Pericarditis Treatment Guidelines

Introduction to Pericarditis Management

• The European Society of Cardiology recommends ibuprofen as the preferred NSAID for pericarditis treatment due to its superior safety profile and favorable impact on coronary flow 1, 2
• Indomethacin should be avoided in elderly patients because it reduces coronary blood flow, posing a particular risk in this population 1, 2

First-Line Treatment

• The European Society of Cardiology guidelines suggest that NSAIDs plus colchicine is the recommended first-line combination for acute pericarditis 3
• Aspirin 750-1000 mg every 8 hours or ibuprofen 600 mg every 8 hours (preferred) should be used for 1-2 weeks with gastroprotection 3
• Colchicine should be added at weight-adjusted doses: 0.5 mg once daily if <70 kg or 0.5 mg twice daily if ≥70 kg for 3 months 3

NSAID Selection and Dosing

• Ibuprofen is the preferred NSAID due to its wide dose range (600 mg every 8 hours, range 1200-2400 mg/day) and superior safety profile 1, 2, 3
• Indomethacin dosing is 25-50 mg every 8 hours (75-150 mg/day total), starting at the lower end to avoid headache and dizziness 4, 5, 6

Tapering Strategy

• NSAIDs should be tapered gradually: decrease aspirin by 250-500 mg every 1-2 weeks or ibuprofen by 200-400 mg every 1-2 weeks 6, 7, 3
• Indomethacin should be decreased by 25 mg every 1-2 weeks 6, 7
• Tapering should only be attempted when symptoms are absent and CRP is normal 3

Special Considerations

• The European Society of Cardiology guidelines explicitly state that ibuprofen is preferred over indomethacin, with a consistent recommendation for NSAIDs as Class I, Level B evidence for pericarditis treatment 1, 2, 4, 5
• Colchicine plus NSAIDs reduces recurrence (OR 0.37; 95% CI 0.27-0.51) 3
• Indomethacin may be considered in younger patients without coronary disease when ibuprofen or aspirin are contraindicated or not tolerated 4, 5

Critical Pitfalls to Avoid

• Indomethacin should not be used as first-line in elderly patients or those with coronary artery disease due to coronary flow reduction 1, 2
• NSAIDs should not be used alone without colchicine, as this increases recurrence risk 3
• Treatment should not be stopped prematurely before CRP normalization, as inadequate treatment duration is the most common cause of recurrence 3, 8
