Drug Interaction Report

MONITOR: Concomitant administration of anticholinergic agents would be expected to reduce the therapeutic effects of prucalopride. Prucalopride increases bowel motility by stimulating colonic peristalsis (high-amplitude propagating contractions), an action that has been shown to be facilitated by acetylcholine release in isolated gastrointestinal tissues from various animal species.

MANAGEMENT: Monitoring for altered efficacy of prucalopride may be advisable during concomitant use with anticholinergic agents.

GENERALLY AVOID: Use of anticholinergic agents with alcohol may result in sufficient impairment of attention so as to render driving and operating machinery more hazardous. In addition, the potential for abuse may be increased with the combination. The mechanism of interaction is not established but may involve additive depressant effects on the central nervous system. No effect of oral propantheline or atropine on blood alcohol levels was observed in healthy volunteers when administered before ingestion of a standard ethanol load. However, one study found impairment of attention in subjects given atropine 0.5 mg or glycopyrrolate 1 mg in combination with alcohol.

MANAGEMENT: Alcohol should generally be avoided during therapy with anticholinergic agents. Patients should be counseled to avoid activities requiring mental alertness until they know how these agents affect them.
