Pirfenex 400 Mg

Pirfenex 400 mg Tablet is a powerful pharmaceutical formulation specifically designed for patients suffering from Idiopathic Pulmonary Fibrosis (IPF). This progressive, chronic condition causes irreversible scarring in the lungs, which leads to breathlessness and a decrease in oxygen transfer to the bloodstream. a medication that has become a cornerstone in IPF treatment due to its anti-fibrotic and anti-inflammatory properties. With its higher strength per tablet (400 mg), this formulation is especially useful in reducing daily pill burden and enhancing patient compliance.

The 400 mg dosage strength allows for fewer tablets per day compared to the lower-strength variants, making it ideal for long-term management of IPF in patients requiring higher daily doses. Pirfenex 400 mg has improved the lives of many by offering relief from symptoms, slowing disease progression, and giving patients better control over their respiratory health.

Understanding Idiopathic Pulmonary Fibrosis (IPF)

IPF is a rare yet serious condition characterized by chronic, progressive lung scarring (fibrosis) of unknown origin. The lung tissue becomes thick and stiff, preventing the lungs from functioning efficiently. Over time, this leads to shortness of breath, chronic cough, reduced stamina, and eventually respiratory failure.

As IPF progresses, the lungs lose their ability to efficiently transfer oxygen to the blood. The disease severely impacts a person’s quality of life, often limiting physical activities and independence. There is currently no cure for IPF, but early and effective treatment with medications like Pirfenex can significantly slow disease progression and improve symptoms.

What is Pirfenex 400 mg?

Pirfenex 400 mg contains Pirfenidone, a medication proven to slow the scarring process in IPF. It helps protect lung function over time and reduces the rapid decline seen in untreated patients. Pirfenidone works by targeting various biological pathways that contribute to fibrosis and inflammation.

The 400 mg strength formulation offers a convenient way to meet the full daily dosage requirement with fewer tablets, which makes it easier for patients to maintain adherence and consistency in treatment.

How Pirfenex 400 mg Works

Pirfenidone, the active ingredient in Pirfenex 400 mg, has a dual-action mechanism:

1. Anti-fibrotic Action: It suppresses the activity of pro-fibrotic growth factors such as transforming growth factor-beta (TGF-β), which are responsible for the abnormal build-up of fibrous tissue in the lungs.

2. Anti-inflammatory Action: It also inhibits the production of inflammatory mediators like tumor necrosis factor-alpha (TNF-α), which contribute to chronic inflammation and further tissue damage.

By addressing both fibrosis and inflammation, Pirfenex 400 mg slows the progression of IPF, helping patients breathe better and retain lung function for a longer duration.

Indications

Pirfenex 400 mg is indicated for:

• Idiopathic Pulmonary Fibrosis (IPF) – to reduce disease progression, delay lung function deterioration, and improve the patient’s ability to perform daily activities.

It may also be explored for use in fibrotic interstitial lung diseases and other lung disorders associated with fibrosis under medical supervision, although these uses are considered off-label.

Dosage and Administration

Standard Dosage for IPF:

• The total recommended daily dose is 2400 mg of Pirfenidone, divided into three doses of 800 mg each.

• Using the 400 mg strength, patients typically take two tablets (800 mg) three times daily, with meals.

Dose Titration (Initial Week of Therapy):

• Week 1: One 400 mg tablet, three times a day

• Week 2: Two 400 mg tablets (800 mg), three times a day

• Week 3 and onward: Full dose, three doses of 800 mg daily (i.e., six 400 mg tablets/day)

Administration Tips:

• Always take Pirfenex with food to reduce the risk of nausea and stomach discomfort.

• Swallow the tablets whole with water. Do not chew, crush, or break them.

• Try to take doses at consistent times daily to maintain steady blood levels.
