Pharmacotherapeutics
● The desired therapeutic outcome should be:
● Individualized
● Collaborative
- specific to patient's problem
- discussing to get maxi um effect
for patient's problem /all healthcare team members)
Outcome goals
● Preventing a disease or unwanted condition
● Ex -
● Improving the quality of life
● Ex. -
Vaccines
managing their symptoms
Critical thinking question
● What is the difference between a
contraindication and an adverse effect?
Contradiction
Adverse
rm -
• situation where we did not • Action/response to drug
administer the drug b/c aware after we
gave
the
of drug
something like liver disease
Adverse Effect
● Any undesirable effects that are a direct
response to one or more drugs.
Types of Therapy (Page #27)
● Acute
● Maintenance
● Supplemental
-0A
intense treatment for a short period of time
type of therapy taken on a
daily everyday to take
drug
everyday to maintain condition
replacementofasubstanuneededmm
for maintaining normal function
ex : different types of vitamins
we take to maintain normal
*insulin is functioning
considered a supplement
bk Our bodies produce it but others
not may
Patient Monitoring
● Therapeutic index- ratio of a drug’s toxic level
to the level that provides therapeutic benefit
● Drug concentration – in blood
● Patient condition – concurrent disease or
other medical condition (infection, GI
function, Cardiovascular function etc.)
take blood to
determine cone to see
if they reached therapeutic level
● Tolerance: decreasing response to repeated drug
doses
● Dependence: physiologic or psychological need
for a drug
● Physical dependence: physiologic need for a drug
to avoid physical withdrawal symptoms
● Psychological dependence: also known as
addiction and is the obsessive desire for the
euphoric effects of a drug

ex : 1mg of morphine for patient for 6 mnths ; may have to up dose to get same affect
ex : 1mg of morphine 1 year; body gets used to- it /patient will have withdraw 1 symptoms
Interactions
● Alteration of the action of one drug by
another drug or food.
● Antagonistic – combination of 2 drugs results
in drug effects that are less than the sum of the
effects for each drug given separately ( 1+ 1=
???)
● Incompatibilities – for parenteral drugs.
1+1 = 12
2 drugs
1+1=7 2 will be reacting if
we administer @ same
time.
if can't mix
drug : 1st and thenmed then flush
administer
next drug
● Other drug effects
● Teratogenic – causes structural defect in fetus
● Mutagenic- causes permanent change in genetic
composition
● Carcinogenic effects- cancer causing effect
