OBJECTIVE This 1-year study compared the cost effectiveness of omeprazole and ranitidine when used as initial therapy in an intermittent treatment strategy for the management of patients with symptomatic gastro-oesophageal reflux disease with or without erosive oesophagitis. DESIGN AND SETTING A prospective health economic analysis was conducted alongside an international multicentre randomis...

The effect of ranitidine and cisapride on acid reflux and oesophageal motility was investigated in 18 patients with endoscopically verified erosive reflux oesophagitis. Each patient was treated with placebo, ranitidine (150 mg twice daily), and ranitidine (150 mg twice daily) plus cisapride (20 mg twice daily) in a double blind, double dummy, within subject, three way cross over design. Oesopha...

The photochemical fates of the histamine H2-receptor antagonists cimetidine and ranitidine were studied. Each of the two environmentally relevant pharmaceuticals displayed high rates of reaction with both singlet oxygen (1O2, O2(1delta(g))) and hydroxyl radical (*OH), two transient oxidants formed in sunlit natural waters. For cimetidine, the bimolecular rate constant for reaction with *OH in w...

Ranitidine hydrochloride has been extensively used in the treatment of diverse gastrointestinal disorders. This drug is a selective, competitive histamine H2-receptor antagonist and established as a potent inhibitor of gastric acid secretion. Owing to its favourable efficacy and tolerability profiles, this drug has emerged as a first-line agent when suppression of gastric acid secretion is indi...

The economic evaluation of new medicines is increasingly important for pricing, registration and selection for use. A decision-analytic strategy was performed to assess the economic impact of antacids alone (phase I therapy), and in combination with either omeprazole, 20 mg once daily, or ranitidine, 150 mg twice daily, for patients with persistent, symptomatic gastro-oesophageal reflux disease...

UNLABELLED : Ranitidine is a widely used drug and is known to be well tolerated. This case report illustrates a severe anaphylactic reaction after a single intravenous dose of 50 mgs of ranitidine and highlights this unusual but life threatening adverse reaction. THE PATIENT A 56 year old female with acute pancreatitis and a known allergy to metronidazole and buscopan developed an anaphylaxis...

Ocimum sanctum is a medicinal plant which has been used studied for various properties and used in various conditions.In the present study, ocimum sanctum was investigated for its effects against swimming stress induced ulcers in albino rats. The effects were compared with ranitidine. The leaf extract of ocimum sanctum showed significant antiulcer activity in the dose of 100 mg/kg and 200 mg/kg...

In a double blind endoscopically controlled study, 100 patients with gastric ulcers were treated with either ranitidine or ranitidine plus Caved-S. On single therapy, 58% of ulcers were healed at four weeks, 92% at eight weeks and 96% at 12 weeks. Combination therapy did not alter the healing rate, nor improve on the control of dyspeptic symptoms. No difference in healing rate was found between...

A dose/response study has been carried out in seven patients with endoscopically proven duodenal ulcers in symptomatic remission, measuring intragastric pH and gastric acid output overnight after a bedtime dose of ranitidine (75 mg, 150 mg, and 300 mg); and the results have been compared with placebo and with bedtime cimetidine 400 mg. The currently recommended ranitidine maintenance dose (150 ...

The pharmacokinetic parameters of domestic and imported ranitidine hydrochloride tablets (Ranitidine, formulated and manufactured by Kharazmi Pharmaceuticals, Iran, and Zantac ? manufactured by Glaxo, UK) were measured in 14 healthy subjects following oral administration of a single 300-mg dose of each brand and compared for bioequivalence evaluation. The pharmaceutical equivalency of both fo...
