the study of the history sources & chemical properties of drugs

the study of biochemical and physiological effects of drugs on the body mechanism of action

the study of what the body does to a drug

absorption, distribution, metabolism and excretion

the study of drugs derived from herbal and other natural sources

the study of how drugs can best be used to treat diseases

for chronic illness- prevents progression of disease

Replaces a substance in the body such as insulin and vitamins

Pain relief- to make the patient comfortable

maintains integrity of the body's functions while recovering

PROPHYLACTIC THERAPY

Prevents disease

ex: vaccines

Suspensions

solid particles suspended in a liquid

dispersion of fine droplets of oil in water

drugs that interact with a receptor to produce a response

drugs that interact with cell receptor to block action of an agonist, produces no pharmacological response

STEPS IN PHARMACOKINETICS

1. Liberation: how well the drug is released- bioavailability
2. Absorption:from admin site into body fluids to site of action
3. Distribution:how well drug is distributed
4. Metabolism: biotransformation- first pass effect
5. Excretion: eliminated usually thru kidneys

ONSET

Starts giving therapeutic responses

PEAK

More going in than out

DURATION OF ACTION

from onset to finish

SYNERGISM

2 or more drugs that produce a greater response than would be expected given alone

IDIOSYNCRATIC DRUG REACTIONS

unpredictable and abnormal response to a drug maybe due to genetic difference
