Effects of the 5-HT3 receptor antagonist ICS 205-930 on fat-delayed gastric emptying and antral motor activity.

1. The selective 5-HT3 receptor antagonist, ICS 205-930 (Sandoz), has been reported to have potent effects on gastric smooth muscle in vivo and to enhance gastric emptying in animals and in man. 2.

Oesophageal and gastric motor activity in patients with bulimia nervosa.

Previous studies showed that symptoms of oesophageal motor disorders can be misinterpreted as indicating anorexia nervosa and that in primary anorexia nervosa gastric motility is frequently impaired. We investigated in 32 women with bulimia nervosa whether symptoms of oesophageal motor disorders could be obscured by or be mistaken as forming part of bulimic behaviour, and whether impaired gastric motility was frequent as well. Oesophageal motility was normal in 18 of 26 patients studied, another four had incomplete lower oesophageal sphincter relaxation.

Effects of a 5-hydroxytryptamine3 receptor antagonist (ICS 205-930) on colonic motor activity in healthy men.

1. ICS 205-930 (Sandoz) is a selective antagonist at 5-hydroxytryptamine3 receptors and exerts marked effects on gastrointestinal motility in animals. 2.

Effects of cisapride on postcibal jejunal motor activity.

In the jejunum of fasting humans, cisapride induces a phase 2-like, highly propagative motor pattern. This study investigated cisapride's effects on the fed pattern of the jejunum. Starting 5 min after a phase 3 of the migrating motor complex, 18 healthy men received 5 or 10 mg cisapride or placebo orally in random double-blind fashion and ingested meals containing 1000 and 4200 kJ, respectively.
