bethanechol ↔ tiotropium
Applies to:bethanechol and Spiriva (tiotropium)
GENERALLY AVOID: Anticholinergic agents and other agents with significant anticholinergic activity (e.g., clozapine, class IA antiarrhythmics especially disopyramide) may antagonize the effects of direct-acting cholinergic agents such as bethanechol, carbachol, cevimeline, and pilocarpine. This interaction is sometimes desirable and is the basis for using atropine in the treatment of excessive muscarinic side effects and cholinergic crisis induced by cholinergic overdose. Conversely, cholinergic agents may also counteract the pharmacologic effects of anticholinergic agents and other agents that rely partially on their anticholinergic activity for therapeutic effects (e.g., some antiparkinsonian and antiemetic/antivertigo agents). The mechanism of interaction involves opposing pharmacodynamic action on muscarinic receptor sites.
MANAGEMENT: It may be appropriate to avoid concomitant use of anticholinergic agents and cholinergic agents, depending on the needs of the patient. If concurrent use is necessary, the patient should be monitored for reduced pharmacologic effects of both drugs.

Drug Interaction Classification
The classifications below are a guideline only. The relevance of a particular drug interaction to a specific patient is difficult to determine using this tool alone given the large number of variables that may apply.
| 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. |
