ONBREZ BREEZHALER, also known by its generic name indacaterol, is a long-acting bronchodilator used in the management of chronic obstructive pulmonary disease (COPD), including chronic bronchitis and emphysema. It is specifically designed to help open the airways and make breathing easier for adults who suffer from breathing difficulties associated with COPD. ONBREZ BREEZHALER works by relaxing the muscles in the walls of the small air passages in the lungs, helping to keep the airways open for at least 24 hours. This medication is taken through inhalation using a special inhaler device called the Breezhaler, which is specifically designed for this purpose. It is important to note that ONBREZ BREEZHALER is not intended for the relief of acute bronchospasm or for the treatment of asthma.
