Spiriva HandiHaler, also known as tiotropium bromide, is a prescription inhalation powder used to treat bronchospasm associated with chronic obstructive pulmonary disease (COPD), which includes chronic bronchitis and emphysema [1]. It is also approved for the treatment of asthma in patients aged six years and older [2]. The HandiHaler device is a dry powder inhaler used to deliver the medication [1].
How Does Spiriva Help with Asthma and COPD?
Spiriva works by blocking the action of acetylcholine on muscarinic receptors in the airways. This leads to bronchodilation, meaning it relaxes and opens the airways, making it easier to breathe [1]. For asthma patients, it is used as a long-acting maintenance bronchodilator, not as a rescue inhaler for sudden breathing problems [2]. In COPD, it helps to reduce exacerbations or flare-ups [1].
