    3. COX1 Enzyme
      1. Location
        1. Gastric mucosa and intestinal mucosa
        2. Platelets
        3. Renal
        4. Vascular endothelium
      2. Inhibition Effects
        1. Predisposes to gastric or intestinal ulcers
        2. Predisposes to bleeding (anti-platelet adhesion)
        3. No anti-inflammatory effect
        4. Renal effects
          1. Fluid retention
          2. Decreased Glomerular Filtration Rate (GFR)
    4. COX2 Enzyme

        1. Brain
        2. Renal (ascending tubule, Macula densa)
        3. Adenoma (colon)
        4. Cytokine-induced (inflammation related)
      2. Inhibition Effects
        1. Anti-inflammatory action
        2. Analgesic action
        3. Predisposes to renal injury in hypovolemia
        4. Decreased malignant potential of Colonic Polyps
        5. May have benefit in Alzheimer's Disease
  3. Precautions
    1. Peptic ulcer risk, nephrotoxicity, and cardiovascular risk are FDA black box warnings
  4. Adverse Effects
    1. NSAID Gastrointestinal Adverse Effects
    2. NSAID Renal Adverse Effects
    3. Bleeding risk
      1. Reversible inhibition of platelet aggregation
      2. Associated with standard NSAIDs (esp. Naprosyn)
      3. COX2 Inhibitors have minimal effect on bleeding
      4. Avoid in patients with Thrombocytopenia and other platelet disorders
      5. Stop Aspirin 7-10 days before procedures
      6. Stop NSAIDS five half-lives prior to the procedure
        1. Stop Ibuprofen 2 days before the procedure
        2. Stop Naprosyn 2-3 days before the procedure
        3. Stop piroxicam (Feldene) 10 days before the procedure
    4. Headache
    5. CNS effects (esp. Indomethacin)
    6. Musculoskeletal effects
      1. May delay healing in Tendinopathy
      2. Increased malunion risk in long bone Fractures (Femur Fracture, Tib-Fib Fracture, humerus Fracture), Odds Ratio 2
        1. NSAIDs blunt inflammatory response which is key to laying down new bone
        2. Jeffcoach (2014) J Trauma Acute Care Surg 76(3): 779-83 [PubMed]
      3. However other human trials have not found significant delayed Fracture healing

        3. Dodwell (2010) Calcif Tissue Int 87:193-202. [PubMed]
    7. Cardiovascular/cerebrovascular risk (interferes with Aspirin anti-platelet effects)
      1. Avoid NSAIDs in patients with vascular disease (risk increases within days of use)
      2. Naprosyn (Naproxen) may be associated with less cardiovascular risk than other NSAIDs
      3. Increased risk with Diclofenac and COX-2 Inhibitors, and to a lesser extent Ibuprofen
      4. Take Aspirin 2 hours before or 8 hours post-Ibuprofen
      5. Take Aspirin 36 hours after last Naproxen
      6. Limit NSAID to lowest dose and shortest duration
      7. Steinhubl (2005) Am College Card 45:1302 [PubMed]
      8. (2013) Lancet 382(9894):769-79 +PMID:23726390 [PubMed]
    8. Hypertension
      1. On average NSAIDs increase Blood Pressure 5 mmHg
      2. Blood Pressure increase is more common in Diabetes Mellitus, Congestive Heart Failure, Kidney or liver disease
      3. Associated with daily use (intermittent use is unlikely to have an effect)
      4. Calcium Channel Blockers are less affected by NSAID induced Blood Pressure increases
    9. Allergic Reaction
      1. Allergic Reaction (IgE mediated)
        1. Avoid all NSAIDs unless otherwise allowed via formal allergy evaluation
      2. Pseudoallergic reaction
        1. COX reaction, often associated with Asthma, Nasal Polyps, Allergic Rhinitis
        2. Assume true Allergic Reaction first and do not retrial with any NSAID until allergy evaluation
      3. Intollerance to side effect
        1. Distinguish and offer counter measures or alternative NSAID

Anti-Inflammatory Agents, Non-Steroidal (C0003211)

Definition (MSH) Anti-inflammatory agents that are non-steroidal in nature. In addition to anti-inflammatory actions, they have analgesic, antipyretic, and platelet-inhibitory actions.They act by blocking the synthesis of prostaglandins by inhibiting cyclooxygenase, which converts arachidonic acid to cyclic endoperoxides, precursors of prostaglandins. Inhibition of prostaglandin synthesis accounts for their analgesic, antipyretic, and platelet-inhibitory actions; other mechanisms may contribute to their anti-inflammatory effects.
Definition (NCI_NCI-GLOSS) A group of drugs that decrease fever, swelling, pain, and redness.
Definition (NCI) Anti-inflammatory agents that are not steroids. In addition to anti-inflammatory actions, they have analgesic, antipyretic, and platelet-inhibitory actions. They are used primarily in the treatment of chronic arthritic conditions and certain soft tissue disorders associated with pain and inflammation. They act by blocking the synthesis of prostaglandins by inhibiting cyclooxygenase, which converts arachidonic acid to cyclic endoperoxides, precursors of prostaglandins. Inhibition of prostaglandin synthesis accounts for their analgesic, antipyretic, and platelet-inhibitory actions; other mechanisms may contribute to their anti-inflammatory effects. Certain NSAIDs also may inhibit lipoxygenase enzymes or phospholipase C or may modulate T-cell function. (MeSH)
Definition (CSP) agents that counteract or suppress inflammation and are not steroids; most have in addition analgesic, antipyretic, and platelet-inhibitory actions; they act by blocking the synthesis of prostaglandins by inhibiting cyclooxygenase, which converts arachidonic acid to cyclic endoperoxides, precursors of prostaglandins: inhibition of prostaglandin synthesis accounts for their analgesic, antipyretic, and platelet-inhibitory actions; other mechanisms may contribute to their anti-inflammatory effects.
