Abstract

TRONCON, Luiz Ernesto de Almeida. New drugs for the treatment of functional dyspepsia. Arq. Gastroenterol. [online]. 2001, vol.38, n.3, pp.207-212. ISSN 1678-4219.  http://dx.doi.org/10.1590/S0004-28032001000300012.

Background — Functional dyspepsia is defined by upper gastrointestinal symptoms without any evidence of structural abnormalities or organic disease. Current pharmacological treatment of functional dyspepsia is largely empirical and involves anti-secretory or prokinetic drugs. Aims - To review recent advances in the understanding of the mechanisms involved in symptom production in functional dyspepsia, as well as the development of new drugs that may interfere with these mechanisms, which may lead to more rational and effective treatment of this clinical condition. Method - Systematic review of papers published in English for the last 10 years. Results - New drugs that increase propulsive gastroduodenal motor activity include new benzamides similar to cisapride, CCK-A blockers, agonists of opiate receptors and motilin agonists similar to erythromycin. A number of agents, including sumatriptan and buspirone, stimulates serotonin receptors in the myoenteric plexuses and have been shown to increase gastric accommodation to a meal. Finally, a number of new drugs that either increase thresholds for visceral perception or modify sensations is currently under investigation. This includes agents of several groups, such as octreotide, loxiglumide, ondansetron and other serotonin blockers, fedotozine and tricyclic antidepressant at low doses. Conclusions - Although these new drugs may improve the pharmacological approach to the treatment of functional dyspepsia, there is a need for randomized, controlled trials to assess their efficacy. Moreover, difficulties related to the identification of the mechanisms underlying symptoms may limit the utilization of these new drugs.
