Tyler Werbel, Philip R Cohen
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...

Christos Kosmas, Nicolas Tsavaris
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...

BACKGROUND: Ageing can be associated with poor dietary intake, reduced nutrient absorption, and less efficient utilization of nutrients. Loss of memory and related cognitive function are also common among older persons. This study aimed to measure the prevalence of inadequate vitamin status among long-term care patients and determine if an association exists between vitamin status and each of three variables; cognitive function, vitamin supplementation, and medications which alter gastric acid levels...

Gastrointestinal symptoms are often an early and prominent manifestation of Fabry disease, an X-linked inborn error of metabolism caused by the deficient activity of the lysosomal enzyme, alpha-galactosidase A. This enzyme deficiency results in the progressive accumulation of globotriaosylceramide and other glycosphingolipids in tissue lysosomes throughout the body. In classically affected patients, glycosphingolipid accumulation in the vascular endothelium eventually culminates in life-threatening renal, cardiac, and cerebrovascular disease...

Possums are a wildlife vector of bovine tuberculosis in New Zealand. Vaccination of possums with BCG is being considered as a measure to control the spread of bovine tuberculosis to cattle and deer. Delivery via oral bait is feasible but BCG is degraded in the stomach. The aim was to determine whether ranitidine (Zantac) would reduce gastric acidity and enhance the efficacy of intragastrically administered BCG. A dose of 75 mg reduced gastric acidity for at least 4 h. Thus, possums were vaccinated intragastrically with BCG after receiving 75 mg ranitidine or ranitidine or BCG alone, as controls, before challenge with virulent Mycobacterium bovis...

Ranitidine bismuth citrate (Pylorid, Tritec) is a novel drug which heals peptic ulcers and when co-prescribed with either clarithromycin or amoxycillin eradicatesHelicobacter pylori. In controlled clinical studies it was well-tolerated when given alone or when co-prescribed with either antibiotic. Data from 20 clinical studies are reported in this analysis of safety with almost 5000 patients having received ranitidine bismuth citrate (200, 400, or 800 mg twice daily). The incidence of adverse events reported with this new drug, either alone or with an antibiotic, was not different from or lower than in patients given placebo and was independent of the dose of ranitidine bismuth citrate tested...
