NSAIDS & Tylenol Jane E. Smith, MHSA, RN, C, ONC

Objectives  Review the pathophysiology of the inflammatory response  Discuss the mechanism of action for non-steroidal anti-inflammatory drugs and Tylenol  Discuss the indications, side effects, and nursing implications related to NSAIDS and Tylenol  Identify key information to include in patient/family education

NSAIDS and Tylenol

Pain Management  Causes Primary Infection Pathogenesis  The ABC’s Ask Believe Choose Deliver Empower Follow-up Wayne Heim/arthrw.jpg

Inflammatory Response  Triggers  Provoking Factors Physical & Chemical Infectious Agents Art from: MayoClinic.com

Evolution of Inflammation Injury  Release of Kinins & Histamines  Vasoconstriction  Vasodilatation   Capillary Permeability  Swelling  Pain and Impaired Function

Tylenol  Properties  Indications  Dosage  Hepatotoxicity

NSAIDs – How do they work?

NSAIDs – Many Categories (COX-1)  Carboxylic acids Acetylated salicylates Nonacetylated salicylates Acetic acids  Propionic acids Ibuprofen Naproxen  Fenamates Meclomen  Pyrazoles  Oxicams Piroxicam (Feldene)

Cyclooxygenase (COX – 2) Inhibitors

Cox–1 and Cox–2 Drugs Indications  Rheumatoid Arthritis  Osteoarthritis  Juvenile Arthritis  Dysmenorrhea  Fever

Cox–1 and Cox–2 Drugs Contraindications  Angioedema  Syndrome of nasal polyps  Bronchospasm reaction to ASA or other NSAIDs  Hypersensitivity

Cox–1 and Cox–2 Drugs Drug to Drug Interactions  Antihypertensives, thiazide diuretics, lasix - NSAIDs  effectiveness of these meds  NSAIDs  digoxin and lithium levels  Sun exposure – photosensitivity

Cox–1 and Cox–2 Drugs Side Effects  Gastrointestinal bleeds  Hematologic changes-  bleeding time, various anemias (prolongs INR,  BUN & K+,  blood glucose levels)  Renal – acute renal failure

Cox–1 and Cox–2 Drugs Patient/Family Education  Take medication with food  No ASA  No ETOH  Use sunscreen

Efficacy of Cyclooxygenase-2-Specific Inhibitors  COX-2 specific agents superior to placebo and equivalent to conventional NSAIDs  COX-2 specific inhibitors offer advantages over conventional NSAIDs on the basis of decreased toxicity but not in terms of efficacy.  The role and guidelines for the use of COX-2 inhibitors should be based on toxicity and other issues.

Costs of NSAIDS vs. Tylenol McPhee, S. J., Pignone, M., & Schroeder, S.A. (2002) DrugCost Per UnitCost Per 30 Days ASA$0.01/325 mg$3.60 Tylenol$0.01/325 mg$3.60 Toradol$0.93/10 mgNot recommended for > 5 days Motrin$0.28/600 mg$33.60 Naproxen$1.16/500 mg$ Celebrex$2.52/200 mg$75.60 – OA $ RA Vioxx$2.52/12.5 mg$ OA

Key Points  NSAIDs are effective in the management of pain by interrupting prostaglandin synthesis.  Tylenol is an effective medication in the management of pain but it has no anti-inflammatory action.  COX-1 and COX-2 Inhibitors have similar efficacy in the management of pain.  NSAIDs have significant side effects and patient/family teaching is an integral component of the treatment plan.
