Use

Roflumilast is taken orally and is metabolized by cytochrome oxidase P45(CYP)3A4 and CYP1A2 enzyme into N-oxide. Roflumilast N-oxides activity is only 2-3 times weaker than that of roflumilast, and it also has relatively high PDE-4 selectivity. 90% of PDE-4 inhibition in the body is achieved by roflumilast N-oxide, while the other 10% is achieved by the original drug. A daily 500ng oral dose of roflumilast for a healthy person will produce a free blood concentration of roflumilast N-oxide in 24 hours of about 1-2 nmolL-1, and its serum protein binding rate is about 97%. Smoking has little impact on roflumilasts pharmacokinetics. Roflumilast mostly affects inflammation cells related to asthma, including eosinophils, neutrophils, and mast cells. This drug can specifically affect a certain enzyme that participates in smooth muscle contraction, it can prevent cAMP decomposition, thus preventing the signal transduction for inflammatory reactions, and it is anti-inflammatory, giving it relatively good curative effects in clinically treating asthma and COPD. Roflumilast can also significantly extend the deterioration of respiratory symptoms while also dramatically increasing patients quality of life.
