which can affect living processes
pharmacology Correct Answer-the study of drugs and their interactions
with living systems

physiological effects of the drugs and the mechanism(s) underlying the
drug effects
pharmakinetics Correct Answer-the study of movement of drugs
throughout the boy, including processes of absorption, distribution,
metabolism, and excretion
therapeutics Correct Answer-(pharmacotherapeutics)
-use of drug to diagnose, treat, or prevent disease

- NOT PHARMACOLOGY
,chemical, generic, brand Correct Answer-3 types of drug names
acetaminophen Correct Answer-generic name for Tylenol (brand name)
diazepam Correct Answer-generic name for Valium (brand name)
selectivity, reversibility of action, efficacy, potency, safety, inexpensive,
easily administered Correct Answer-Characteristic or properties of a
drug (7 of them)
selectivity Correct Answer-(Characteristic or properties of a drug) **
most important
- selective drug is selective toward its receptor site and elicits only the
response for which it is given
reversibility of action Correct Answer-(Characteristic or properties of a
drug)
- usually want only temporary action for a drug
- most drug action is terminated by metabolism to an inactive drug
(biotransformation), by excretion (most frequently through the kidney),
or by combination of theses mechanisms
efficacy Correct Answer-(Characteristic or properties of a drug) ** most
important
- effective drug --> response for which it was given
,- inherent ability of a drug to produce a certain degree of biological
activity. A more efficacious drug can attain a greater biological or
therapeutic response than one which is less efficacious
- at the receptor level term "efficacy" is used to describe a drug's ability
to bind with a receptor and elicit a response
potency Correct Answer-(Characteristic or properties of a drug)
- defined as the biological activity per unit weight
- a more potent drug produces a greater response at the some milligram
dosage than a less potent drug of the same type
safety Correct Answer-(Characteristic or properties of a drug) ** most
important
- a safe drug should produce no harmful effects even if given in high
doses for long time
- safety is relative but very important
inexpensive Correct Answer-(Characteristic or properties of a drug)
- cost if especially important with chronic therapy
easily administered Correct Answer-(Characteristic or properties of a
drug)
- given by a convenient route on an infrequent dosage schedule
drug action Correct Answer-sites of _____:
, 1) extracellular
2) cell membrane: regulatory protein receptors where hormones and
neurotransmitters act to provide chemical communication needed to
coordinate activities of cell and organs
3) intracellular enzyme systems
4) protein synthesis
direct Correct Answer-(drug mechanism)
-drug combines with specific receptors in a cell or tissue to produce its
response
reflex Correct Answer-(drug mechanism)
- drug exerts action by either stimulation of depressing a particlar reflex
system
enzyme inhibition Correct Answer-(drug mechanism)
_____ or induction
metabolic processess Correct Answer-(drug mechanism)
- control of _____
antimetabolite Correct Answer-(drug mechanism)
- drug which is chemically similar to a naturally occurring metabolite
and which competes and produces a deficiency of that metabolite in an
essential biological system
