Topium Rotacap contains Tiotropium Bromide, a long-acting bronchodilator used to manage and treat chronic obstructive pulmonary disease (COPD) and asthma. It works by relaxing the muscles in the airways, which helps open the air passages and makes it easier to breathe. Topium Rotacap is delivered through a rotahaler device, which allows the medication to be inhaled directly into the lungs for quick and effective relief.
