Tioron are the Rotacaps that contain tiotropium and belong to the group of medications known as bronchodilators. These Rotacaps are used to prevent wheezing, coughing, and chest tightness in patients with chronic obstructive pulmonary disease (COPD, a group of illnesses that affect the lungs and airways), including chronic bronchitis (swelling of the air passages that lead to the lungs), and emphysema. Tioron RotaCaps facilitate breathing by relaxing and widening the airways to the lungs.
