ABSTRACT
Introduction
In chronic obstructive pulmonary disease (COPD), inhaled long-acting antimuscarinic agents (LAMA) are effective maintenance therapies used across all severity stages of the disease. Most of them are administered via dry powder inhalers, but these devices require a potent inspiratory flow which cannot be effectively achieved by patients with advanced disease. In such patients, inhaled therapy via nebulization might be an option.
Areas covered
Revefenacin is a LAMA that was specifically formulated for once daily nebulization and which was authorized by the FDA as a maintenance therapy for COPD. In phase II and III clinical studies discussed in this review, revefenacin demonstrated its rapid onset of action and sustained effect on lung function on both a short- and long-term basis.
Expert opinion
Nebulized revefenacin with once daily use does not require any particular effort of administration and hence can be used by patients with severe airways obstruction or by those having milder cognitive deficits. Further studies are needed, however, to better document the long-term cardiovascular safety and its ability to reduce the exacerbation rate.
