BACKGROUND Barrett's oesophagus, columnar metaplasia of the epithelium, is a premalignant condition with a 50-100-fold increased risk of cancer. The condition is caused by chronic gastro-oesophageal reflux. Regression of metaplasia may decrease the cancer risk. AIMS To determine whether elimination of acid gastro-oesophageal reflux induces a regression of metaplastic epithelium. METHODS Six...
Edgardo Effects of a single low dose of ranitidine and effervescent antacids on intragastric acidity in healthy volunteers Acta Gastroenterológica Latinoamericana, Non-profit academic project, developed under the open access initiative Summary Introduction/aims: We hypothesized that a combination of an effervescent antacid and ranitidine could allow immediate and long-lasting increase intragast...
1 Cetamolol is a new 3-adrenoceptor blocking agent shown in animals to have moderate PI -adrenoceptor selectivity and partial agonist activity. 2 In healthy normal volunteers, PI -adrenoceptor blockade was measured as the reduction of exercise-induced tachycardia, systolic blood pressure, and double product at 2, 8, and 24 h after a single oral dose of 10, 25, and 50 mg cetamolol. 3 P1-adrenoce...
the effect of different kinds of surfactants in various concentrations incorporated in an inert matrix, on the release of procainamide hydrochloride, as a cationic model compound, was investigated in this study. sodium lauryl sulfate and sodium stearate as anionic surfactants, cetyl pyridinium chloride and cetyltrimethyl ammonium bromide as cationic and span 60 and tween 80 as non-ionic surfact...
ORF 17583, a histamine H2-receptor antagonist, inhibited gastric acid secretion in pylorus-ligated rats (ED50 = 4.9 mg/kg intraduodenal; 3.4 mg/kg p.o.; and 0.21 mg/kg i.p.) and in total gastric fistula or Heidenhain pouch dogs stimulated by betazole (ED50 = 0.12 mg/kg p.o. and 0.08 mg/kg i.v.), histamine, tetragastrin, bethanechol, 2-deoxy-D-glucose or a meal (ED50 values ranged from 0.11-0.26...
In order to study the importance of gastro-oesophageal reflux (GOR) as a trigger of asthma the effect of inhibition of gastric acid secretion on asthma was assessed in a double-blind, cross-over, placebo-controlled trial over four weeks in 37 children and adolescents (mean age 14 yrs) with bronchial asthma. Ranitidine 300 mg, (150 mg if B.W. was less than 40 kg) was given as a single evening do...
Histamine and calcitonin gene-related peptide (CGRP) contribute to the pain perception. The aim of the present study is to clarify the interaction of histamine and CGRP in the perception of inflammatory pain. The effects of a histamine H1 receptor antagonist (pyrilamine, i.p.), an H2 receptor antagonist (ranitidine, i.p.) and a CGRP antagonist (CGRP 8-37, i.t.) on the formalininduced pain was s...
BACKGROUND Traditionally, proton pump inhibitors are used primarily for patients with esophagitis. However, patients with nonerosive reflux disease may also benefit from these powerful medications. OBJECTIVE To compare the safety and symptom relief efficacy of lansoprazole with ranitidine therapy and with placebo. METHODS In 2 randomized, double-blind, multicenter trials of 901 patients wit...
Ranitidine and metoclopramide are routinely given intravenously before surgical procedures that involve spinal or general anesthesia. Recently, another institution contacted our institution to request stability data to support the practice of routinely mixing ranitidine 50 mg and metoclopramide 10 mg in a 50-mL minibag of normal saline (0.9% sodium chloride) for IV administration before cesarea...
BACKGROUND H2 receptor blockers and proton pump inhibitors reduce intestinal output in patients with short bowel syndrome. AIMS To evaluate the effect of intravenous omeprazole and ranitidine on water, electrolyte, macronutrient, and energy absorption in patients with intestinal resection. METHODS Thirteen patients with a faecal weight above 1.5 kg/day (range 1.7-5.7 kg/day and a median sma...
