About

Asthma is a long-term inflammatory disease of the airways that causes recurring wheezing, coughing, chest tightness, and shortness of breath, and can flare into attacks when allergens or dust are inhaled and the airways narrow and fill with mucus. Trimbow is an inhaler that delivers three medicines at once: a steroid that calms airway inflammation, plus two bronchodilators that relax tightened airway muscles and keep the breathing passages open. Together these actions may help people with asthma breathe more easily and reduce how often symptoms flare.
