BACKGROUND/AIMS: Polyethylene glycol (PEG) electrolyte lavage solution is now commonly used for peroral colonic preparation. However, the need to ingest a large volume reduces patient acceptance and may limit compliance, thereby resulting in improper preparation. This study was designed to assess whether adding of magnesium oxide or cisapride to PEG solution decreased the volume of PEG solution required without compromising the quality of the preparation. METHODS: One hundred thirty seven patients undergoing outpatient colonoscopy were randomly chosen to receive one of three preparations (Group A: 4 L PEG; Group B: 2 L PEG plus cisapride 20 mg; Group C: 2 L PEG plus magnesium oxide 2 g). Endoscopist was blinded as to the method of preparation and scored the degree of colonic preparation (1 to 4). RESULTS: Mean scores of preparation in group A, B, and C were 2.85, 2.69, and 2.20, respectively (p=0.001). There were significant differences of the degree of preparation between group A and group C, between group B and group C, but not between group A and group B. CONCLUSIONS: Two liters of PEG plus cisapride induced equally effective colonic preparation compared to four liter PEG solution. This results show that the addition of cisapride to PEG solution can reduce volume of PEG solution during colonoscopy preparation.

Pharmacologic treatment of the detrusor hypocontractility(hyporeflexia) remains controversial issues. Clean intermittent self catheterization(CIC) alone, or combination with bethanechol chloride has been generally accepted as treatment modality. Until presently, bethanechol chloride is the only pharmacologic agent commonly used for bladder emptying without significant complication. However, the effectiveness of bethanechol seem to be episodic. The present study compared the contractile response of various pharmacologic agents including bethanechol chloride, ATP, PG E1, E2, F2-alpha on the smooth muscle strips of male rabbit bladder. In addition, effect of the gastrointestinal motility agents such as cisapride and metoclopramide on the contraction of rabbit bladder were assessed. Each bladder was divided into bladder body and bladder base for comparison of pharmacologic effects. FS at basal tension elicited a frequency dependent contraction which was greater in bladder body strips than in bladder base strips. The contractile responses to bethanechol, ATP, PG E1, E2 and PG F2-alpha were greater in bladder body than in bladder base.In the bladder body,magnitude of the contractile responses by ATP and PG F2-alpha were approximately 1/3 of those by bethanechol or FS.PG F2-alpha was consistently more potent to produce contraction than PG E1, E2. ATP induced contraction only consisted of initial phasic rise of tension. The contraction induced by PG developed slower than those caused by bethanechol. Cisapride(10uM) induced weak contractile responses comparable to those by PG E1 Metoclopramide had no contractile effects in this studies. Conclusively, differences exist in the response of the bladder body and base to FS and various pharmacologic agents. ATP, PG E2 and PG F2-alpha exhibited some notable contractile responses to the bladder body that were approximately 1/3 of those by bethanechol. Gastrointestinal motility agents were not shown to be effective in the mediation of contraction of rabbit bladder.

PURPOSE: Cisapride, a prokinetic agent, is widely used in preterm infants with feeding intolerance or gastroesophageal reflux. Although cisapride is regarded as a safe drug, increased QTc interval or ventricular arrhythmia has been reported in adults and neonates. So we prospectively examined the effects of cisapride on the QTc interval and QT dispersion in preterm infants. METHODS: QTc interval and QT dispersion were determined just before and 4.9+/-1.7days after the start of the cisapride treatment in 15 preterm infants with cisapride between April 1, 1998 and August 31, 1998. RESULTS: Cisapride significantly increased QTc interval(P<0.05), and this had no correlation with birthweight or gestational age. Three(20%) of the 15 cases were found to have QTc interval above 0.450, but they were clinically asymptomatic. QT dispersion did not increase significantly. CONCLUSION: Cisapride use in preterm infants is associated with an increase in QTc interval. High dose or longterm use of cisapride in preterm infants should be used cautiously, and when used, monitoring the QTc interval should be considered.

A 41-year-old male patient presented with idiopathic persistent hiccups. The hiccups did not respond to pharmacologic treatments including cisapride, omeprazole, and baclofen. Phrenic nerve block was also ineffective. However, the persistent hiccups were successfully treated with short-term positive pressure ventilation using a short-acting muscle relaxant.

BACKGROUND/AIMS: We evaluated the effects of cisapride tartrate on gastrointestinal symptoms and gastric emptying times in diabetic patients with dysmotility like dyspeptic symptoms. METHODS: Cisapride was administered before each meal in 61 patients for 4 weeks. The intensity of gastrointestinal symptoms before and after cisapride administration was scored from 0 to 4, in the order of increasing severity of symptoms. In addition, a gastric emptying test was performed. RESULTS: A significant reduction in the total intensity score of symptoms was observed during the first two weeks, from 8.5+/-2.1 to 4.0+/-3.0 (p < 0.05), and a further reduction was noted during the next two weeks, to 2.8+/-2.8 (p < 0.05). Good to excellent improvement was obtained in 70.4% of the patients, but the improvement in symptoms was not related to age, duration of diabetes, glucose, Hb A1c, neuropathy, or retinopathy. Treatment with cisapride induced a significant regression of symptoms and a significant improvement of delayed gastric emptying from 104.0+/-31.7 minutes to 79.5+/-17.1 (p < 0.05). However, there was a lack of association between the changes in gastric emptying times and improvements in symptoms(r(2)=0.00186). Only 3 patients complained of loose stool, nausea, or dizziness. CONCLUSIONS: Cisapride was effective in improving dysmotility like dyspeptic symptoms in diabetic patients without serious side effects.

BACKGROUNDS/AIMS: This study was performed prospectively to evaluate the short - term effect of cisapride tartrate on the frequency and the degree of symptoms in patients with functional dyspepsia and functional constipation. METHODS: One-hundred thirty-two patients with a mean age of 44.7 years in men and 43.1 years in women, who presented with symptoms of both functional dyspepsia and functional constipation were recruited, and the frequency and the degree of symptoms corresponding to functional dyspepsia and functional constipation were assessed by an interview in 10 hospitals respectively. In an open, multicenter trial, 132 patients received 10 mg of cisapride tartrate three times a day (TID) for 8 weeks. Patients wrote a defecation diary for 8 weeks and checked symptom scores, which represented the degree of symptoms of dyspepsia and constipation, at the 4th and 8th week. RESULTS: The frequently reported symptoms of functional dyspepsia were epigastric fullness (2.34+/-0.80), bloating (2.05+/-0.82), early satiety (1.67+/-0.99), anorexia (1.04+/-0.95) and nausea (0.94+/-0.93). The mean defecation frequency per week was 3.07+/-2.35 and patients showed subjective symptom scores as follows; 97.0+/-25.26 % in the rate of sense of incomplete evacuation, 1.85+/-0.73 in the hardness of stool and 1.62+/-0.57 in difficulty to pass stool. After adminstration of cisapride tartrate in the case of functional dyspepsia, 66.1% of patients at the 4th week and 81.5 % of patients at the 8th week showed good or excellent improvements. In the case of functional constipation, 82.7% of patients also showed good or excellent improvements. Overall improvements of symptoms in both functional dyspepsia and functional constipation were 78.2% at the 8th week. CONCLUSION: Cisapride tartrate reduced the frequency and the degree of symptoms in functional dyspepsia and functional constipation without significant adverse effects. Functional dyspepsia and functional constipation without significant adverse effects.

BACKGROUND: It has been generally accepted that Cisapride (Prepulsid?or propulsid?), a widely used gastrointestinal prokinetic agent, is associated with Torsades de Points, a life-threatening arrhythmia. Recently, cisapride-induced APD (action potential duration)-prolongation was inhibited by glibenclamide, a KATP channel blocker. But the direct effect of cisapride on K(ATP) channels has not been studied until now. Therefore, we investigated cisapride's effects on KATP channels of isolated rat ventricular myocytes. METHODS: After the isolation of rat ventricular myocytes, we analysed the single channel current with patch pipettes. The method of analysis was the student t-test. RESULTS: 1) Cisapride (10(-6) M- 10(-4) M) inhibited KATP channel opening without changing channel conductance Ki was about 20micronM, and Hill coefficient was 0.75. 2) Cisapride inhibited pinacidil-induced KATP channel opening in the cell attached mode. CONCLUSIONS: These results suggest that cisapride-induced APD prolongation and arrythmic effects may be partly related to KATP channel inhibition.

BACKGROUNDS/AIMS: The therapeutic requirements of patients with non-erosive reflux disease (NERD) are similar to those with erosive esophagitis. The pharmacological action mechanism of prokinetics is quite different; domperidone is a peripheral dopamine D2-antagonist and cisapride is a HT4-agonist. This study was performed to evaluate the therapeutic effect of these two different prokinetics in patients with NERD. METHODS: 178 patients, with heartburn and/or regurgitation, without reflux esophagitis were enrolled and divided into 2 groups by randomization code. In this prospective multicenter trial, 178 patients (93 patients in cisapride group, 85 patients in domperidone group) received 10 mg of cisapride three times a day or 10 mg of domperidone three time a day for 2 or 4 weeks. Symptom assessment was performed in each patients before treatments, 2 and 4 weeks after treatment. RESULTS: Of the 133 patients available for final analysis, 65 were allocated to the cisapride group and 68 to the domperidone group. After 2 weeks treatment, heartburn was reduced in 81.1% of cisapride group, 56.7% of domperidone group (p < 0.05) and regurgitation was reduced in 89.7% of cisapride group, 77.7% of domperidone group. After 4 weeks treatment, heartburn was reduced in 94.3% of cisapride group, 88.7% of domperidone group and this difference was not significant. The proportion of adverse events in cisapride group was 9.4% and was 5.5% in domperidone group. CONCLUSIONS: Cisapride tartrate was more effective in relieving heartburn in NERD patients than domperidone maleate after 2 week treatment. However, this superior effect dose not persist longer than 2 weeks.
