Tudorza Pressair (generic: aclidinium) is a prescription medication used to prevent wheezing, shortness of breath, coughing, and chest tightness caused by chronic obstructive pulmonary disease (COPD). Tudorza belongs to a group of drugs called bronchodilators which work by relaxing the smooth muscle of the airways, opening the air passages to the lungs which makes it easier to breathe.

This medication comes in the form of a dry powder in an inhaler, to be inhaled into the lungs, usually twice daily.

Common side effects of Tudorza Pressair include headaches, runny or stuffy nose, and cough.
