Conclusions The intention of the authors was to acquaint the readers with a complete overview of the effects of drugs and stimulants on the GMA. This is a significant issue, particularly for physicians performing and interpreting EGG tests. It is also of importance to practitioners carrying out pharmacotherapy aimed at normalisation of GMA associated with functional gastrointestinal disorders, and a number of organic diseases within and beyond the digestive system. The examinations mentioned in this article were performed using a single-channel electrogastrographic recording system. We hope that the knowledge of the pharmacological modulation of GMA will soon be enriched by studies performed using newly available multichannel EGG, whose significant advantage over traditional methods is the registration of slow wave propagation in the stomach [38], possibly resulting in significantly deepening our understanding of the pharmacological impact on the GMA and... thus requiring further updating of this article.
