Ch 24 Pain Meds Flashcards
(40 cards)
What is fever the result of
It is the result of fever inducing substances called pyrogens
What does fever activate
Fever causes activation of monocytes/ macrophages, which in turn secrete cytokines, which increase the synthesis and secretion of prostaglandin in the hypothalamus, this in turn causes the hypothalamus to reset the body temp
What are the classic signs of inflammation
Swelling, heat, redness, pain, loss of function
What do prostaglandins modulate
They modulate some components of inflammation, body temp, pain transmission, platelet aggregation, and many other body actions.
Cox 1
Synthesizes prostaglandins that are involved in the regulation of. Oral cell activity
Cox 2
Appears to produce prostaglandins mainly at sites of inflammation
Where does the sensation of peripheral pain begin
It begins in averted neurons called nociceptors, these receptors are activated by chemical mediators, such as prostaglandins, histamine,bradykinin, and serotonin.
The risk of platelet aggregation increases in who
Patients who smoke and have hypercholesterolemia
What are the 2 major types of migraine headaches
Migraine with aura
Migraine without aura
How do migraine headaches begin
It is postulated that migraines begin when intracranial blood vessels dilate.
What is the drug treats inflammation and fever

salicylates are used in managing conditions ranging from a simple headache to MI
they are used primarily as anti inflammatory drugs but are also used extensively as analgesics.
What is the Pharmacotherapeutics of aspirin
Treats mild to moderate pain, prevents platelet aggregation
What are contraindications and precautions of aspirin
Hypersensitivity
peptic ulcer disease
Bleeding disorders
Children with illness
What are adverse effects of aspirin
Renal failure Abnormal bleeding GI upset Drowsiness Confusion
During what stage in pregnancy is aspirin contraindicated
In the last trimester

What is aspirin contraindicated in children with illness
It is contraindicated in children with varicella or flu like illness because it is assoc with the occurrence of REYE SYNDROME
What are NSAIDS
They are grouped by chemical class
They all inhibit COX and prostaglandin synthesis
They all carry a black box warning stating that they increase the risk if MI and stroke
What is the prototype NSAID
Ibuprofen
What is ibuprofen used for
Arthritis Mild to moderate pain Primary dysmenorrhea Migraine headaches Fever
When does ibuprofen peak
1-2 hours
What is the paharmacodynamics of ibuprofen
It inhibits synthesis or release Of prostaglandins
Ibuprofen is contraindicated in who
GI DISEASE
What are adverse effects of ibuprofen
GI upset & bleeding
Hepatotoxicity
