definition of pharmacology
the study of drugs and their interactions with living systems
what is a drug? (2-part)
- any chemical that can influence living process
- a substance that is capable of interacting with living organisms to produce biological effects
three categories of drug use:
1) prescription drug
2) nonprescription drug
3) controlled drug
prescription drug
provided by a licensed healthcare professional
nonprescription drug
a.k.a. over-the-counter (OTC)
used safely without the supervision of a licensed healthcare professional
controlled drug
may lead to drug abuse or dependence; use controlled by federal, state, and local laws
definition of pharmacotherapeutics
the use of drugs to diagnose, prevent, treat disease, or prevent pregnancy; the medical use of drugs
definition of pharmacokinetics
what the body does to the drug
the four processes of pharmacokinetics
- absorption
- distribution
- metabolism
- excretion
definition of pharmacodynamics
- what the drug does to the body
- mechanism by which drugs produce biochemical or physiological changes in the body
- outcomes of the drug response
the three properties of an ideal drug
1) effectiveness
2) safety
3) selectivity
which of these ideal properties is the most important?
effectiveness! if it doesn't work, then what's the point?
is there such a thing as a safe drug?
nope.
other properties of drugs
- reversibility
- predictability
- ease in administration
- decreased drug interactions
- cost
three kinds of factors determining intensity of drug response
1) physiologic
2) drug interactions
3) pathophysiologic
examples of physiologic factors
- age
- weight
- body water content
- fat content
- genetic and ethnic considerations
pathophysiologic factors that influence drug response
- cardiovascular
- GI
- renal
- thyroid
- liver
how does the cardiovascular system affect drug response?
it decreases all pharmacokinetic properties
how does the GI tract affect drug response?
it alters drug absorption
how do renal things affect drug response?
it alters drug excretion
how does the thyroid affect drug response?
it alters drug metabolism
how does the liver affect drug response?
it alters drug metabolism and drug effects
the nursing process in drug therapy
- assessment
- analysis/nursing diagnosis
- planning
- implementation
- evaluation
sources of data for assessment
- patient interview/history
- physical exam
- lab findings
- diagnostic tests
medication history part of which step in the nursing process?
assessment; notes allergies, medical history, dietary habits, personal/lifestyle/beliefs, sensory deficits, other drugs, and capacity for self-care
what happens in the baseline data step of assessment?
the determination of how effective a drug is and determination of the drug's side effects
nursing diagnosis is related to... (2)
- side effects of drugs
- lack of knowledge/inability to adhere to medication regimen
planning involves...
- collaborating between nurse and patient
- involving the family/significant others
- maximizing therapeutic effects
- minimizing adverse effects
8 rights of implementation
- right drug
- right preparation
- right storage
- right dose
- right route
- right time
- right patient
- right documentation
three types of names for drugs
chemical, trade (tylenol), generic (ex. acetominophen)
phase 1 for drugs
normal, healthy volunteers to test metabolism and biological effects
phase II
small group of people with diseases for effectiveness/dosage range
phase III
larger number of volunteers with disease/illness for clinical effectiveness, dosage range, safety
phase IV
continued surveillance
expedited approval
shortens the drug approval process, and is typically for drugs of serious/life-threatening health problems
