Both these drugs pirfenidone and nintedanib available in the market since long time for treatment for fibrosis or lungs scarring
My question is which one is more effective in reducing lungs scarring pirfenidone or nintedanib based on long terms clinical trial
there is lots of literature available in google but very confusing as far as pro and cons and cost benefits in reducing or at least stopping the progression of lungs scarring is concern
