to give the drug via ANOTHER ROUTE

if inactivation is incomplete, then give a higher dose
Bioavailability
the percentage of an administered drug that is available in the bloodstream to act at the target tissue
Factors that alter drug metabolism
-age of pt
-route of drug administration/first pass metabolism
-dosage of medication
-generic disposition of the pt
-diet or starvation
-preexisting disease

-levels of intestinal flora
-body surface area
-presence of other drugs
-smoking (induces p450; decreases blood flow)

small molecular weight is greater then excretion
drugs bound to cannot normally pass
GFR is affected by bp
Factors that alter drug administration

IM
SubQ
Oral (PO)
tablets, enteric-coated preparations, sustained-released preparations
*sublingual, topical (gels), inhaled, rectal, vaginal, gas

Receptor Binding
-usually reversible
-activity regulated with by endogenous compounds
-receptor binding will either mimic or block the actions of endogenous regulatory molecules and increase/decrease the rate of physiologic activity controlled by that receptor
Properties of receptors
-normal points of control of physiologic processes
-receptor function is regulated by molecules supplied by the body
-Drugs can only mimic or block the body's own regulatory molecules
-Drugs cannot give cells new function
-Drugs help the body use its preexisting capabilities
-it should be possible to make drugs that can alter the rate of any biologic process for which receptors exist
Agonist
Activates receptors (weak, strong, partial)
Antagonist
prevents receptor activation; do not have efficacy since they do not produce a response
Non-competitive
-binds IRREVERSIBLY to the receptors
-reduce the maximal response
Competitive
-binds reversibly to receptors
-competes with agonist for receptors types
-if agonist and antagonist are both present then the receptor will be occupied by whatever is in the higher concentration
Drug interactions Terms

Addition

1+1=2
Synergism
the combined drugs is GREATER THAN the combined responses of the individual drugs
1+1=3
