Colestyramine slows gastric emptying of liquids and reduces appetite in healthy subjects

Abstract

This study provides the first evidence that colestyramine significantly slows liquid gastric emptying and reduces appetite in healthy humans. Colestyramine therefore presents an attractive gut-brain signaling research tool in that it is not absorbed and thus lacks potentially confounding postabsorptive effects. Furthermore, with clear effects on gastric emptying and appetite, colestyramine now merits consideration as a trial therapeutic strategy for appetite suppression and weight loss.
