Abstract

BACKGROUND: Nasal sprays with corticosteroids deliver medication to the restricted areas including anterior and inferior parts of the nasal cavity. The fluticasone exhalation delivery system (EDS-FLU) has recently been proved to improve care by increasing superior/posterior intranasal corticosteroid deposition.

OBJECTIVE: This study aims to evaluate the efficacy of EDS-FLU in patients with chronic rhinosinusitis with nasal polyps (CRSwNP).

METHODOLOGY: A systematic literature review using Pubmed, Embase, Cochrane Library, and Web of Science was conducted to identify studies assessing the effect of EDS-FLU on outcomes in patients with CRSwNP.

RESULTS: Of the initial 108 abstracts reviewed, 4 full-text articles were included. The 22-item sinonasal outcome test scores were significantly decreased in patients with CRSwNP after receiving EDS-FLU twice a day (93, 186, or 372 μg) for 16 weeks when compared with exhalation delivery system (EDS)-placebo (all P < .001). Patients with CRSwNP reported significant improvement of smell after receiving twice daily EDS-FLU twice a day (93, or 372 μg) for 4 weeks when compared with EDS-placebo (all P < .05). The proportions of patients achieving ≥1-point improvement in total polyp grade were significantly higher in EDS-FLU group and dose dependent, with the highest rates in the 372 μg group. The proportions of patients achieving polyp elimination were significantly higher in EDS-FLU group with the highest rates in the 372 μg group.…

How strong is the evidence?
