What is pirfenidone, its price and availability

Pirfenidone is a chemical with broad-spectrum anti-fibrotic effects. It is mainly used as an anti-fibrotic drug. The main medical role of pirfenidone is to prevent and reverse fibrosis and scar formation. It can not only effectively treat idiopathic pulmonary fibrosis (IPF), reduce the production of collagen fibers, inhibit the expression of inflammatory mediators, reduce vascular permeability, but also reduce the accumulation of neutrophils and inflammatory cells, thus exerting significant anti-inflammatory and anti-fibrotic effects. In addition to IPF, pirfenidone has also shown broad application potential in phase II clinical studies in renal disease, hypertrophic cardiomyopathy, various neurofibromas, diabetes with renal disease, and uterine leiomyoma.

In terms of use, pirfenidone is usually provided in tablet form, and the dosage needs to be gradually increased according to the dose escalation principle. Since the concentration of pirfenidone in the blood will increase significantly when taken on an empty stomach, it is recommended that patients take it after meals to reduce the occurrence of adverse reactions. During the treatment process, doctors will dynamically monitor the patient's lung imaging changes to evaluate the efficacy of the drug.

However, it should be noted that pirfenidone also has some side effects, such as nausea, vomiting, fever, rash, and possible liver cell damage. Therefore, you need to be particularly careful during use and strictly follow the instructions of professional doctors. At the same time, this drug is contraindicated for patients who are allergic to any component of pirfenidone, patients with severe liver disease, pregnant and lactating patients, and patients with severe kidney disease or requiring dialysis treatment. Patients with mild or moderate hepatic impairment should also use it with caution and have their liver function checked regularly before and during use. In addition, because pirfenidone may cause severe photosensitivity reactions and long-term exposure to light may cause skin cancer, patients should pay special attention to avoid overexposure to the sun when using it.

Domestic pirfenidone is now officially launched in the Chinese market and has been included in the Class B reimbursement items of medical insurance. Its standard packaging is 63 tablets of 200 mg. After reimbursement, consumers pay about 1,500 yuan out-of-pocket. At the same time, India also has the supply of pirfenidone generics with more favorable prices, such as 200mg 150 tablets produced by the Indian company Cipla, which only costs about 650 yuan.
