Common Name | Roflumilast N-oxide |
---|
Description | Roflumilast N-oxide belongs to the class of organic compounds known as benzamides. These are organic compounds containing a carboxamido substituent attached to a benzene ring. Roflumilast N-oxide is an extremely weak basic (essentially neutral) compound (based on its pKa). Roflumilast N-oxide is a metabolite of roflumilast. It has antiinflammatory effects and is under development as an orally administered drug for the treatment of inflammatory conditions of the lungs such as asthma, and chronic obstructive pulmonary disease (COPD). Roflumilast (trade names Daxas, Daliresp) is a drug which acts as a selective, long-acting inhibitor of the enzyme PDE-4. |
