Pirfenidone 200 mg (Pirfenex)

Introduction

Pirfenidone 200 mg is a prescription medicine widely used for the treatment of idiopathic pulmonary fibrosis (IPF). This chronic lung condition causes progressive scarring of lung tissue, leading to breathing difficulties. Pirfenidone 200 mg helps slow disease progression and supports better lung function when used consistently.

What is Pirfenidone 200 mg?

Pirfenidone 200 mg is an oral antifibrotic and anti-inflammatory medication. It is marketed under the brand name Pirfenex. The medicine works by reducing fibrosis and inflammation in lung tissue. Pirfenidone 200 mg does not cure IPF, but it plays a vital role in managing the condition effectively.

Uses of Pirfenidone 200 mg

Pirfenidone 200 mg is primarily prescribed for:

• Idiopathic pulmonary fibrosis

• Slowing lung tissue scarring

• Improving lung function stability

• Reducing decline in forced vital capacity (FVC)

Pirfenidone 200 mg is not used for asthma or other acute lung infections.

How Pirfenidone 200 mg Works

Pirfenidone 200 mg works by inhibiting the production of fibrotic growth factors and inflammatory mediators. These substances are responsible for excessive collagen formation in the lungs. By limiting fibrosis, Pirfenidone 200 mg helps preserve lung elasticity and improves oxygen exchange over time.

Dosage and Administration

The dosage of Pirfenidone 200 mg is decided by a healthcare professional based on patient tolerance and disease severity.

Typical dosage schedule includes:

• Initial phase: Gradual dose escalation

• Maintenance dose: 200 mg taken three times daily
