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.
Nasal ipratropium (Atrovent Nasal) works to dry up nasal secretions and is recommended for the treatment of allergic rhinitis, non-allergic rhinitis, and symptoms of the common cold. It works great at treating a âdrippy nose,â but will not treat nasal itching or nasal congestion symptoms.
