Fluticasone nasal sprays are common treatment options for patients with rhinitis. Therefore, we aimed to investigate the effects of fluticasone nasal spray on patients with both CR and COPD. Methods: A retrospective review was performed using data from former smokers with CR and COPD at China Medical University Hospital (CMUH). Based on their medication history, patients were allocated into Group A, who had received treatment with fluticasone nasal spray, and Group B, who had never received this treatment. Pulmonary function test results, including forced expiratory volume in 1 s (FEV1) and forced vital capacity (FVC), were collected for both groups before treatment and one year after treatment. Statistical analysis was performed to evaluate the impact of fluticasone nasal spray treatment on pulmonary function. Results: A total of 123 former smokers were included, with 62 patients in Group A and 61 patients in Group B. At baseline, there was no significant difference in age, sex, and pulmonary function between the two groups. After one year of treatment, Group A showed an upward trend in pulmonary function, with the FEV1 increasing from 1.613 \u00b1 0.554 to 1.708 \u00b1 0.675 (p &lt; 0.05) and the FVC increasing from 2.540 \u00b1 0.694 to 2.670 \u00b1 0.839 (p &lt; 0.05). On the other hand, Group B exhibited a downward trend in pulmonary function after one year, with the FEV1 decreasing from 1.609 \u00b1 0.554 to 1.544 \u00b1 0.517 (p &lt; 0.05) and the FVC decreasing from 2.586 \u00b1 0.665 to 2.495 \u00b1 0.679 (p &lt; 0.05). Conclusions: This retrospective study suggests that the combined use of fluticasone nasal spray may be associated with improved pulmonary function in former smokers with both CR and COPD. This finding supports the concept of \u201cunited airway disease\u201d.<\/jats:p>","DOI":"10.3390\/jcm14113637","type":"journal-article","created":{"date-parts":[[2025,5,22]],"date-time":"2025-05-22T08:49:57Z","timestamp":1747903797000},"page":"3637","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["The Effect of Fluticasone Nasal Spray on Patients with Chronic Rhinitis and Chronic Obstructive Pulmonary Disease"],"prefix":"10.3390","volume":"14","author":[{"given":"Zheng-Yan","family":"Dai","sequence":"first","affiliation":[{"name":"Department of Otorhinolaryngology-Head and Neck Surgery, China Medical University Hospital, Taichung 404327, Taiwan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yu-Ting","family":"Li","sequence":"additional","affiliation":[{"name":"Department of Otorhinolaryngology-Head and Neck Surgery, China Medical University Hospital, Taichung 404327, Taiwan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0009-0007-4214-9304","authenticated-orcid":false,"given":"Jin-Yi","family":"Lin","sequence":"additional","affiliation":[{"name":"Department of Otorhinolaryngology-Head and Neck Surgery, China Medical University Hospital, Taichung 404327, Taiwan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Chien-Lin","family":"Liu","sequence":"additional","affiliation":[{"name":"Department of Otorhinolaryngology-Head and Neck Surgery, China Medical University Hospital, Taichung 404327, Taiwan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yung-An","family":"Tsou","sequence":"additional","affiliation":[{"name":"Department of Otorhinolaryngology-Head and Neck Surgery, China Medical University Hospital, Taichung 404327, Taiwan"},{"name":"Department of Otorhinolaryngology-Head and Neck Surgery, Asia University Hospital, Taichung 404327, Taiwan"},{"name":"School of Medicine, China Medical University, Taichung 404328, Taiwan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5788-6821","authenticated-orcid":false,"given":"Chia-Der","family":"Lin","sequence":"additional","affiliation":[{"name":"Department of Otorhinolaryngology-Head and Neck Surgery, China Medical University Hospital, Taichung 404327, Taiwan"},{"name":"School of Medicine, China Medical University, Taichung 404328, Taiwan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8000-2350","authenticated-orcid":false,"given":"Chih-Jaan","family":"Tai","sequence":"additional","affiliation":[{"name":"Department of Otorhinolaryngology-Head and Neck Surgery, China Medical University Hospital, Taichung 404327, Taiwan"},{"name":"School of Medicine, China Medical University, Taichung 404328, Taiwan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3036-6156","authenticated-orcid":false,"given":"Liang-Chun","family":"Shih","sequence":"additional","affiliation":[{"name":"Department of Otorhinolaryngology-Head and Neck Surgery, China Medical University Hospital, Taichung 404327, Taiwan"},{"name":"Department of Otorhinolaryngology-Head and Neck Surgery, Asia University Hospital, Taichung 404327, Taiwan"},{"name":"School of Medicine, China Medical University, Taichung 404328, Taiwan"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2025,5,22]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1","DOI":"10.4193\/Rhin20.401","article-title":"European Position Paper on Rhinosinusitis and Nasal Polyps 2020","volume":"58","author":"Fokkens","year":"2020","journal-title":"Rhinology"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"819","DOI":"10.1164\/rccm.202301-0106PP","article-title":"Global Initiative for Chronic Obstructive Lung Disease 2023 Report: GOLD Executive Summary","volume":"207","author":"Celli","year":"2023","journal-title":"Am.
