[Respimat®, first Soft Mist™ inhaler: new perspectives in the management of COPD]

Abstract

Introduction: In COPD, inhaler choice should be based on the likelihood that the patient will be able to use the device correctly in order to favour adherence and compliance, and therefore treatment efficacy. SATE OF THE ART: Performances of usual inhalers are limited by the necessity of a good coordination of patient inspiration and inhaler activation (pressurized metered dose inhalers), or a sufficient inspiratory flow (dry powder inhalers). Respimat®, the first "Soft Mist™ inhaler" (SMI), releases the drug solution as a low and sustained soft mist, so that lung deposition is both improved and reproducible.

Perspectives: In clinical studies, Respimat® has been shown to allow equivalent bronchodilator response and tolerability to metered dose or dry powder inhalers, but with lower doses of active drugs. Furthermore, studies assessing inhaler preference in COPD showed that patients preferred Respimat® to usual inhalers.

Conclusion: Respimat® SMI offers new perspectives for the management of chronic respiratory diseases, particularly in newly diagnosed or poorly compliant patients.
