Eosinophilic Esophagitis (EoE) is a chronic condition characterized by esophageal dysfunction including dysphagia, abdominal pain and eosinophilic inflammation (>15/HPF) of the esophagus. At present, the most commonly used treatment for the management of EoE are steroids, both systemic as well as tropical, and dietary elimination. The advantage of the systemic steroids include ease of administration, rapid response, and very high response rate. However, poor solubility and the adverse effect related to prolonged steroid use are well documented...

Ranitidine (brand name: Zantac), an acid reducer, belongs to histamine-2 receptor antagonists. Since 1981, even though several adverse effects of this drug were reported in the body, still, its effects on human sperm parameters have yet to be confirmed. In this work, we attempted to measure sperm motility, sperm vitality and activity of seminal creatine kinase in the ejaculated human semen (n = 31) in the presence of ranitidine at a range of concentrations (0.1, 0.3, 0.6, 0.9 and 1.2 μg/ml) compared with control (without ranitidine)...

Proton pump inhibitors (PPIs) are the mainstay of treatment for many gastric acid-related diseases with a relatively safe drug profile. One of the rare side effects is PPI-induced bullous pemphigoid. We describe a case of new-onset bullous pemphigoid on initiation of lansoprazole for esophagitis after a nationwide Zantac recall. This condition can improve with the cessation of PPI and the use of corticosteroids. However, it poses a significant challenge to the management of gastroesophageal reflux disease by limiting available pharmacologic options...

Excipients play an important role in pharmaceutical formulations. Many clay minerals, because of their large specific surface area and inert behaviour in reactions with active ingredients, are commonly used as excipients. In this study, the uptake of ranitidine (RT), the active ingredient of Zantac, on and released from palygorskite (Pal), kaolinite (Kao), and talc was evaluated under different physicochemical conditions. The results showed that the uptake of RT on these minerals was limited to the external surface areas only...

OBJECTIVE: Cerebral ventricular shunt failure is common and presents with symptoms that range from headaches to death. The combination of Diamox (acetazolamide), Decadron (dexamethasone), and Zantac (ranitidine) (DDZ) is used at our institution to medically stabilize pediatric patients presenting with symptomatic shunt failure before shunt revision. We describe our experience of this drug combination as a temporizing measure to decrease symptoms associated with shunt failure. METHODS: We performed a single-center retrospective chart review of patients younger than 18 years with ventricular shunt failure who underwent a shunt revision between January 2015 to October 2017 and received DDZ before surgery...

Ranitidine is an H2 antihistamine used as an off-label therapy for recalcitrant verruca vulgaris. We describe a man who developed a sleep disturbance after initiating therapy with ranitidine and review similar adverse effects associated with other drugs in this class. The patient was a 40-year-old man with an eight-year history of a wart on his right plantar foot that was recalcitrant to several topical therapies. Adjunctive treatment with ranitidine 150 mg twice daily was initiated. He developed sleep disturbance with bizarre dreams and gastrointestinal symptoms...

BACKGROUND: Ranitidine (Zantac®) is a H2-receptor antagonist commonly used for the treatment of acid-related gastrointestinal diseases. Ranitidine was reported to be a substrate of the organic cation transporters OCT1 and OCT2. The hepatic transporter OCT1 is highly genetically variable. Twelve major alleles confer partial or complete loss of OCT1 activity. The effects of these polymorphisms are highly substrate-specific and therefore difficult to predict. The renal transporter OCT2 has a common polymorphism, Ala270Ser, which was reported to affect OCT2 activity...

Spectral studies revealed the presence of a specific arrangement of 5-hydroxymethylfurfural (5-HMF) molecules in solution as a result of a hydrogen-bonding network, and this arrangement readily facilitates the aging of 5-HMF. Deterioration of the quality of this platform chemical limits its practical applications, especially in synthesis/pharma areas. The model drug Ranitidine (Zantac®) was synthesized with only 15 % yield starting from 5-HMF which was isolated and stored as an oil after a biomass conversion process...

BACKGROUND: Ranitidine is widely used for gastroesophageal reflux disease (GERD) in children, but optimal dosing is unclear. We compared effects of weight-based doses of oral ranitidine on gastric pH in children with clinical GERD. METHODS: Children ages 4-11 years with clinical GERD were enrolled in a multi-center prospective randomized study comparing a fixed dose of ranitidine (Zantac 75) with placebo after an overnight fast; gastric pH was measured for 6 h after the fixed dose (Phase 1)...

OBJECTIVE: This case study reports on chiropractic care for pregnancy-related heartburn. The purpose of this article is to relate the benefit of chiropractic treatment for one individual, to contrast chiropractic management with the biomedical standard of care for pregnancy-related heartburn, and to point to potential epigenetic implications of the standard of care. CLINICAL FEATURES: A 32-year-old woman who was 24 weeks pregnant presented with persistent heartburn that she was treating with ranitidine (Zantac®) and calcium carbonate (Tums®) daily at the initiation of chiropractic care...

The aim of study was to compare the bioavailability of ranitidine obtained from either Ranitidine (300 mg tablet; LPH® S.C. LaborMed Pharma S.A. Romania: the test formulation) and Zantac® (300 mg tablet; GlaxoSmithKline, Austria: the reference formulation). Twelve, Romanian, healthy volunteers were enrolled in the study. An open-label, two-period, crossover, randomized design was used. Plasma levels of ranitidine were determined using the validated, high-pressure liquid chromatography (HPLC) method. The physiologically motivated time-delayed model was used for the data evaluation and a paired Student's t-test and Schuirmann's two one-sided tests were carried out to compare parameters...

OBJECTIVE: The study proposes to investigate the pharmacological efficacy of four commonly used acid inhibitory drugs. The effect on 24 hour gastric pH of seven days treatment was assessed for two omeprazole preparations, Losec(R) 20 mg (Hassle) and Lómex(R) 20 mg, (Omega Farma) and two H2 blockers, famotidine 40 mg (Famex(R), Omega Farma) and ranitidine 300 mg (Zantac(R), Glaxo). MATERIAL AND METHODS: Sixteen healthy volunteers participated in each experiment comparing blindly Losec(R) / Lómex(R) and Famex(R) / Zantac(R)...

PURPOSE: Evidence is needed to guide NICU use of lansoprazole (Prevacid), ranitidine (Zantac), and metoclopramide (Reglan). As a step toward that goal, we conducted a historic cohort analysis of all patients who received any of these medications in 4 Intermountain Healthcare NICUs during the year 2006. SUBJECTS: Data were obtained from all patients admitted between January 1 and December 31, 2006, to any of 4 Intermountain Healthcare NICUs. DESIGN: This was a retrospective descriptive design...

INTRODUCTION: Ranitidine hydrochloride (Zantac), a histamine-2-receptor antagonist, is a widely used medication with an excellent safety record. Anaphylactic reaction to ranitidine is an extremely rare event and a related death has never been described in the literature. CASE PRESENTATION: We present the clinical history, histological and toxicological data of a 51-year-old man with negative anamnesis for allergic events, who died suddenly after the intravenous administration of one phial of Zantac 50 mg prescribed as a routine post-surgical prophylaxis for stress ulcer...

An 80-year-old male who developed a generalized papular erythema-type drug eruption after being treated with ranitidine hydrochloride is herein reported. The duration from the intake of the medicine to the onset of the eruption was 3 days, and the eruption remained unchanged for a week after withdrawal of the medicine and even after the eruption itself was treated. A diagnosis of drug eruption by ranitidine hydrochloride was confirmed based on a strongly-positive reaction of a drug-induced lymphocyte stimulation test (DLST)...

BACKGROUND: Many investigations have focused on optimal doses/schedules since regulatory agency approval of paclitaxel (Taxol). Paclitaxel is generally administered at doses of 175-225 mg/m2 over 3 hours or 135-175 mg/m2 over 24 hours, every 3 weeks. The purpose of this study was to simplify administration and render it suitable and practical in the outpatient setting. Using this rationale, the duration of administration was decreased to one hour, with a minimized premedication regimen...
