Spiriva (tiotropium) Disease Interactions

There are 5 disease interactions with Spiriva (tiotropium):


Inhaled Anticholinergic Agents (Includes Spiriva) ↔ Angioedema

Moderate Potential Hazard, Moderate plausibility

Applies to: Angioedema

Angioedema has been reported during therapy with inhaled anticholinergic agents. Therapy with these agents should be administered cautiously in patients at risk of developing angioedema and if such reaction occurs during treatment, therapy should be stopped at once and alternative treatments should be considered. In addition, therapy with Spiriva HandiHaler should be used with caution in patients with severe hypersensitivity to milk proteins as the product contains the inactive ingredient, lactose monohydrate.


Inhaled Anticholinergic Agents (Includes Spiriva) ↔ Anticholinergic Effects

Moderate Potential Hazard, Moderate plausibility

Applies to: Urinary Retention, Glaucoma (Narrow Angle)

Aclidinium, ipratropium, and tiotropium are anticholinergic agents. Although systemic effects are uncommon due to the poor absorption of quaternary ammonium compounds from gastrointestinal and nasal mucosa, worsening of urinary retention or angle-closure glaucoma has been reported. Increased intraocular pressure and precipitation or exacerbation of angle-closure glaucoma may also occur due to inadvertent contact of the eye with aerosolized or nebulized drug. Accordingly, therapy with quaternary ammonium compounds should be administered cautiously in patients with urinary retention/obstruction or angle-closure glaucoma. Measures should be taken whenever possible to minimize ocular exposure to these drugs, such as keeping eyes closed during oral inhalation or use of a mouthpiece rather than face mask during nebulization. Patients should be advised to contact their physician if they experience urinary difficulty or signs and symptoms of angle-closure glaucoma (e.g., eye pain or discomfort; blurred vision; visual halos; colored images in association with red eyes from conjunctival congestion or corneal edema).

Inhaled Anticholinergic Agents (Includes Spiriva) ↔ Tachycardia

Moderate Potential Hazard, Moderate plausibility

Applies to: Arrhythmias

Cases of supraventricular tachycardia and atrial fibrillation have been reported with the use of inhaled anticholinergic agents in patients with COPD/Asthma. Care and monitoring of cardiac function is recommended when prescribing these agents to patients at risk.


Tiotropium (Includes Spiriva) ↔ Liver

Moderate Potential Hazard, Moderate plausibility

Applies to: Liver Disease

The effects of hepatic impairment on the pharmacokinetics of tiotropium have not been studied. Caution is recommended when prescribing this agent to patients with impaired liver function.


Tiotropium (Includes Spiriva) ↔ Renal Dysfunction

Moderate Potential Hazard, Low plausibility

Applies to: Renal Dysfunction

Tiotropium is primarily eliminated unchanged by the kidney. Renal impairment has been associated with increased plasma drug concentrations and reduced drug clearance after both intravenous infusion and dry powder inhalation. Mild renal impairment (CrCl 50 to 80 mL/min), which is often seen in elderly patients, increased tiotropium systemic exposure (AUC) by 39% following intravenous infusion. In COPD patients with moderate to severe renal impairment (CrCl < or equals to 50 mL/min), tiotropium AUC increased 82% following intravenous administration, which was confirmed by plasma concentrations after dry powder inhalation. Although generally well tolerated, therapy with ipratropium should be administered cautiously in patients with moderate to severe renal impairment. Monitoring for renal function is recommended. Patients should be advised of and monitored for potentially increased systemic adverse effects such as constipation, tachycardia, blurred vision, glaucoma, urinary difficulty, and urinary retention.

Drug Interaction Classification

The classifications below are a general guideline only. It is difficult to determine the relevance of a particular drug interaction to any individual given the large number of variables.
Major Highly clinically significant. Avoid combinations; the risk of the interaction outweighs the benefit.
Moderate Moderately clinically significant. Usually avoid combinations; use it only under special circumstances.
Minor Minimally clinically significant. Minimize risk; assess risk and consider an alternative drug, take steps to circumvent the interaction risk and/or institute a monitoring plan.
Unknown No information available.
