BACKGROUND The inhibition of gastric acid secretion with ranitidine is frequently prescribed off-label to newborns admitted to neonatal intensive care units (NICU). Some studies show that the use of inhibitors of gastric acid secretion (IGAS) may predispose to infections and necrotising enterocolitis (NEC), but there are few data to confirm this association. This study aimed to compare the rate...

The effectiveness of sodium citrate and sodium citrate/ranitidine were compared in two randomised groups of elective caesarean patients during the various phases of anaesthesia. The mean pH values (3.5, 3.3, 3.6) were lower in the citrate group compared to the citrate/ranitidine group (6.1, 6.3, 5.9). The percentage of patients with pH values less than 2.5 was 40% in the citrate group compared ...

Objective: This prospective, randomized, double-blind study was performed to evaluate the effects of intravenous co-administration of metoclopramide and ranitidine on preoperative gastric contents in patients receiving general anesthesia for elective laparoscopic cholecystectomy surgery, a procedure with high risk of aspiration. Material and Methods: Eighty ASA physical status I-II consenting p...

In a double-blind, placebo controlled and randomised secretory study the effectiveness of pirenzepine, ranitidine, and their combination was compared intraindividually in eight healthy subjects receiving intravenous bolus injections. Pirenzepine (0.15 mg/kg) plus ranitidine (0.6 mg/kg) suppressed peptone-stimulated gastric acid secretion from 69 +/- 11 to 2 +/- 0.4 mmol H+/3 h; the mean percent...

We previously reported that ranitidine, an H(2) receptor antagonist, inhibited neutrophil activation in vitro and in vivo, contributing to reduce stress-induced gastric mucosal injury in rats. In this study, we examined whether ranitidine would reduce ischemia/reperfusion-induced liver injury, in which activated neutrophils are critically involved, in rats. We also examined the effect of famoti...

BACKGROUND Levodopa (l-dopa) remains the best drug in the treatment of Parkinson's disease (PD). Unfortunately, long-term l-dopa caused motor complications, one of which is l-dopa-induced dyskinesia (LID). The precise mechanisms of LID are not fully understood. We have previously reported that ranitidine could reduce LID by inhibiting the activity of protein kinase A pathway in a rat model of P...

AIM To determine the optimal doses of ranitidine for both preterm and term infants. METHOD The effect of ranitidine treatment was measured from the long-term intraluminal gastric pH in 16 preterm (gestational age under 37 weeks) and term infants treated in neonatal intensive care. The infants received three different bolus doses of ranitidine: 0.5 mg, 1.0 mg, and 1.5 mg per kilogram of body w...

This placebo-controlled trial compared the effects of preoperative, intravenous cimetidine (300 mg) or ranitidine (50 mg) on gastric pH and gastric volume in 31 adult patients requiring general anesthesia. The elapsed time from drug administration to initial gastric sampling did not differ significantly between ranitidine (45 minutes), cimetidine (48 minutes), or placebo (52 minutes) treated pa...

This study investigated whether ulcer prevention would be greater with the combined use of an acid-inhibiting agent, ranitidine, given together with a mucosal-protective agent, sucralphate. Duodenal ulcers were induced in rats with the secretagogues pentagastrin and bethanechol. Subtherapeutic doses of ranitidine (5 mg/kg/6 hours) and sucralphate (50 mg/6 hour) yielded an ulcer index of 4.0 and...
