From the Guidelines
Management of idiopathic pulmonary fibrosis (IPF) requires a multidisciplinary approach focusing on slowing disease progression, managing symptoms, and improving quality of life, with the use of antifibrotic medications such as pirfenidone and nintedanib, as recommended by the most recent guidelines 1. The diagnosis of IPF is confirmed through high-resolution CT showing usual interstitial pneumonia pattern, pulmonary function tests showing restrictive pattern with reduced diffusion capacity, and sometimes lung biopsy.
- Two antifibrotic medications are FDA-approved for IPF: pirfenidone (801 mg three times daily) and nintedanib (150 mg twice daily), which slow lung function decline but don't reverse existing fibrosis, as supported by recent studies 1.
- Supportive care includes:
- Supplemental oxygen when oxygen saturation falls below 88%
- Pulmonary rehabilitation to improve exercise capacity
- Vaccination against respiratory infections
- Symptom management with opioids for refractory dyspnea and cough suppressants
- Comorbidities like gastroesophageal reflux should be treated with proton pump inhibitors, as recommended by recent guidelines 1.
- Lung transplantation should be considered for appropriate candidates with progressive disease.
- Regular monitoring includes pulmonary function tests every 3-6 months, 6-minute walk tests, and oxygen assessment.
- Early referral to palliative care is recommended as IPF has a poor prognosis with median survival of 3-5 years from diagnosis, as noted in recent studies 1. These interventions aim to preserve lung function and improve quality of life as the underlying pathophysiology involves abnormal wound healing and progressive scarring of lung tissue. It is essential to note that corticosteroid therapy is no longer an option for the treatment of IPF, except to alleviate incapacitating cough or to treat acute exacerbation of IPF, as stated in previous guidelines 1. The most recent and highest quality study 1 provides the basis for the current management approach, and its recommendations should be followed to ensure the best possible outcomes for patients with IPF.
From the FDA Drug Label
Pirfenidone is indicated for the treatment of idiopathic pulmonary fibrosis (IPF). The recommended daily maintenance dosage of pirfenidone is 801 mg three times daily for a total of 2,403 mg/day. Upon initiation of treatment, titrate to the full dosage of 2,403 mg/day over a 14-day period as follows: * Days 1 through 7: 267 mg three times daily (801 mg/day) * Days 8 through 14: 534 mg three times daily (1,602 mg/day) * Days 15 onward: 801 mg three times daily (2,403 mg/day) Consider temporary dosage reduction, treatment interruption, or discontinuation for management of adverse reactions. Prior to treatment, conduct liver function tests.
The management and treatment approach for Idiopathic Pulmonary Fibrosis (IPF) involves the use of pirfenidone with a recommended daily maintenance dosage of 801 mg three times daily for a total of 2,403 mg/day. The treatment should be initiated with a 14-day titration period to reach the full maintenance dosage.

Management and Treatment Approach for Idiopathic Pulmonary Fibrosis (IPF)
The management and treatment approach for IPF involves a multi-faceted strategy to slow disease progression, improve quality of life, and extend life expectancy. Key components of this approach include:
- Pharmacological therapy with anti-fibrotic drugs, such as nintedanib and pirfenidone, which have been shown to reduce decline in lung function in patients with IPF 3, 4, 5
- Treatment of comorbidities, such as gastro-esophageal reflux and pulmonary hypertension, to improve overall health and reduce symptoms 3, 6, 7
- Symptom relief, including management of dyspnea and cough, to improve quality of life 3, 7
- Pulmonary rehabilitation, which can help improve exercise tolerance and reduce symptoms 3, 6, 7
- Palliative care, which focuses on relieving symptoms and improving quality of life for patients with advanced disease 3, 6, 7
- Patient education, which enables patients to make informed decisions about their care and manage their disease and treatment side effects effectively 3
Pharmacological Options
Current pharmacological options for IPF include:
- Nintedanib, which has been shown to slow disease progression and improve quality of life 5
- Pirfenidone, which has been shown to reduce decline in lung function and improve survival 4, 7
- Emerging pharmacological options, including combination therapies and new anti-fibrotic agents, which are being investigated in clinical trials 6
Future Directions
The future of IPF management is likely to involve a more personalized approach, with treatment tailored to individual patient needs and characteristics. This may include:
