As the number of patients receiving a left ventricular assist device increases, physicians must always keep in mind that several conditions can present with non-specific symptoms, such as fever, tachypnoea and confusion. We herein report the case of a left ventricular assist device patient who developed a life-threatening condition with acute hyperthermia, confusion and extremities' clonus and muscle spasms. The patient was diagnosed with serotonin syndrome, attributed to the coadministration of 2 commonly prescribed medications (citalopram and omeprazole)...

BACKGROUND: Proton pump inhibitors (PPIs) are commonly used to treat gastrointestinal diseases. Incidence of hypersensitivity reactions to PPIs has risen, likely because of increased consumption. Their diagnosis is difficult, with skin tests (STs) presenting low sensitivity, making it necessary to perform drug provocation tests (DPTs). The value of in vitro tests for the diagnosis of immediate reaction to PPI is unclear. OBJECTIVE: To analyze the diagnostic value of the basophil activation test (BAT) in a group of patients diagnosed with immediate allergy to omeprazole...

We report the synthesis and enantioseparation characteristics of two novel covalently immobilized deoxycholic acid derivatives as chiral stationary phases for high-performance liquid chromatography. In the structure of the first stationary phase, the 3-position of deoxycholic acid is substituted with a 3,5-dinitrophenylcarbamoyl group and the second one has an additional calix[4]arene attached to the carboxylic group of the deoxycholic acid. The chromatographic performance of the stationary phases was evaluated with enantioseparation of N-(3,5-dinitrobenzoyl)-dl-leucine, N-(3,5-dinitrobenzoyl)-dl-valine, omeprazole, diclofop-methyl, dl-mandelic acid and (RS)-pregabalin...

In this paper, β-cyclodextrin (β-CD) modified gold nanoparticles (AuNPs) coated open tubular column (OT column) was prepared for capillary electrochromatography. The open tubular column was constructed through self-assembly of gold nanoparticles on 3-mercaptopropyl-trimethoxysilane (MPTMS) prederivatized capillary and subsequent modification of thiols β-cyclodextrin (SH-β-CD). Scanning electron microscopy (SEM), transmission electron microscopy (TEM) and ultraviolet visible spectroscopy were carried out to characterize the prepared open tubular column and synthesized gold nanoparticles...

Gastric mucosal cells, particularly parietal and chief cells, are usually affected by exogenous, and endogenous stimuli-induced gastritis. The integrity of these cells and their alterations are involved in the pathogenesis of numerous gastric disorders. Omeprazole, a gastric acid secretion blocker, is commonly used for gastrointestinal diseases due to its antioxidative stress and anti-inflammatory properties. Little is known regarding how omeprazole modulates the re-epithelialized effect on gastric mucosal cells associated with gastrointestinal disorders...

Buchholzia coriacea (B. coriacea) seeds, in folk medicine, have been documented to prevent gastric ulceration though the mechanism is not fully elucidated. To clarify this, the gastro-healing activities were investigated using graded incorporation of B. coriacea seeds in the diet. Male Wistar rats (150-200 g) were divided into 7 groups (n = 15): unulcerated untreated control, ulcerated untreated control, unulcerated B. coriacea low (10%), ulcerated B. coriacea low (10%), nulcerated B. coriacea high (25%), ulcerated B...

Cynomolgus monkeys (Macaca fascicularis, Old World Monkeys) and common marmosets (Callithrix jacchus, New World Monkeys) have been widely, and expectedly, used as non-human primate models in drug development studies. Major drug-metabolizing cytochrome P450 (P450) enzymes information is now available that supports these primate species as animal models, and it is established that multiple forms of cynomolgus monkey and common marmoset P450 enzymes have generally similar substrate recognition functionality to human P450 enzymes...

OBJECTIVES: The incidence of reduced susceptibility to tigecycline (TIG) is increasing. This study aimed to analyse the in vitro activity of TIG against Enterococcus spp. isolates recovered from hospitalised patients and to evaluate the effect of omeprazole on the in vitro antimicrobial activity of TIG against several enterococcal species. METHODS: A total of 67 Enterococcus clinical isolates were identified by MALDI-TOF/MS and multiplex PCR. Minimum inhibitory concentrations (MICs) of TIG alone and in combination with omeprazole (10, 30 and 60mg/L) were determined by broth microdilution...

RATIONALE: Clostridium difficile infection (CDI) is a symptomatic infection due to the spore-forming bacterium, C. difficile. Asymptomatic C. difficile colonization is the stage in absence of symptoms, with a prevalence of 1.4% to 21% on hospital admission. Proton-pump inhibitors (PPIs) was implicated as a novel potential contributor to CDI. PPIs injection could make asymptomatic C. difficile colonization progress to C. difficile associated diarrhea (CDAD). PATIENT CONCERNS: A postoperative colon cancer patient, who had been taking omeprazole for 4 years after operation, got asymptomatic C...

Omeprazole is a proton pump inhibitor used to treat the symptoms of gastro esophageal reflux disease, ulcers, excess stomach acid, infection with Helicobacter pylori, and to control the gastric side effects of various drugs. The approved dosage forms in the U.S. are powder in compounding kits, delayed-release granules for oral suspension, oral delayed-release tablets, and oral delayed-release capsules. An extemporaneously compounded unsweetened oral liquid method, published in the International Journal of Pharmaceutical Compounding, was found to be commonly used by pharmacists...

Most of pain-relieving agents in chronic pancreatitis are nonspecific and unpredictable. Omeprazole induces hypergastrinemia due to reduced gastric acidity. Raised serum gastrin, in turn, modulates to reduce secretin level. Secretin is responsible for secretion of almost 80 % bicarbonate-rich pancreatic juice from the ductular epithelium without affecting enzyme output. It is a prospective randomized study in patients with CT-confirmed chronic pancreatitis. The control group got the standard care and 60 mg of omeprazole twice daily was added to the test group...

BACKGROUND: The extents of generic-reference and generic-generic average bioequivalence and intra-subject variation of on-market drug products have not been prospectively studied on a large scale. METHODS: We assessed bioequivalence of 42 generic products of 14 immediate-release oral drugs with the highest number of generic products on the Saudi market. We conducted 14 four-sequence, randomized, crossover studies on the reference and three randomly-selected generic products of amlodipine, amoxicillin, atenolol, cephalexin, ciprofloxacin, clarithromycin, diclofenac, ibuprofen, fluconazole, metformin, metronidazole, paracetamol, omeprazole, and ranitidine...

Silver and silver oxides are gaining interest in medical applications for their prominent antibacterial and antimicrobial potentials. Recent studies suggest that nanosilver oxide has remarkable anti-inflammatory effects and enhances wound healing. Nevertheless, its effect on gastric ulcer has not yet been illustrated. Thus the current study aimed to explore the prospect protective effect of nanosilver oxide against indomethacin-induced gastric ulcer. A new approach has been followed to synthesize nanosilver oxide...

The newly synthesized, 3,4,5-Trihydroxy-N 0-[(2-methyl-1H-indol-3-yl)-methylidene] benzohydrazide (TIBH), is an indole and gallic acid derivative. The aim of this research investigation was to evaluate the acute toxicity and the ulcer prevention potential of TIBH in HCl/Ethanol-induced gastric ulcer rat model. Six groups of rats were orally received 5ml/kg of vehicle (1 % Carboxy methyl cellulose) for the normal and ulcer control groups each, Omeprazole (20mg/kg) for positive control, 50 mg/kg, 100 mg/kg and 200 mg/kg of TIBH for experimental groups, respectively...

Gastroesophageal reflux disease (GERD) is frequently seen during pregnancy. In the medical treatment of pregnant women with GERD, alginic acid and sucralfate can be used. Calcium- and magnesium-based antacids can also be used, particularly for patients with preeclampsia. In particular, ranitidine -a histamine-2 receptor blocker- is preferred. In the case of non-responsiveness to the abovementioned treatments, proton pump inhibitors (PPIs), except omeprazole, can be given considering the benefit-harm ratio for the mother and fetus after the first trimester...
