In an open, randomized, triple crossover study, the effects of cisapride and sucralfate on the pharmacokinetics of sparfloxacin were assessed. Fifteen healthy volunteers received 400 mg of sparfloxacin as a single oral dose on day 0. In a random order, concomitant doses of 10 mg of cisapride three times daily from day -2 to day 2 and 1 g of sucralfate four times daily from day -2 to day 0 were ...

Combined treatment with cimetidine 1 g daily and cisapride 40 mg daily in patients with endoscopically diagnosed severe reflux oesophagitis was compared with single drug therapy (cimetidine and placebo). At the end of the six to 12 weeks treatment, 11 (46%) of the 24 patients under single drug therapy were endoscopically healed and three were improved. In contrast, 16 (70%) of the 23 patients u...

AIM To assess the efficacy of cisapride in reducing the time required to establish enteral feeds in preterm infants. METHODS A randomised, double blind, placebo controlled trial was conducted of 34 infants of < or = 32 weeks of gestation, assigned to receive either cisapride 0.2 mg/kg/dose four times daily (n = 18) or placebo (n = 16). RESULTS The time taken by the babies to tolerate full e...

MK-801, a noncompetitive N-methyl-d-aspartate (NMDA) receptor antagonist, enhances gastric emptying while increasing food intake. Although our previously reported results implicate the vagus in MK-801's effect on feeding, it is not clear whether vagal motor fibers participate in the feeding response. Control of gastric emptying is exerted, in part, by cholinergic vagal motor neurons. Therefore,...

BACKGROUND The cardiac sodium channel (SCN5A) mutation L1825P has been identified in a patient with drug-induced torsade de pointes precipitated by the IKr blocker cisapride. Although L1825P generates late sodium current typical of SCN5A-linked long-QT syndrome (LQT3) in vitro, the patient reported had a normal QT interval before administration of the drug. To address this discrepancy, we teste...

Isolated perfused segments of pig ileum and sigmoid colon were used as an extrinsically denervated model of intestinal fluid propulsion to compare the effects of intraluminal (IL) with intraarterial (IA) administration of cisapride and mebeverine. The ileal segments had a spontaneous mean activity of 0.008 (SEM 0.003) ml Krebs propelled aborally min-1, with propulsive waves at a mean frequency ...

AIM To study the effects of elenoside, an arylnaph-thalene lignan from Justicia hyssopifolia, on gastro-intestinal motility in vivo and in vitro in rats. METHODS Routine in vivo experimental assessments were catharsis index, water percentage of boluses, intestinal transit, and codeine antagonism. The groups included were vehicle control (propylene glycol-ethanol-plant oil-tween 80), elenoside...

Twenty children (age range 75 days-47 months) with reflux oesophagitis entered a random double blind trial in which they received either Cisapride (Janssen Pharmaceutical Ltd), a new prokinetic agent, or an identical placebo syrup. Diagnosis of gastro-oesophageal reflux was made by measurement of intraluminal oesophageal pH combined with manometry. Oesophagitis was assessed in all patients by h...
