absorption
Definition
First step in how a body handles drugs
Term
absorption
Definition
Movement of drug from site across a body membrane to a target cell
Term
target cell
Definition
where the drug “goes to work” or effects a change/action in the body
Term
drug distribution

Solubility (lipid-soluble drugs)
Definition
three factors effecting distribution
Term
heart, liver, kidneys
Definition
Quick distribution tissues
Term
skin, muscle and other internal organs
Definition
Slow distribution tissues
Term
metablism
Definition
Chemical reactions of drugs in the body
Term
biotransformation
Definition
Chemical conversion of drugs from one form to another, that results in a change in cellular activity in the body (increase or decreased activity)
Term
distribution
Definition
Oral drugs will be metabolized in liver immediately after
Term
first pass effect
Definition
drugs are absorbed in the stomach or across the intestinal wall and directly into the hepatic portal circulation which carries blood directly to the liver
Term
90%
Definition
Liver can actually inactivate __ of the oral drug before it ever reaches the vascular system (first pass effect)
Term
prodrug
Definition
A biologically inactive compound that can be metabolized in the body to produce a drug
Term
prodrugs
Definition
Require metabolism to make them become activated in the body
Term
excretion
Definition
elimination of the drug from the body
Term
half life
Definition
. Length of time required for drug concentration in blood to be reduced by 50% see graph. The time it takes for half of the original amount of a drug to be removed from the body.

Penicillin V” acts on the specific stretococcus bacteria for
Term
receptor
Definition

Term
Idiosyncrasy
Definition
Abnormal, unusual response to a medication, different than expected reaction
Term
tolerance
Definition
Decreased response to a drug that requires increased dosing to obtain desired effects (e.g. narcotics, tranquilizers taken over a long time)
Term
cumulative effects
Definition
Seen in liver and kidney disease, the body is not able to metabolize/excrete a drug dose before another one is given. May lead to drug toxicity
Term
toxic reaction
Definition
Blood levels of a drug are > than therapeutic levels (e.g. Digoxin toxicity)
Term
additive effect
Definition
When two or more drugs with similar pharmacodynamic effects are given, may result in excessive response and toxicity.
Term
Synergistic drugs
Definition
An interaction between two or more individual compounds that produces an effect upon the body GREATER than either of the substances alone would have produced.
Term
