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...

BACKGROUND Avipattikar churna, a poly-herbal formulation, is one of the popular ayurvedic formulations which is used for peptic ulcer diseases but the scientific documentation with regards to its effect for the indication is lacking. AIMS This study was carried out to evaluate the anti-secretory and the anti-ulcerogenic activities of the churna and to compare its activity with that of ranitid...

BACKGROUND AND PURPOSE Administration of histamine receptor antagonists has been reported to produce contradictory results, either reducing or increasing neural damage induced by ischemia. In this study, we investigated the neuroprotective effects of histamine H2-receptor antagonists in an "in vitro" model of ischemia. METHODS Cultured rat brain cortical neurons were exposed to oxygen-glucose...

Background: Previous investigations have revealed, cimetidine, a histamine H2-receptor antagonist, show radioprotective effects against gammaand neutron-induced micronuclei in bone marrow erythrocytes. In this study, the anticlastogenic effects of famotidine and ranitidine, which act similar to cimetidine as histamine H2-receptor antagonists, was investigated. Materials and Methods: Balb/c male...

This study discusses efforts made to design drug-delivery system based on superporous hydrogel composite for sustained delivery of ranitidine hydrochloride. The characterization studies involve measurement of apparent density, porosity, swelling studies, mechanical strength studies, and scanning electron microscopy. Scanning electron microscopic images clearly showed the formation of interconne...

New ranitidine hydrochloride (RaCl)-selective electrodes of the conventional polymer membrane type are described. They are based on incorporation of ranitidine-tetraphenylborate (Ra-TPB) ion-pair or ranitidine-phosphotungstate (RaPT) ion-associate in a poly(vinyl chloride) (PVC) membrane plasticized with dioctylphthalate (DOP) or dibutylphthalate (DBP). The electrodes are fully characterized in...

The proton pump inhibitor, omeprazole, surprisingly resulted in higher rates of proximal duodenal mucosal bicarbonate secretion than previously reported using an H2 receptor antagonist for gastric acid inhibition. Gastroduodenal perfusions were performed in healthy volunteers to evaluate whether this incidental finding is explained by more potent gastric acid inhibition by omeprazole or might b...

BACKGROUND/AIMS The aim of this study was to investigate the effects of the H2 receptor antagonists famotidine and ranitidine on lower esophageal sphincter pressure in the rat isolated lower esophageal sphincter preparation contracted with carbachol. MATERIALS AND METHODS Lower esophageal sphincter tissues of eight rats for each group were placed in a standard organ bath. After contraction wi...

BACKGROUND Single-patient trials (SPTs) are randomized, often multiple-crossover trials where patients serve as their own control to determine their appropriate treatment. Historically, SPTs have been individually customized, requiring significant time and cost for execution. The patient.s progress is tracked and evaluated in a blinded, multiple-crossover design comparing different therapies. S...
