Tematropium is primarily used in the treatment of chronic obstructive pulmonary disease (COPD) and asthma. It works as a bronchodilator, helping to relax the muscles in the airways and increase airflow to the lungs. This makes breathing easier for patients suffering from these respiratory conditions. It is often administered via inhalation to ensure direct delivery to the lungs, providing quick relief from symptoms like shortness of breath, wheezing, and chest tightness. Additionally, it may be used as part of a long-term management plan to prevent exacerbations and improve overall lung function. Its efficacy and safety profile make it a valuable option in respiratory therapy.
