Oesophageal emptying of solids was studied with a scintigraphic technique in 12 patients with insulin dependent diabetes complicated by autonomic neuropathy and in 22 control subjects. In the diabetics the acute and chronic effects of oral domperidone on oesophageal emptying and symptoms of heartburn and dysphagia were assessed. The number of swallows required to clear the oesophagus in the diabetics (median 9.5, range 2-30) was significantly greater (P less than 0.001) than in normal controls (median 2, range 1-14). Domperidone did not increase solid oesophageal emptying in diabetic patients either after acute or after chronic administration.

Gastrointestinal (GI) motility disorders are frequent in patients with Parkinson's disease, manifesting mainly as dysphagia, disorders of gastric emptying and constipation. The most likely causes of these disorders are cerebral degeneration and degeneration of the myenteric plexus. Although the effect of antiparkinsonian medication is largely overestimated, it certainly has an influence and should be adapted accordingly in patients with GI motility disorders. In particular, anticholinergic drugs should be avoided, and anamnesis, clinical examination and, if necessary, diagnostic tests performed. Domperidone, a peripheral dopamine antagonist, is the drug of choice for motility disorders of the upper GI tract, although cisapride is an alternative. In the lower GI tract, conservative therapeutic options should be used in the first instance. The administration of cisapride leads to a marked temporary improvement in symptoms in lower GI disorders, while rare forms of anism (involuntary dystonic contraction of the anal sphincter) may be treated with botulinum toxin.

This study investigated whether domperidone could improve gastrointestinal symptoms in patients with Parkinson's disease who were receiving levodopa therapy. A total of 11 patients were studied. Following a baseline gastric emptying test, patients were treated with a starting dose of domperidone 20 mg p.o. q.i.d. A follow-up gastric emptying test was repeated at least 4 months after starting domperidone therapy. At the beginning and at each 3-month follow-up visit, symptoms of nausea, vomiting, anorexia, abdominal bloating, heartburn, regurgitation, dysphagia, and constipation were evaluated and scored on a scale of 0-3. The overall mean follow-up period was 3 years. Compared with their baseline evaluation, patients experienced a significant improvement in all symptoms (p < 0.05) except dysphagia and constipation. Gastric emptying of an isotope-labeled solid meal was significantly faster, with a baseline result of 60.2 +/- 6.4% retention of isotope 2 h after the meal compared with 37.0 +/- 2.2% retention during domperidone therapy (p < 0.05). Patients' global assessment of Parkinson's disease remained stable or improved. Serum prolactin was elevated in all patients after domperidone therapy (p < 0.05). Domperidone therapy significantly reduces upper gastrointestinal symptoms and accelerates gastric emptying of a solid meal, but does not interfere with response to antiparkinsonism treatment.
