After pirfenidone and nintedanib showed efficacy, drug treatment for idiopathic pulmonary fibrosis began to focused on anti-fibrosis. Current research on idiopathic pulmonary fibrosis mainly focus on the pathogenesis and therapeutic targets, and more targeted drugs are gradually entering clinical trials. This article summarizes the results of recent studies on the treatment of idiopathic pulmonary fibrosis with pirfenidone and nintedanib alone or in combination by searching the literature, and reviews the mechanism and test results of the new target anti-fibrosis drugs based on molecular biology that are currently undergoing clinical research in various phases, and aims to provide a basis for how to choose drugs to treat idiopathic pulmonary fibrosis.
