Media richness theory. Media Richness Theory, sometimes referred to as information richness theory or MRT, is a framework used to describe a communication medium's ability to reproduce the information sent over it. It was introduced by Richard L. Daft and Robert H. Lengel in 1986 as an extension of information processing theory.
Albuterol and ipratropium is a combination bronchodilator that relaxes muscles in the airways and increases air flow to the lungs. Albuterol and ipratropium inhalation is used to prevent bronchospasm in people with chronic obstructive pulmonary disease (COPD) who are also using other medicines to control their condition.
The combination of ipratropium and albuterol eases constriction of the airways by relaxing the surrounding smooth muscle. Combivent Respimat replaces the Combivent metered-dose inhaler, which was taken off the market to comply with the Clean Air Act. There is no generic alternative available. However, DuoNeb (generic ipratropium/albuterol) has the same combination of active ingredients for use with a nebulizer.
