Introduction
Tiotropium bromide, as a long-acting anticholinergic bronchodilator, is primarily used for the maintenance treatment of chronic obstructive pulmonary disease (COPD). Rinsing the mouth after inhaling tiotropium bromide is mainly intended to reduce local oral irritation, prevent fungal infections, lower the risk of pharyngeal discomfort, avoid the effects of drug residue, and protect the health of the oral mucosa.

As a long-acting anticholinergic bronchodilator, tiotropium bromide is primarily used for the maintenance treatment of chronic obstructive pulmonary disease (COPD). Rinsing the mouth after inhaling tiotropium is recommended to reduce local oral irritation, prevent fungal infections, lower the risk of throat discomfort, avoid adverse effects from drug residue, and protect the health of oral mucosa. If persistent oral pain, rash, or breathing difficulties occur even after rinsing, medical attention should be sought promptly.

1. Reduce Local Oral Irritation: Tiotropium belongs to the class of anticholinergic drugs. When left in the mouth, it may irritate the mucous membranes, causing dry mouth, bitter taste, or a burning sensation. Rinsing helps quickly remove residual medication and alleviate local discomfort.

2. Prevent Fungal Infections: Drug residue can disrupt the natural balance of oral flora, increasing the risk of Candida infection—especially in individuals on long-term therapy. Rinsing reduces the favorable environment for fungal growth and lowers the likelihood of infection.

3. Lower Risk of Throat Discomfort: Residual medication may irritate the throat lining, leading to itching, a sensation of a foreign body, or worsened cough. Rinsing helps prevent prolonged exposure and reduces these symptoms.

4. Avoid Impact of Drug Residue: Medication remaining in the mouth does not contribute to therapeutic effects and may enter the gastrointestinal tract upon swallowing, imposing unnecessary systemic burden. Rinsing thoroughly removes residues and ensures precise and effective drug delivery.

5. Protect Oral Mucosal Health: Repeated exposure to the drug during long-term use may damage the protective barrier of the oral mucosa. Regular rinsing minimizes cumulative irritation and helps maintain normal mucosal function.

After inhaling tiotropium bromide, rinse thoroughly with lukewarm water, ensuring both sides of the mouth and the throat area are cleaned. Rinse for at least 30 seconds, then spit out the water—do not swallow. Clean the inhalation device promptly after use and keep it dry and hygienic to ensure safe and effective medication administration.
