We report one case of parkinsonism induced by cisapride and one case of Parkinson's disease whose symptoms were worsened by cisapride. Case 1. A 75-year-old female who had suffered from constipation and loss of appetite, was treated with cisapride for her gastro-intestinal symptoms. One year later, she developed progressive parkinsonian gait, cogwheel rigidity She showed parkinsonian gait, cogwheel rigidity and slowness in motion. Two months after cisapride was discontinued, her parkinsonism and depression disappeared. Case 2. A 66-year-old female with Parkinson's disease was given cisapride for constipation. Two months after starting cisapride, her akinesia and rigidity deteriorated gradually, and she became bed-ridden with dysphagia and dyspnea. After cisapride was discontinued, her parkinsonian symptoms improved gradually, and she became ambulant three months later. Cisapride is a benzamide derivative with a prokinetic action. Experimental studies have revealed that it has indirect cholinomimetic effects and potentially stimulates the gastrointestinal motor activity without blocking dopamine receptors or activating muscarinic cholinergic receptors. However, the present cases showed that cisapride could be a dopamine receptor blocker, and either induce or worsen parkinsonism. Therefore, cisapride should be avoided or very carefully used in parkinsonian patients and old people.
