Moderate evidence was found to support the use of PPIs, along with some evidence to support the use of H₂ antagonists in older children with GORD, based on improvement in symptom scores, pH indices and endoscopic/histological appearances. However, lack of independent placebo-controlled and head-to-head trials makes conclusions as to relative efficacy difficult to determine. Further RCTs are recommended. No robust RCT evidence is available to support the use of domperidone, and further studies on prokinetics are recommended, including assessments of erythromycin.Pharmacological treatment of infants with reflux symptoms is problematic, as many infants have GOR, and little correlation has been noted between reported symptoms and endoscopic and pH findings. Better evidence has been found to support the use of PPIs in infants with GORD, but heterogeneity in outcomes and in study design impairs interpretation of placebo-controlled data regarding efficacy. Some evidence is available to support the use of Gaviscon Infant(®) , but further studies with longer follow-up times are recommended. Studies of omeprazole and lansoprazole in infants with functional GOR have demonstrated variable benefit, probably because of differences in inclusion criteria.No robust RCT evidence has been found regarding treatment of preterm babies with GOR/GORD or children with neurodisabilities. Initiation of RCTs with common endpoints is recommended, given the frequency of treatment and the use of multiple antireflux agents in these children.

The incidence of pneumonia during the observation period was significantly lower in the mosapride group as compared to the control (7/38 vs. 16/40, p = 0.038) and lansoprazole (vs. 20/41, p = 0.005) groups. The mosapride group also showed a significant decrease in days with fever and antibiotics administration as compared to the other groups. Multivariate analysis revealed that the presence of hiatal hernia was a significant risk factor and administration of mosapride was a significant preventive factor for pneumonia.

Twenty-six patients in the PPI group and 26 patients in the H2RA group, excluding dropouts, were analyzed. There were no significant differences in median age, sex, underlying disease, smoking status, H. pylori infection, prevalence of ulcers before treatment, and lesion site between the two groups. The therapeutic effects were endoscopically evaluated as healed in 23 patients (88.5%) and not healed in 3 patients in the PPI group and as healed in 22 patients (84.6%) and not healed in 4 patients in the H2RA group. Abdominal symptoms before treatment were uncommon in both groups; the GSRS scores were not significantly reduced after treatment as compared with before treatment.

An LC-MS/MS method was developed and validated to be used as a stability indicating assay for the study of a 3 mg/mL lansoprazole oral suspension. The method utilizes a UPLC (ultra-performance liquid chromatography) column and unique mass spectrometric detection (ion-trap time-of-flight (IT-TOF)) to achieve a sensitive (LOD 2 ng/mL), accurate, and reproducible quantification of lansoprazole. This method reports an intraday and interday coefficient of variation of 2.98 ± 2.17% (n = 5 for each concentration for each day) and 3.07 ± 0.89% (n = 20 for each concentration), respectively. Calibration curves (5-25 μg/mL) were found to be linear with an R(2) value ranging from 0.9972 to 0.9991 on 4 different days. Accuracy of the assay, expressed as % error, ranged from 0.30 to 5.22%. This method is useful for monitoring the stability of lansoprazole in oral suspension.

Rhabdomyolysis is an acute skeletal muscle disorder characterized by altered integrity of the cell membranes of muscle fiber cells. It can be related to a variety of factors: muscular trauma, muscle enzyme deficiencies, infections, drugs, toxins, alcohol ingestion, endocrinopathies and electrolyte imbalances such as hypokalemia. We report the case of a 46-year-old woman admitted to the Emergency Department for frequent episodes of vomiting associated with food intake in the last two weeks, general muscular weakness and myalgia. Physical examination on admission was unremarkable, except for a symmetrical and dominantly proximal muscular weakness of all four extremities. Blood pressure was 116/70 mmHg with a sinus bradycardia (53 beats/min) on the electrocardiogram. Laboratory tests showed a metabolic alkalosis with marked hypokalemia (K+= 1.9 mEq/l) and elevation of muscular enzymes (myglobin= 993 ng/ml, troponin T= 0,10 ng/ml e CK= 1113 U/l). No symptoms of recurrent rhabdomyolysis were reported, patient denied alcohol consumption and there was not clinical evidence of hyperthyroidism. A iatrogenic etiology could not be excluded for certain because patient was in therapy with lansoprazole (Naranjo algorithm 3/13) but, revealing medical history that she underwent a laparoscopic adjustable gastric banding for the treatment of a severe obesity, we focused our attention on hypokalemia, due to persistent vomiting. Fasting, administration of metoclopramide and infusion of potassium chloride resulted in steady improvement of clinical conditions and normalization of electrolyte imbalance. At the clinical follow-up of three months, after partial deflation of the gastric banding, the patient was asymptomatic with muscular enzymes and potassium levels in the normal range. Authors discuss the pathophysiologic mechanisms of these alterations.

Bismuth quadruple therapy is preferable to 14-day triple therapy in the first-line treatment in the face of rising prevalence of clarithromycin resistance. Concomitant therapy given for 10 days might not be optimum and a longer treatment length should be considered.
This study included 48 patients with peptic ulcer disease. Helicobacter pylori infection was confirmed by a rapid urease test and histological examination of samples obtained from the antrum and corpus during endoscopy. The eradication therapy consisted of a 7-day twice daily oral administration of lansoprazole 30 mg, furazolidone 200 mg and levofloxacin 250 mg. Therapeutic success was confirmed by a negative rapid urease test, histological examination and 14C- urea breath test, performed 12 weeks after treatment completion. The Chi-square method was used for comparisons among eradication rates, previous treatments and previous furazolidone use.

Sixty-three H. pylori-positive patients and thirty H. pylori-negative patients were studied. Serum copper, zinc, and selenium levels had no significant difference between H. pylori-positive and H. pylori-negative groups. There were 49 patients with successful H. pylori eradication. The serum selenium levels were lower after successful H. pylori eradication, but not significantly (P = 0.06). There were 14 patients with failed H. pylori eradication. In this failed group, the serum selenium level after H. pylori eradication therapy was significantly lower than that before H. pylori eradication therapy (P < 0.05). The serum zinc and copper levels had no significant difference between before and after H. pylori eradication therapies.

Adverse drug event (ADE) rates resulting from coadministration of proton pump inhibitors (PPIs) and other drugs with potential for interaction with PPIs (DPIs) are unknown. This retrospective study assesses the occurrence of such ADEs and their potential impact on medical care costs by reviewing integrated medical and pharmacy claims. Managed care patients receiving one or more DPIs were identified. Within this sample, those who were also prescribed omeprazole or lansoprazole (DPI + PPI) were included. A second cohort (DPI alone) was created, matching for age, gender, and DPI use. Rates of ADEs were followed for 6 months after entry. Among PPI users, 58% used one or more DPIs, whereas 7% of DPI subjects used a PPI. Among claims arising from ADEs occurring in more than 1% of patients, 14 occurred in the DPI + PPI group and 2 occurred in the DPI-alone cohort, respectively, a highly significant difference. Crude odds ratios for the risks of specific ADEs were significantly increased for cotherapy with a PPI and warfarin, clarithromycin, corticosteroids, carbamazepine, nifedipine, or diclofenac. After adjustment, the first three associations remained significant. Coprescription of a PPI with potentially interacting drugs was common in practice and associated with significantly increased claims for medical care.

The protective effects of the proton pump inhibitor lansoprazole on gastric mucosal damage induced by ethanol-HCl or hemorrhagic shock were investigated in the present study. The morphometric analysis of gastric histological sections revealed that lansoprazole dose-dependently reduced mucosal injury evoked by ethanol-HCl (ED50 = 24.3 micromol/kg) or hemorrhagic shock (ED50 = 38.9 micromol/kg), these effects being associated with marked increments of Alcian blue recovery from gastric bound mucus (ED50 = 31.4 micromol/kg and 27.6 micromol/kg, respectively). In addition, lansoprazole inhibited gastric acid secretion from pylorus-ligated rats (ED50 = 9.8 micromol/kg). Further experiments, performed on rats with ethanol-HCl-induced gastric injury, indicated that the protective effects of lansoprazole were not modified by L-365,260, suramin, N(G)-nitro-L-arginine, or systemic ablation of capsaicin-sensitive sensory nerves, whereas they were partly blocked by indomethacin and fully prevented by N-ethyl-maleimide. In addition, lansoprazole did not modify somatostatin concentrations in gastric mucosa. The present results provide evidence that lansoprazole prevents the necrotic damage of gastric mucosa induced by ethanol-HCl or hemorrhagic shock. According to the rank order of ED50 values, these effects appear to depend mainly on the enhancement of the gastric mucus barrier rather than on the reduction of acid secretion. It is also proposed that an increased production of prostaglandins, as well as an increased availability of sulfhydryl compounds at level of gastric mucosa may account for the gastroprotective effects of lansoprazole.
