Pirfenidone in the treatment of idiopathic pulmonary fibrosis: an evidence-based review of its place in therapy

Abstract

The landscape of idiopathic pulmonary fibrosis (IPF) has changed. The significant progress regarding our knowledge on the pathogenesis of the disease together with the experience achieved after a series of negative trials has led to the development of two drugs for the treatment of IPF. Both pirfenidone and nintedanib can slow significantly the rate of disease progression. They are safe with side effects that can be either prevented by close collaboration between health care professionals and patients or treated successfully when they occur, rarely leading to treatment discontinuation. However, there are still few unanswered questions regarding the application of the beneficial results of pharmaceutical trials in the general population of IPF patients. Long-term "real-life" studies are being undertaken to answer these questions. In this article, we focus on the advances that have led to the development of the antifibrotic agents with particular focus on pirfenidone.
