Effect of calcitonin on gastric emptying.
The effect on gastric emptying of synthetic salmon calcitonin administered intravenously (415 pmol bolus injection followed by infusion to reach an overall dose of 62.25 pmol.kg-1 body mass) versus placebo was examined in 13 healthy men. Gastric emptying of a radiolabeled solid meal was assessed with a gamma camera. The gastric emptying course was analyzed with the use of the power-exponential fitting. A marked delay in gastric emptying was observed in all subjects studied: the median gastric half emptying time was 60.3 min after placebo and 196.5 min after calcitonin (p less than 0.001). At the same time, analysis of the parameter S revealed that calcitonin did not elicit any consistent change in the shape of gastric emptying curves.
