Primaire uitkomstmaten
Esophageal sensitivy to acid perfusion (perfusion-related symptom score).
Achtergrond van het onderzoek
Many of the patients presenting with typical reflux symptoms who do not respond to the current standard of care (i.e. proton pump inhibition), do not have gastro-esophageal reflux disease. Functional heartburn is an important differential diagnosis in this respect, and can be confirmed or excluded by performing a 24h pH/impedance recording: patients with functional heartburn do not have pathological acid reflux and the symptom-reflux association analysis is typically negative.
The management of functional heartburn is often challenging as evidence-based pharmacological options are not available. The use of visceral pain modulators such as tricyclic antidepressants is generally accepted, even though the clinical trials to support their use are likewise lacking.
The aim of the current trial is to validate the use of amitriptylin in functional heartburn and to study its mechanism of action.
Doel van het onderzoek
Amitriptyline ameliorates heartburn complaints in functional heartburn patients by modulating visceral perception.
Onderzoeksopzet
6 and 20 weeks after start of compound.
Onderzoeksproduct en/of interventie
Amitriptylin 25-50 mg daily or placebo for 6 weeks in a crossover design.

Belangrijkste voorwaarden om deel te mogen nemen (Inclusiecriteria)
1. Minimum age: 18 years;
2. Documented functional heartburn:
A. Negative esophagogastroduodenoscopy and no history of reflux esophagitis;
B. Negative 24h pH/impedance recording (physiological acid exposure time) and negative symptom association probability.
Belangrijkste redenen om niet deel te kunnen nemen (Exclusiecriteria)
1. Surgery of the esophagus;
2. Motility disorders of the GI tract leading to delayed gastric emptying or altered intestinal motility;
3. Use of any medication with a potential effect on upper gastrointestinal motility and/or sensitivity that can not be stopped for the duration of the study. If this medication can be stopped, it should be discontinued for at least 2 weeks before the start of the study;
4. Severe and clinically unstable concomitant disease (e.g. liver, cardiovascular or lung disease, neurological or psychiatric disorders, cancer or AIDS and other endocrine disorders);
5. Pregnancy or lactation. A pregnancy test will be carried out prior to inclusion in the study. Female patients who are premenopausal and have a negative pregnancy test should be on an anticonceptive;
6. Medication-related:
A. Contra-indications for amitriptyline use: epilepsy, organic central nervous system disorders, prostate hypertrophy, pyloric stenosis, cardiovascular disease, hyperthyroidism, liver- and kidney function impairment;
B. Interaction can occur with barbiturates, carbamazepine, ketoconazol and ritonavir . Concommitant use of MAO-inhibitors is contra-indicated.
7. Hypersensitivity to the active substance or to any of the excipients.
