LESSON 11: Antipyretics Flashcards
Body temperature is controlled by the _________
hypothalamus
This is where (1) warmth/cold receptors in the skin and the (2) from the temperature of the blood bathing the regio
Range of 36.5 - 37.5oC (97.7 - 99.5oF)
Rectal temperatures are
generally
0.4oC (0.7oF) higher than oral readings
A fever of >41.5oC (>106.7oF) is called
hyperpyrexia
is characterized by an uncontrolled increase in body temperature that exceeds the body’s ability to lose heat.
Hyperthermia (heat stroke)
T/F: Hypothermia Do not respond to antipyretics
True
a substance causing induction of a febrile response which can be fatal in humans and animals
Pyrogen
are
derived from outside the patient; most are microbial products, microbial toxins, or whole microorganisms (including viruses).
Exogenous pyrogens
the lipopolysaccharide complex associated with the outer membrane of ALL gram-negative bacteria.
bacterial endotoxin
highly biologic or biogenic molecules in humans, produces fever or leukocytosis or even generalized symptoms of varied malaise or weakness
Endotoxins
Reactions to endotoxins lead to
anaphylactic shock and death of patient
Pyrogenic products of gram-positive organisms include the enterotoxins of _______________ and the A and B streptococcal toxins, also called
Staphylococcus aureu; superantigens
is associated with microbiological contamination of parenteral products
Pyrogenicity
Common MOA of NSAIDs
Inhibits cyclooxygenase → inhibits prostaglandin
Examples of NSAIDs
Diclofenac

Ketorolac
Piroxicam
Ketoprofen
Nabumetone
Ibuprofen
Indomethacin
Mefenamic acid
Tenoxicam
Phenylbutazone
