Effects of inhaled furosemide on dyspnea and pulmonary function in people with COPD: A literature review.

Abstract

Purpose: To determine whether inhaled furosemide can be effectively used in patients with chronic obstructive pulmonary disease (COPD) to improve feelings of dyspnea and improve pulmonary function values.

Methods: This literature review was conducted using randomized control trials and a literature review in which the participants consisted of or included patients with COPD receiving inhaled furosemide as a potential treatment option for their dyspnea and low pulmonary function values.

Results: Searches in four databases and secondary sources using five key terms yielded 83 unduplicated articles. Ultimately, four studies, one of which was a literature review, were included which studied the short-term result of inhaled furosemide on dyspnea and pulmonary function values. All studies measured dyspnea as an outcome and three found a statistically significant improvement in patient reported symptoms. Pulmonary function values were measured in all studies which all found improvements.

Conclusion: The effect of inhaled furosemide on the dyspnea and pulmonary function values in people with COPD remains uncertain, and questions have emerged regarding the long-term impact on these patients. While this therapy is promising for dyspnea relief and improvement of pulmonary function values in people with COPD, further consideration and additional data still need to be gathered.
