What is the best NSAID (Non-Steroidal Anti-Inflammatory Drug) for a patient with hypertension (High Blood Pressure)?

Best NSAID for Hypertensive Patients

Acetaminophen (paracetamol) is the preferred first-line analgesic for patients with hypertension, as it has minimal effects on blood pressure compared to traditional NSAIDs. 1, 2

Impact of NSAIDs on Blood Pressure

• All NSAIDs can elevate blood pressure by approximately 5 mmHg through mechanisms including sodium retention, water retention, and vasoconstriction 3, 2
• NSAIDs can blunt the effects of most antihypertensive medications, particularly ACE inhibitors, ARBs, and diuretics 4
• Patients with treated hypertension may experience BP increases ranging from 1-14 mmHg when taking NSAIDs 2

NSAID Selection Algorithm for Hypertensive Patients

First-Line Option:

• Acetaminophen (paracetamol) - up to 3000 mg/day in divided doses 1
  • Has minimal effects on blood pressure compared to traditional NSAIDs
  • Monitor for hepatic toxicity with long-term use

If Acetaminophen is Ineffective:

For Short-Term Use (≤5 days):

1. Naproxen at lowest effective dose (e.g., 220-375 mg twice daily) 5, 6
   • Has shown smaller BP increases compared to some other NSAIDs
   • Still requires BP monitoring

For Patients Requiring Anti-Inflammatory Effects:

1. Topical NSAID preparations when appropriate for localized pain 1
   • Minimizes systemic absorption and cardiovascular effects

For Patients with Concurrent Anticoagulation:

• Avoid all NSAIDs if possible due to increased bleeding risk 1, 5

Monitoring Recommendations

• Check blood pressure within 1-2 weeks of starting any NSAID 1
• Monitor renal function, especially in patients taking ACE inhibitors, ARBs, or diuretics 1
• Use NSAIDs at the lowest effective dose for the shortest duration possible 1

Important Precautions

• Avoid NSAIDs in patients with:

  • Uncontrolled hypertension 1
  • Heart failure 1
  • Chronic kidney disease 1
  • Concurrent use of anticoagulants when possible 1, 5

• Calcium channel blockers may be the preferred antihypertensive medication class when NSAID use is unavoidable, as they appear to maintain their effectiveness better than other classes 2

• Discontinue NSAIDs if:

  • Blood pressure increases significantly
  • Renal function worsens (BUN or creatinine doubles)
  • Signs of fluid retention develop 1

Special Considerations

• Elderly patients are at higher risk for NSAID-induced hypertension and should be monitored more closely 3
• Patients with pre-existing cardiovascular disease should avoid NSAIDs when possible 1
• The risk of NSAID-induced hypertension must be balanced against the expected benefit of treatment 3
