What are the 2 main action of Tylenol??
What is a problem associated with Tylenol??
Weak ant inflammatory effects
- analgesic= acute mild to mod pain and chronic pain in osteoarthritis and RA
Unlabeled use of Tylenol (3)
decrease fever and pain in children receiving DPT vaccination
Used in patients with gastric irritation from ASA and NSAIDS
DOC for minor pain in children and elderly and adults
How is APAP different from Aspirin?? (3)
- weak antinflammatory effect
- little GI effects
- no impact on platelet aggregation
Maximum daily dose of tylenol
3000 mg per day
4 GM/day if under care of provider
High doses of Tylenol cause??
Tylenol is a metabolite of
avoid tylenol in children younger than ____?
Due to __?
2 years old
MOA of Tylenol as antipyretic
reduces fever by direct action on hypothalamic heat-regulating centers. Inhibits pyrogenic cytokines from acting on heat regulating centers.
Dissipates body heat by vasodilation and sweating.
MOA of Tylenol as analgesic
- centrally acting analgesic.
- works by inhibiting prostaglandin synthetase in CNS.
APAP does not inhibit peripheral prostaglandin synthesis. This is reason is weak anti-inflammatory and does not inhibit platelet aggregations
How often is Tylenol dosed?
every 4-6 hours depending on strength.
Do not exceed maximum daily dose
When used in combo important for provider to monitor daily intake of APAP to avoid overdosage, must warn parents that many OTC preparations have APAP in them
Considerations for elderly and APAP
hepatic insufficiency and at risk for toxicity
use lower doses and increased dosing intervals
watch with care with those taking hepatic toxic drugs, ETOH consumption, and cirrhosis.
pregnancy category APAP
- is excreted in breast milk
Infant drops are ____ times more concentrated than the elixir/solution
APAP may increase _____ prevalence in children
Do not use tylenol in children for more than 5 consecutive days.
Indications of ASA
short or long term symptomatic tx mild to mod pain, inflammation, fever, RA, OA, gout
Reduces risk of TIAs or stroke in pts with TIAs caused by fibrin platelet emboli
Reduces risk of MI, acute ischemic strokes and TIAs
Reduces risk of death or nonfatal MI with previous infarction or unstable angina
May reduce risk of barretts disease
unlabeled use of ASA
toxemia in pregnancy
decreases risk of colorectal cancer
- Mild to moderate pain; dental extractions, minor surgery, soft tissue injury
- primary dysmenorrhea
Unlabeled use of NSAIDS
tendinitis, bursitis, and migraine
GI bleed may occur with ASA and NSAID without ______?
Long term use of NSAIDs (and salicylates) may decrease what disease?
but not if taking for cardioprotective effects
NSAIDS may be associated with increased risk of?
- adverse cardiovascular events
salicylates and NSAIDs reduce inflammation by
inhibiting the production of prostaglandins, prostacyclin, and thromboxane in both CNS and peripheral tissue
Salicylates and NSAIDS reduce pain by
- anti-inflammatory process
- due to decrease in prostaglandin levels= reduction of inflammation
ASA and antipyretic effects
blocks interleukin-1 on the hypothalamus which is responsible for temp control.
causes vasodilation of superficial blood vessel, which dissipates heat
NSAIDs antiplatelet MOA
block COX-1 and the production of thromboxane
have reversible inactivation of COX, only good for duration of drug activity. - this is why ASA is used for prevention of MI and stroke
Platelet activation is stimulated by thromboxane which causes _____ and ______?
aggregation and the clotting cascade
ASA and antiplatelet MOA
- causes irreversible inactivation of COX
- decreasing thromboxane for the 8-10 days life of platelet
NSAIDS are under study for decreasing risk of what diseases
- may decrease parkinsons disease
- reduces risk of colon cancer
inverse link between NSAIDS and breast cancer
ADRS of ASA and NSAIDS (2)
Inhibition of prostaglandins causes more gastric acid production and increased risk of gastric mucosal damage
damaged kidneys rely on prostaglandins for vasodilation, inhibition decreases blood flow to kidneys
Long term use of NSAIDs and Celecoxib (COX-2 inhibitor) can cause
renal papillary necrosis, renal insufficiency, acute renal failure, and other renal injuires.
Pts with impaired renal fx, HF, liver dysfunction; elderly, taking diuretics, ACEIs, and ARBs are at greater risk for this reaction, D/C med and function usually returns to normal.
Patient moderate to severe pain and/or inflammation what is DOC?
COX-2 selective NSAID
unless patient is at risk for HTN and renal disorder.
High doses of NSAIDs may want to consider adding ____ or _____?
PPI or misoprostol
Cardinal points of tx
first line tx
second line tx
Goal of tx are to ____, _____, and _____.
limit inflammatory disease process, protect the joint, and relieve pain
First line for moderate pain
Women of child bearing age should not be given _______?
misoprostol unless appropriate contraception is used. It can cause baby to be aborted.
Get a beta HCG before using
All drugs have generic except _____?
this drug also has _______ properties?
sulfonamide properties- do not use in patients with sulfa allergy
This drug has low Gi adverse effects
This drug should be used cautiously in patients with heart disease
mild OA- tylenol
- If tylenol not effective start on NSAID
- NSAIDs are more effective for OA of knee or hip
COXZ -2 in elderly for long term tx because of decreased GI effects.
Indomethacin has high risk for adverse reactions such as
- aggravates epilepsy and parkinsonism
*short term use only
Patient variables with NSAIDS and ASA use
medical conditions- renal, hepatic, and cardiovascular diseases- many adverse effects related to NSAID use and these conditions!!!
non pharmalogic treatment of OA
walking can improve status
weight loss can reduce strain on joints
cornerstone of non-pharmolgical tx of mild to moderate pain
RICE for 24-48 hours
Muscle injuries, do not use NSAIDS for how long?
24 hours due to effect on platelets
Ibuprofen then usually given for 1-2 weeks
