Each film coated tablet contains Roflumilast INN 500 mcg.


Roflumilast is an anti-inflammatory medicine called selective phosphodiesterase 4 inhibitor. Roflumilast reduces the activity of phosphodiesterase 4, a protein occurring naturally in body cells. When the activity of this protein is reduced, there is less inflammation in the lungs. This helps to stop narrowing of airways due to inflammation in chronic obstructive pulmonary disease (COPD). Thus Roflumilast eases breathing.


Roflumilast is used to treat asthma and COPD in adults. Roflumilast is to be used in addition to bronchodilators in asthma and COPD patients.
