Tiotropium is a long-acting anticholinergic bronchodilator used to facilitate easier breathing in chronic obstructive pulmonary disease patients.
Tiotropium belongs to a group of medicines called long-acting anticholinergics. It is designed to keep the airways in the lungs open, making breathing easier for people with certain lung conditions. In Hong Kong, tiotropium is most often found in inhalation products marketed as tiotropium bromide.
In Hong Kong the principal products that deliver tiotropium are inhalers. The most widely available brand is Spiriva Respimat, a soft-mist inhaler that releases a measured dose of tiotropium bromide. The same active ingredient is also sold as a generic inhalation aerosol, often labelled simply as tiotropium bromide inhaler. Both the brand-name and generic versions come in single-use or reusable devices, and the inhaled dose is measured in micrograms (µg) per puff.
Tiotropium is approved for use in the following situations:
These conditions share a common problem: the muscles around the airways tighten, narrowing the passage for air. By relaxing those muscles, tiotropium makes it easier for air to move in and out of the lungs.
When you inhale a dose, tiotropium reaches the smooth muscle lining the airways and blocks a chemical messenger that normally tells these muscles to tighten. This blockage lasts for about 24 hours, so the airways stay more relaxed throughout the day. Because it works locally in the lungs, the effect is felt relatively quickly after the first inhalation, and the benefit continues with daily use.
These reactions are usually temporary and tend to improve as the body gets used to the medicine.
If any of these signs appear, seek urgent medical help.

Store inhalers at room temperature away from direct sunlight and moisture. Do not freeze them. Most tiotropium products are meant for daily use, but the exact length of treatment depends on the individual’s health plan. Always follow the instructions that come with the specific inhaler you are using, as device handling can differ between the Respimat soft-mist system and other aerosol devices.
For detailed usage, dosing, and administration, refer to the labeling of your particular tiotropium product.
Anticholinergic: A type of medicine that blocks a signal causing airway muscles to tighten.
Inhalation aerosol: A spray device that delivers medication directly to the lungs when you breathe in.
Soft-mist inhaler: A device that creates a fine, slow-moving cloud of medication, making it easier to inhale.
