Trial Outcomes & Findings for Aerosol Inhalation Treatment for Dyspnea - Patients (NCT NCT02524054)

NCT ID: NCT02524054

Last Updated: 2018-01-23

Results Overview

Subjects will rate breathing discomfort (dyspnea) during a 15 min exercise test using a visual analog scale before and after drug (or placebo) intervention. The treatment effect was measured as the rating of breathing discomfort rating before treatment minus the rating of breathing discomfort after treatment at equivalent work intensities. Outcome Measure Time Frame: subjects performed arm exercise to induce dyspnea for approximately 15 min before and after aerosol inhalation. the average number of minutes between end of drug administration and post-intervention breathing discomfort rating: Aerosol furosemide Study 2a arm: 38.7 minutes; Aerosol furosemide Study 2b arm: 21.8 minutes; Aerosol saline Study 2b arm: 21.3 minutes

Measure
Aerosol Furosemide Study 2a
Subjects will inhale 40mg of furosemide aerosol over the course of 10-15 min. This will be a single, unblinded administration.
Aerosol Furosemide Study 2b Arm F
Inhalation of furosemide aerosol one one day then placebo saline aerosol on another day. Baseline measurement 15 min; Inhalation over the course of 10-15 min.; outcome measurement 15 min. Watch for adverse effects 2 hours.
Experimental: Aerosol Furosemide Study 2b Arm S
Inhalation of saline aerosol one one day then furosemide aerosol on another day. Baseline measurement 15 min; Inhalation over the course of 10-15 min.; outcome measurement 15 min. Watch for adverse effects 2 hours.

PRIMARY outcome

Timeframe: 15 min

Subjects will rate breathing discomfort (dyspnea) during a 15 min exercise test using a visual analog scale before and after drug (or placebo) intervention. The treatment effect was measured as the rating of breathing discomfort rating before treatment minus the rating of breathing discomfort after treatment at equivalent work intensities. Outcome Measure Time Frame: subjects performed arm exercise to induce dyspnea for approximately 15 min before and after aerosol inhalation. the average number of minutes between end of drug administration and post-intervention breathing discomfort rating: Aerosol furosemide Study 2a arm: 38.7 minutes; Aerosol furosemide Study 2b arm: 21.8 minutes; Aerosol saline Study 2b arm: 21.3 minutes

SECONDARY outcome

Timeframe: Summation of total urine output (mL) at 1 hour following drug administration.

Population: The 17 participants in 'Aerosol furosemide Study 2b' and 'Aerosol saline Study 2b' are the results from the same 17 subjects on two different test days.

Diuresis is an expected effect of furosemide. To the extent that aerosol furosemide is absorbed in the blood, diuresis is an expected 'side effect' of this treatment. Following intervention, study team will measure urine output (mL). Study team will then rehydrate subject with an equal amount of liquid to their output.
