Combivent respimat, which is a propellant-free inhaler product uses a slow-moving mist to deliver the same active ingredients of Combivent Inhalation Aerosol in a metered dose inhaler (Combivent MDI).
Combivent MDI and Combivent respimat are short-acting bronchodilator products that offer two different medicines in a single inhaler.
The efficacy of the spray was studied in a 12-week, randomized, double-blind, placebo and active-controlled clinical trial.
The data demonstrated that Combivent respimat was clinically comparable to Combivent MDI, in terms of FEV1, which is the maximal amount of air that can be forcefully exhaled in one second.
