Novel Method for Removal of Orally Deposited Inhaled Fluticasone Propionate (EVOOW)
26 augusti 2026 uppdaterad av: University of Wisconsin, Madison
A Proof-of-Concept Study of a Novel Method for Removal of Residual Oropharyngeal Inhaled Corticosteroid Deposits in Asthma
This study is to find out if an Extra Virgin Olive-Oil-based Water (EVOOW) mix, removes more Fluticasone Propionate (FP) from the mouth than Water alone.
2 strengths of the EVOOW mix will be tested, one with equal parts EVOO and Water (50/50) and one with 3 parts EVOO and 1 part Water (75/25).
Removing more FP deposits may help decrease the risk for obstructive sleep apnea (OSA), candidiasis (thrush), and speech and swallow dysfunction.
Participants will be on study for up to 3 weeks.

Detaljerad beskrivning
The objective of this study is to test a novel, Extra Virgin Olive-Oil-based Water (EVOOW) mix--designed to leverage ICS physicochemical molecular properties-- for improved removal of orally deposited Fluticasone Propionate (FP) delivered via a Metered Dose Inhaler (MDI) in patients with asthma.
The investigators hypothesize that EVOOW mouthwash will return a greater amount of orally deposited FP than Water rinse. Furthermore, because upper airway ICS deposition from a pressurized MDI is independent of inspiratory flow, the efficacy of EVOOW is not influenced by the presence of asthma.

FP concentration in mouthwashes (ng/mL)
Tidsram: data collected during each of two study visits, 7-10 days apart
|
The primary outcome measure is FP concentration in mouthwashes, measured using mass spectrometry.
The primary comparison of interest is the treatment-by-group interaction, representing the differential treatment effect (EVOOW vs. Water) between asthma and healthy participants.
3 separate 20ml aliquots will be administered and collected during each of 2 study visits, 7-10 days apart.

3 separate 20ml aliquots will be administered and collected during each of 2 study visits, 7-10 days apart. FP drug extraction fraction (EFR) calculated as ([measured FP concentration, ng/ml]/220,000 ng FP delivered)*100 on each of the aliquots. |
