What is Esbriet used for?
Esbriet contains pirfenidone as the active ingredient and is used for the treatment of idiopathic pulmonary fibrosis (IPF), a lung disease. IPF is a condition where scar tissue is formed deep within the lungs. This scar tissue over time becomes thicker and more rigid making it more difficult for the lungs to work properly and harder for you to breathe. The lack of oxygen caused by this affects how other organs function in your body causing other medical complications. Exactly what causes IPF is not known, but the disease is progressive and can be life-threatening. Esbriet will slow the progression of the disease but will not cure IPF.
Pirfenidone belongs to a class of medications called pyridones. Pirfenidone’s mechanism of action is thought to be through reducing lung scarring, by reducing the production of growth factors and procollagens I and II. (Procollagens are used to produce collagen, a protein that usually adds strength and support to many body tissues). The exact mechanism of action for pirfenidone in treating IPF is not fully understood.
How often should Esbriet be taken?
Esbriet is available as tablets: 267 mg, and 801 mg, and as capsules: 267 mg.
Esbriet is started on a dose of one capsule or tablet a day on the first week of treatment. It is gradually increased weekly by one tablet or capsule a week until you are taking one capsule or tablet three times a day. Esbriet is taken with food.
