Drug Description


Esbriet is a proven pharmaceutical treatment for idiopathic pulmonary fibrosis (IPF), a respiratory condition characterized by the formation of fibrous tissue in the lungs. This fibrous tissue gradually thickens and stiffens, impairing lung function and causing respiratory distress. The reduced oxygen supply to vital organs, such as the brain and heart, can result in various associated medical complications. While the exact cause of IPF is unknown, the disease is progressive and can be life-threatening. 

Note that Esbriet does not offer a curative approach for IPF. However, this pharmaceutical agent demonstrates the potential to decelerate the progression of the disease, thereby providing valuable therapeutic benefits. 

Uses and Dosage 

Pirfenidone is a pharmacological agent indicated for treating IPF, a specific lung disorder characterized by the formation of scar tissue and subsequent lung stiffness, leading to respiratory difficulties. Pirfenidone is known to mitigate the progression of IPF potentially, thus offering a therapeutic benefit. 

Various factors, including your medical condition, response to treatment, and concurrent medication usage, determine the appropriate dosage of pirfenidone. Inform your healthcare provider and pharmacist about all the products you are currently using, encompassing both prescription and nonprescription drugs and herbal products. 

This medication should be administered orally with food, following your doctor’s instructions, typically three times a day. Taking pirfenidone alongside a meal has been associated with potentially reducing dizziness and nausea. To minimize the risk of adverse effects, your doctor may recommend initiating and gradually increasing treatment with a low dose. Adhere diligently to your doctor’s instructions throughout treatment.
