Review article: An analysis of the pharmacological rationale for selecting drugs to inhibit vomiting or increase gastric emptying during treatment of gastroparesis.
Drugs which can inhibit nausea/vomiting and/or increase gastric emptying are used to treat gastroparesis, mostly 'off-label'. Within each category, they act at different targets and modulate different physiological mechanisms.. Address the questions: In gastroparesis, why should blocking one pathway causing vomiting, be more appropriate than another? Why might increasing gastric emptying via one mechanism be more appropriate than another?. Drugs used clinically were identified via consensus opinions and reviews, excluding the poorly characterised. Their pharmacology was defined, mapped to mechanisms influencing vomiting and gastric emptying, and rationale developed for therapeutic use.. Vomiting: Rationale for 5-HT. Several drug classes inhibiting vomiting have no scientific rationale. NK Topics: Gastric Emptying; Gastroparesis; Humans; Motilin; Nausea; Serotonin; Vomiting | 2023 |
Ghrelin and motilin receptors as drug targets for gastrointestinal disorders.
The gastrointestinal tract is the major source of the related hormones ghrelin and motilin, which act on structurally similar G protein-coupled receptors. Nevertheless, selective receptor agonists are available. The primary roles of endogenous ghrelin and motilin in the digestive system are to increase appetite or hedonic eating (ghrelin) and initiate phase III of gastric migrating myoelectric complexes (motilin). Ghrelin and motilin also both inhibit nausea. In clinical trials, the motilin receptor agonist camicinal increased gastric emptying, but at lower doses reduced gastroparesis symptoms and improved appetite. Ghrelin receptor agonists have been trialled for the treatment of diabetic gastroparesis because of their ability to increase gastric emptying, but with mixed results; however, relamorelin, a ghrelin agonist, reduced nausea and vomiting in patients with this disorder. Treatment of postoperative ileus with a ghrelin receptor agonist proved unsuccessful. Centrally penetrant ghrelin receptor agonists stimulate defecation in animals and humans, although ghrelin itself does not seem to control colorectal function. Thus, the most promising uses of motilin receptor agonists are the treatment of gastroparesis or conditions with slow gastric emptying, and ghrelin receptor agonists hold potential for the reduction of nausea and vomiting, and the treatment of constipation. Therapeutic, gastrointestinal roles for receptor antagonists or inverse agonists have not been identified.

Current treatment of nausea and vomiting associated with gastroparesis: antiemetics, prokinetics, tricyclics.
Gastroparesis is a symptomatic chronic disorder characterized by delayed gastric emptying without a mechanical obstruction. Gastroparesis is most often associated with diabetes, gastric surgery, and systemic disorders affecting the neuromuscular control of the stomach. However, no underlying etiology can be found in up to 40% of patients, a condition referred to as idiopathic gastroparesis. Due to the numerous potential etiologies and the highly variable clinical manifestations, the management of gastroparesis is particularly challenging. The purpose of this review is to provide an update on the use of antiemetics, prokinetics, and tricyclics for the treatment for nausea and vomiting associated with gastroparesis.

[Effects of auricular point sticking on plasma motilin in patients after gynecological laparoscopic operation under general anesthesia].
To observe the clinical efficacy of auricular point sticking on prevention and treatment of gastrointestinal complications after gynecological laparoscopic operation of general anesthesia, and to explore whether it is achieved by regulating the secretion of plasma motilin (MTL).. Sixty patients who received selective gynecological laparoscopy under general anesthesia were randomly assigned into an observation group and a control group, 30 patients in each one. The patients in the observation group were treated with auricular point sticking at each morning and night, 30 min before anesthesia, revival after surgery and 24 h after surgery. The adhesive fabric with vaccaria seeds was pressed at shenmen (TF. Compared with the control group, the occurrence of nausea after operation was reduced in the observation group (. The assist of auricular point sticking could reduce the occurrence of nausea-vomiting and accelerate the recovery of gastrointestinal function in gynecological laparoscopic operation under general anesthesia, which is likely to be related with the inhibition on excess secretion of MTL.

Motilin effects on the proximal stomach in patients with functional dyspepsia and healthy volunteers.
This study investigates motilin effects on the proximal stomach in patients with functional dyspepsia (FD) and healthy volunteers. Eight healthy volunteers and 12 patients with FD were infused with synthetic motilin or placebo. Proximal gastric volume was measured with a barostat at constant pressure and during isobaric distensions. Abdominal symptoms were scored by visual analog scales. Plasma motilin concentrations were measured by radioimmunoassay. Motilin concentrations and baseline gastric volumes were similar for patients and healthy volunteers. Motilin, compared with placebo, reduced gastric volume by 112 ml [F(29,195); confidence interval (CI) 95%] in patients and by 96 ml [F(-7,200); CI 95%] in healthy volunteers. In patients, motilin decreased compliance by 76 ml/mmHg [F(9,143); CI 95%] compared with placebo, which was similar in volunteers [66 ml/mmHg; F(11,120); CI 95%]. Patients were more nauseous during motilin compared with placebo (P = 0.04), whereas healthy volunteers did not experience nausea. We conclude that in a fasted condition, FD patients have a similar proximal gastric motor response to motilin as healthy volunteers, but experience an exaggerated sensation of nausea.

Exogenous motilin affects postprandial proximal gastric motor function and visceral sensation.
Our aim was to investigate the effect of motilin on postprandial proximal gastric motor and sensory function in healthy volunteers. Ten fasted, healthy volunteers were infused intravenously with synthetic motilin or placebo over 90 min. A liquid meal (200 ml) was ingested within 2 min at the start of the infusion. Proximal gastric volume was measured with a barostat device. Abdominal symptoms were scored by visual analog scales. Plasma motilin concentrations were measured using RIA. Endogenous motilin levels were not affected by meal ingestion. After meal intake, gastric relaxation was similar for motilin and placebo. After postprandial relaxation, motilin resulted in a faster return of gastric volume to baseline (P = 0.007). Motilin significantly increased postprandial feelings of nausea (P = 0.03) and tended to increase abdominal pain and abdominal tension. In conclusion, after normal postprandial gastric relaxation, motilin accelerated the return of gastric volume to baseline. In addition, motilin increased postprandial feelings of nausea.

Gastric slow waves, gastrointestinal symptoms and peptides in systemic sclerosis patients.
Impaired gastric slow waves, frequent gastrointestinal (GI) symptoms and altered GI peptides have been reported in Scleroderma (SSc) patients. The aim of this study was to investigate the associations among these three important components in GI dysmotility. Seventeen fasted SSc patients underwent four channel surface electrogastrography, measuring % of normal gastric slow waves or dysrhythmia. Patients completed a questionnaire designed by us to assess demographics, upper and lower GI symptoms (symptom presence, frequency and impact on quality of life, QOL), by YES/NO, Likert Scales and Visual Analogue Scales 1-100 mm (called GI Dysmotility Questionnaire, GIDQ) and health-related QOL by SF-36. Fasting plasma vasoactive intestinal peptide (VIP) and motilin levels were measured by peptide immunoassays. There were significant correlations between percentages of gastric dysrhythmias (bradygastria or arrhythmia) and a number of major GI symptoms such as nausea, abdominal bloating and pain. The plasma level of VIP was correlated positively with % dysrhythmia but negatively with % normal slow waves. Motilin was positively correlated with slow wave coupling (coordination). No major differences were noted in the measured peptides or gastric slow waves between limited SSc and diffuse SSc. Correlations were noted between SF-36 domain scores and our GIDQ scores. In SSc patients, gastric dysrhythmias are correlated with certain GI symptoms. Correlations are also noted between plasma VIP/Motilin levels and gastric slow waves. Thus in SSc, gastric dysrhythmias may be predictive of development of certain dyspeptic symptoms. Plasma VIP may be involved in the development of dysrhythmias.
