Chronic obstructive pulmonary disease (COPD) is a lung disease that includes the conditions chronic bronchitis and emphysema. COPD is mainly caused by smoking or inhaling dust, which leads to blockage or narrowing of the airways. The symptoms include breathlessness and a chronic cough. Tiotropium is an inhaled medication, taken once a day, to help widen the airways (bronchodilator) and is used in the management of COPD. Ipratropium bromide is also a bronchodilator but has a shorter duration of action and has to be taken several times a day.
