Obesity Clinical Trial
Official title:
The Effect of Quinine Hydrochloride on Hedonic Food Intake, Appetite-related Sensations and Gastrointestinal Hormone Release in Overweight Female Subjects
The worldwide increase in the prevalence of obesity is a cause of great concern. Pharmacological treatment options are being explored at the moment with a major focus on the hormones produced by the gastrointestinal tract which regulate hunger and satiation/satiety. Modulating the release of these hormones via bitter substances reduced appetite-related sensations and gastrointestinal motility in lean female volunteers. Intragastric administration of a quinine-solution has shown to decrease hunger sensations in healthy female volunteers. Now, we want to examine whether this effect is still seen in an overweight female population.
The aim of this study is to investigate the effect of acute administration of quinine hydrochloride on the consumed milkshake volume, gastrointestinal hormone levels, appetite-related sensations and whole blood glucose levels in overweight female individuals. This study is a randomized, placebo-controlled, double blinded, cross-over study. Forty healthy overweight females will be recruited. An acute dose of 320 mg of quinine hydrochloride is administered as a solution via a nasogastric feeding tube. Blood samples will be collected at regular time points to measure gastrointestinal hormone release and whole blood glucose levels. Appetite related sensations will be scored at regular time points on visual analogue scales. ;
