Roflumilast

Roflumilast (trade name Daxas) is a medication used to treat chronic obstructive pulmonary disease (COPD). It is a phosphodiesterase-4 inhibitor that is designed to reduce inflammation in the lungs, making it easier for people with COPD to breathe. Roflumilast was approved by the US Food and Drug Administration (FDA) in 2011 and is currently available in tablet form. It is usually taken once daily, with or without food. Common side effects include nausea, headache, and diarrhea. Roflumilast should not be used in people with severe liver or kidney problems.
