NSAIDS

NSAIDs (Non-Steroidal Anti-Inflammatory Drugs)

• NSAIDs are medications that help to reduce pain and inflammation.

• Mechanism of Action:
    - NSAIDs work by inhibiting the enzyme cyclooxygenase (COX) and thereby reducing the levels of prostaglandin E2 (PGE(2)) in the hypothalamus.
    - Prostaglandins are chemicals produced by injured cells that cause inflammation and swelling.

Clinical Indications

• NSAIDs are indicated for:
    - Mild-to-moderate pain relief
    - Reducing inflammation
    - Treating fever (pyrexia)

• Common uses include musculoskeletal pain, nerve pain, and neurological pain.
  

Examples of NSAIDs

• Ibuprofen (Motrin, Advil)

• Acetaminophen (Tylenol)

• Aspirin (ASA)

Antipyretics

• Antipyretics are medications commonly found in over-the-counter (OTC) cough and cold products.

• Important to ensure that patients are not doubling up on antipyretic medications, as this could lead to excessive dosing.

Administration Considerations

• Administration with food or milk is recommended to minimize gastric upset.

• Monitoring:
    - Evaluate pain levels 30–60 minutes after administration.
    - Monitor Blood Urea Nitrogen (BUN) and serum creatinine to assess renal function.

Side Effects/Adverse Effects

• Common side effects and adverse effects include:
    - Gastrointestinal distress (nausea, vomiting, diarrhea, constipation)
    - Liver damage
    - Kidney dysfunction
    - Heartburn
    - Heavier menstrual cycles
    - Dark tarry stools, indicating possible gastrointestinal bleeding
    - Skin conditions (e.g., ecchymosis, purpura)
    - Increased cardiovascular effort
    - Tinnitus and vertigo

Lab Values to Monitor

• Important lab values include:
    - Serum creatinine
    - Blood Urea Nitrogen (BUN)
    - Aspartate Aminotransferase (AST)
    - Alanine Aminotransferase (ALT)
    - Complete Blood Count (CBC)
    - Procalcitonin (PCT)

Contraindications

• NSAIDs should be avoided in patients with:
    - Hepatic and renal disease
    - Active gastrointestinal ulcers

Precautions

• Certain precautions must be taken when administering NSAIDs:
    - Risk of gastrointestinal irritation
    - Potential for raised blood pressure
    - Breathing difficulties
    - Weight changes (gain or loss)
    - Risk of toxicity

Drug Interactions

• NSAIDs can interact with the following medications:
    - Blood thinners
    - Antihypertensives
    - Diuretics
    - Selective Serotonin Reuptake Inhibitors (SSRIs) / Antidepressants
    - Alcohol
    - Use of multiple NSAIDs

Nursing Assessment

Pre-assessment

• Evaluate the following:
    - Pain level
    - Medical history
    - Cardiovascular status
    - Liver and kidney function
    - Current medication use (including OTC)

Post-assessment

• Monitor for:
    - Effectiveness of pain relief
    - Gastrointestinal symptoms
    - Elevated blood pressure
    - Signs of bleeding
    - Liver and kidney function

Nursing Considerations

• Focus on:
    - Preventing and assessing for gastrointestinal bleeding
    - Assessing for nephrotoxicity
    - Monitoring for cardiovascular complications
    - Observing for fluid retention and edema

Patient Teaching

• Educate patients on the following:
    - Taking NSAIDs with food or milk to reduce gastrointestinal irritation.
    - Avoiding the concurrent use of multiple oral NSAIDs, including OTC products.
    - Reporting any adverse symptoms such as black and tarry stools, vomiting blood, experiencing new swelling or weight changes.
    - Not to use OTC NSAIDs for more than 10 consecutive days without consultation.
    - Avoid use during the last 6-8 weeks of pregnancy.

Safety Considerations

• Strategies to minimize risks include:
    - Limiting the use of NSAIDs to prevent gastrointestinal damage, kidney damage, and cardiovascular events.
    - Avoiding use in patients with active stomach ulcers.
    - Exercising caution when combining with other medications, including OTC products.

Additional Notes

• Aspirin should not be given to individuals under 18 years of age due to the risk of Reye syndrome; acetaminophen is a safer alternative.

• Chewing aspirin should be instructed only during heart attack emergencies to facilitate rapid absorption in the bloodstream.
