Concomitant treatment with other drugs possessing antimuscarinic properties may result in more pronounced therapeutic effect and side effects. Conversely, therapeutic effect of tolterodine may be reduced by concomitant administration of muscarinic cholinergic receptor agonist. Effect of prokinetics like metoclopramide and cisapride may be decreased by tolterodine.
