COPD Home > Tudorza

People who have airway spasms caused by chronic obstructive pulmonary disease may receive Tudorza. This prescription medication is inhaled into the lungs twice daily. Headaches, coughing, and common cold symptoms are possible side effects. As an anticholinergic, this product works by relaxing the muscles of the airways, helping to keep them open.

What Is Tudorza?

Tudorza™ Pressair™ (aclidinium bromide) is a prescription medication used for the long-term treatment of airway spasms (called bronchospasms) caused by chronic obstructive pulmonary disease (COPD), including chronic bronchitis and emphysema.

How Does Tudorza Work?

Tudorza belongs to a group of medications known as anticholinergics. By binding to specific receptors (called muscarinic receptors) in the airway, Tudorza helps to relax the smooth muscle of the airway. As a long-acting medication, it helps to prevent bronchospasms, helping to keep the airways open, with just two doses each day.

Clinical Effects

Tudorza was studied in the treatment of COPD. People using this medication showed improved lung function, compared to those not using it. In addition, these studies showed that the effects of each dose lasted for at least 12 hours, and people who used the medication were less likely to need doses of "rescue" inhalers, such as albuterol.
