Cisapride for gastric emptying in diabetic patients: a meta-analysis on its efficacy and safety.

Background: Diabetic gastroparesis is a common complication of diabetes, characterized by delayed gastric emptying, significantly impacting patients' quality of life. Current treatment options are limited often resulting in unsatisfactory outcomes. This meta-analysis aims to evaluate the efficacy and safety of cisapride in diabetic patients suffering from gastroparesis.

Methods: A systematic literature search identified 13 studies involving 185 participants. Data on gastric emptying rates, symptom relief, and safety profiles were extracted and analyzed. Effectiveness was measured through gastric emptying half-life (T1/2, measured in min), 120-min gastric emptying rate (measured as a percentage), and adverse events.

Key results: The analysis revealed that cisapride significantly improved gastric emptying compared to placebo, with a mean difference (MD) of -33.74 for T1/2 (95% CI: -68.84 to -2.65, P = 0.03). Additionally, the 120-min gastric emptying rate improved by -25.84 (95% CI: -16.80 to -25.84, P < 0.001). The occurrence of adverse events was low, with most patients tolerating the treatment well.

Conclusion and inferences: Cisapride demonstrates notable efficacy in improving gastric emptying in diabetic gastroparesis, with a generally acceptable safety profile. Clinicians should consider cisapride as a viable treatment option while monitoring patients for any potential side effects. Further research is warranted to explore long-term safety and effectiveness.
