answers
Define: Drug Correct Answer-*A chemical substance used to treat or
prevent a disease or condition.*
Almost all chemicals can be considered drugs, because, when we get
enough exposure, all chemicals can affect life.
Used for diagnosis of disease conditions, treatment of disease, and for
prevention of illness or pathologic states

The unique combination of several biomedical sciences
The study of drugs and the origin, nature, properties and effects upon
living organisms.
Define: Clinical Pharmacology Correct Answer-*The study of the
effects and movements of drugs in the human body.*
,All aspects of the interaction between drugs and people
Deine: Therapeutics (Pharmacotherapeutics) Correct Answer-*The study
of the therapeutic uses and effects of drugs.*

produce harmful effects—even if administered in very high doses and
for a very long time.

What is the "therapeutic objective" of drug therapy? Correct Answer-
*Drug therapy should provide maximal benefit with minimal harm.*
What affects the intensity of a drug response? Correct Answer-*For each
drug and individual person, the concentration of the drug at its sites of

Answer-Administration
Pharmacokinetics
Pharmacodynamics
, Individual characteristics of the patient

Processes (ADME):
Absorption
Distribution
Metabolism
Excretion
How does pharmacodynamics affect the intensity of a drug response?
Correct Answer-*What the drug does to the body.*
Drug-receptor interaction
- Binding of the drug to its receptor
