目的:为临床合理使用罗氟司特治疗慢性阻塞性肺疾病(COPD)提供参考。方法:查阅近年来国内外相关文献,对罗氟司特治疗COPD的药效学、药动学、药物相互作用、临床有效性和安全性等方面的进展进行归纳和总结。结果:罗氟司特具有强大的抗炎作用和中等程度的支气管扩张作用,可以有效改善肺功能,显著降低中/重度COPD患者的平均恶化率,预防急性加重;其活性代谢产物N-氧化物(RNO)在体内可以逆转糖皮质激素依赖,单用或与糖皮质激素联用均能发挥强大的抗炎效应,且不增加COPD患者严重不良心血管事件的发生率。结论:在充分评估患者严重程度和急性加重风险的基础上,罗氟司特联合支气管扩张剂治疗能使患者获益,但尚需进一步开展国际性、大规模、多中心综合临床研究。 相似文献

Patients with chronic obstructive pulmonary disease (COPD) and chronic bronchitis have a reduction in lung function and a higher risk of suffering exacerbations, which result in a deterioration in their quality of life, an accelerated progression of the disease and a greater mortality. COPD is currently considered an inflammatory disease involving airways and lung parenchyma. The symptoms that are typical of chronic bronchitis (chronic cough and sputum production) are markers of underlying inflammation, characteristic of COPD. Roflumilast, an antiinflammatory drug that belongs to the new therapeutic class of phosphodiesterase PDE4 inhibitors, is the first drug developed for the treatment of a specific phenotype of COPD (COPD associated with chronic bronchitis). The results of clinical trials indicated that in patients with COPD associated with chronic bronchitis and a history of exacerbations, roflumilast improves lung function and reduces the frequency of exacerbations that require medical interventions. This effect remained when it was added to a regular treatment with long-acting bronchodilators such as tiotropium or long-acting β?-adrenoceptor agonists (LABAs) such as salmeterol. Roflumilast has been shown to be generally well tolerated. Side effects were typically mild to moderate and included diarrhea, nausea, weight decrease and headache. Gastrointestinal side effects mainly occurred within the first weeks of therapy and mostly resolved on continued treatment. 相似文献

Roflumilast is a selective phosphodiesterase (PDE) 4 inhibitor with a range of anti-inflammatory properties and potential for treatment of inflammatory disease. The therapeutic effects of roflumilast are thought to be mediated via increased levels of cellular 3',5'-cyclic adenosine monophosphate (cAMP) and include inhibition of microvascular leakage, inhibition of trafficking, release of cytokines and chemokines from inflammatory cells, and bronchodilation. The anti-inflammatory and bronchodilator properties of roflumilast have resulted in clinical studies to investigate the effects of roflumilast in inflammatory airway diseases such as asthma and chronic obstructive pulmonary disease. In asthma, roflumilast taken as a once-daily oral dose of 500 ug has been shown to improve clinical symptoms and airway function, reduce exercise-induced asthma and decrease bronchial airway hyperresponsiveness. In chronic obstructive pulmonary disease, roflumilast taken as a once-daily oral dose of 500 ug has been shown to reduce the frequency of exacerbations with small effects on improving lung function. Side effects of roflumilast appear to be mild and short lasting. It is likely that this new class of selective PDE4 inhibitor may provide a therapeutic option for patients with inflammatory airway disease. 相似文献

Chronic obstructive pulmonary disease (COPD) is a progressive disease of the airways that is triggered primarily by smoking. It manifests clinically with dyspnea, cough and sputum production, all of which become aggravated with disease progression. The only intervention that can halt the decline in lung function in COPD is smoking cessation--other interventions and therapeutic treatments can only slow down the progression of the disease. Pharmacologic treatment of stable COPD consists primarily of bronchodilators, which are used for relieving symptoms and reducing lung function decline, and corticosteroids, which are used for minimizing the associated inflammation. Methylxanthines are non-selective phosphodiesterase (PDE) inhibitors with bronchodilatory and anti-inflammatory effects; however, their use in COPD and other respiratory conditions is limited by their narrow therapeutic index and poor safety profile. Cilomilast and roflumilast are selective PDE4 inhibitors that are currently in pre-registration and phase III clinical trials, respectively, for the treatment of COPD (cilomilast and roflumilast) and asthma (roflumilast). 相似文献
