Medications for Pleuritis
For uncomplicated viral or nonspecific pleuritis, NSAIDs are the primary treatment for pain management, while treatment of complicated pleural infections requires antibiotics plus drainage procedures with consideration of combination TPA and DNAse for residual collections. 1, 2
Treatment Algorithm Based on Pleuritis Type
Uncomplicated Pleurisy (Viral or Nonspecific)
NSAIDs are the mainstay of pain management once life-threatening causes (pulmonary embolism, myocardial infarction, pericarditis, aortic dissection, pneumothorax) have been excluded through history, physical examination, chest radiography, and ECG. 1, 2 This applies after ruling out serious etiologies, as viruses (Coxsackieviruses, RSV, influenza, parainfluenza, mumps, adenovirus, CMV, EBV) are common causative agents. 1
Complicated Pleural Infection (Empyema/Parapneumonic Effusion)
The treatment approach is more complex and medication-focused:
Initial Management
- Antibiotics are essential for all pleural infections (specific agents depend on culture results and local resistance patterns)
- Small bore chest tube drainage (14F or smaller) should be the initial drainage method 3
For Residual Collections After Initial Drainage
Combination TPA and DNAse should be considered when initial chest tube drainage has ceased but leaves a residual pleural collection. 3 The evidence shows this combination:
- Reduces length of hospital stay
- Reduces likelihood of persistent fevers
- Increases improvements in chest x-ray opacification
- However, may increase risk of complications (serious and non-serious) 3
Dosing regimen:
- Standard: 10 mg TPA twice daily + 5 mg DNase twice daily for 3 days
- Alternative (if higher bleeding risk): 5 mg TPA twice daily + 5 mg DNase twice daily for 3 days
- Patient consent is mandatory due to bleeding risk 3
What NOT to Use
- Single agent TPA or DNAse alone: Do not improve clinical outcomes 3
- Streptokinase: Should not be used—increases post-treatment complications with no mortality benefit, no reduction in hospital stay, and no reduction in need for surgery 3
- Urokinase: May reduce need for surgery and hospital stay, but is not the preferred agent compared to TPA/DNAse combination 3
Alternative for Non-Surgical Candidates
Saline irrigation (250 mL three times daily) can be considered when TPA/DNAse therapy or surgery is not suitable, as it may reduce the need for thoracic surgery. 3
Important Caveats
- In patients over 50 years with pneumonia, smokers, or those with persistent symptoms, document radiographic resolution with repeat chest x-ray at 6 weeks 1
- The choice between medical and surgical management depends on clinical context—ACCP criteria favor higher sensitivity (fewer missed cases requiring drainage), while BTS 2003 criteria favor higher specificity (avoiding unnecessary procedures in frail/elderly patients) 4
- For tuberculous pleuritis specifically, standard anti-tuberculosis therapy is required, though diagnosis remains challenging with conventional tests 5
