The influence of secretory transporters on intestinal permeability characteristics of the H2 receptor antagonists ranitidine and cimetidine was studied in Caco-2 monolayers and rat intestinal mucosa mounted in Ussing chambers. Both drugs exhibited vectorial transport across rat ileum with significantly greater (2-4-fold) permeability in the serosal-to-mucosal than the mucosal-to-serosal directi...
Depression and anxiety were measured during the course of a double-blind, placebo-controlled trial of the histamine H2-receptor antagonist, ranitidine (150 mg twice daily), in patients suffering from duodenal ulcer but free of systemic disease. There were 25 patients in the ranitidine group (mean age: 33.2 years) and 28 in the placebo group (mean age: 37.2 years). In both groups there was a hig...
background: this study aimed to compare intermittent intravenous (iv) pantoprazole and ranitidine for control of gastric acid secretion and the possible prevention of upper gastrointestinal bleeding (ugib) in critical care patients. methods: this was a randomized, double blind clinical trial study of iv pantoprazole (40 mg every12 hour) or intermittent iv ranitidine (50 mg bolus every 8 hour) i...
Research advances during recent years offer new insight into therapy and the prevention of gastrointestinal ulcers by using medicinal plants. Flavonoids, tannins, triterpenoids, fatty acids and essential oils are among the most effective herbal constituents that have potential antiulcerogenic properties, and most of them could be found in Zataria multiflora. Z. multiflora</e...
A new drug delivery system for H2 receptor antagonist Ranitidine hydrochloride, was developed utilizing both the concepts of adhesiveness and of flotation, in order to obtain a unique drug delivery system which could remain in the stomach for a much longer period of tim Floating-Mucoadesive tablets of Ranitidine hydrochloride were developed to prolong its release and improve bioavailability. Ra...
The efficacy of preanaesthetic intravenous cimetidine versus ranitidine with and without metoclopramide for acid aspiration prophylaxis was assessed in 60 morbidly obese patients in a double-blind manner. Group 1 patients received cimetidine 300 mg + saline. Group 2 patients received cimetidine 300 mg + metoclopramide 10 mg. Group 3 patients received ranitidine 100 mg + saline. Group 4 patients...
Human organic cation transporters (hOCTs) are expressed in organs of drug absorption and elimination and play an important role in the uptake and elimination of xenobiotics. The purpose of this study was to evaluate the substrate and inhibitory activity of the H2-receptor antagonists ranitidine and famotidine toward hOCTs and to determine the hOCT isoforms involved in the absorption and elimina...
OBJECTIVE To evaluate clinical, Quality of Life (QoL) and medical cost outcomes in patients with symptomatic reflux esophagitis (RE) receiving different "triple combination therapy". METHODS A multicenter medical effectiveness trial conducted in 10 hospitals of 5 regions in Zhejiang Province. 248 patient-volunteers were assigned to 8 weeks of "triple combination therapy" with Lansoprazole plu...
Proton pump inhibitors and H2 receptor antagonists, which are commonly used to treat peptic ulcer and gastroesophageal reflux diseases, are associated with a low incidence of adverse reactions. We report 3 cases of anaphylactic reactions induced by lansoprazole or ranitidine diagnosed in a population of 8304 first-referral patients over a 13-year period. Cutaneous sensitivity to famotidine, ran...
Aim: To test the hypothesis that the volume and pH of the gastric contents in patients pre-treated with Tramadol will be comparable to those patients treated with Ranitidine. Methods: Sixty ASA II parturients undergoing elective Caesarean section were included in a randomized double-blind study. The patients were randomly allocated to receive intramuscular tramadol 100mg (n=30) or ranitidine 50...
