A physiologically based human kinetic model (PBHKM) was used to predict the in vivo ibuprofen dose leading to the same concentration-time profile as measured in cultured human hepatic cells (Truisi et al. in Toxicol Lett 233(2):172-186, 2015). We parameterized the PBHKM with data from an in vivo study. Tissue partition coefficients were calculated by an algorithm and also derived from the experimental in vitro data for the liver. The predicted concentration-time profile in plasma was in excellent agreement with human experimental data when the liver partition coefficient was calculated by the algorithm (3...

Eosinophilic myocarditis (EM) is a rare and potentially fatal disease if left untreated. Because the disease can have a delayed presentation and can appear even after 2 years, its underlying causes often remain unknown. We report the case of a 63-year-old man with an atypical clinical presentation of hypersensitive EM and significant coronary artery disease, which was confirmed through coronary angiography. The patient was treated with hydrochlorothiazide (12.5 mg once daily for 2 years) and budesonide/formoterol (160/4...

BACKGROUND: Metformin is a widely used and safe antidiabetic drug that has recently been shown to possess analgesic properties in models of inflammatory pain. Because various arthritic inflammatory disorders are highly prevalent in diabetic patients, we aimed to examine the type of interaction between metformin and several conventional and adjuvant analgesic drugs (ibuprofen, aspirin, tramadol, and pregabalin) in a rat model of somatic inflammatory hyperalgesia. METHODS: Inflammation of the rat hind paw was induced by an intraplantar injection of carrageenan (0...

The aqueous methanolic extract of stem part of Berberis calliobotiys (AMEBC) was evaluated for anti-inflammatory, analgesic and antipyretic activities in albino mice. Anti-inflammatory activity was evaluated by using carrageenan and albumin induced paw edema, while the analgesic effect was assessed by using formalin-induced paw licking and acetic acid induced abdominal writhing in mice. The brewer's yeast-induced pyrexia model was used for antipyretic investigation. Ibuprofen (40 mg/kg) was used as a standard drug in all the three models...

INTRODUCTION: Kawasaki disease is an acute vasculitis which occurs primarily in children under the age of 5. The etiology of the disease is still unknown. Diagnostic criteria for Kawasaki disease are fever and at least four of the five additional clinical signs. Incomplete Kawasaki disease should be taken into consideration in case of all children with unexplained fever for more than 5 days, associated with 2 or 3 of the main clinical findings of Kawasaki disease. The diagnosis of incomplete Kawasaki disease is based on echocardiographic findings indicating the involvement of the coronary arteries...

Nonsteroidal anti-inflammatory drugs (NSAIDs), which are globally prescribed, exhibit mainly anti-inflammatory and analgesic effects but also can cause adverse effects including gastrointestinal erosions, ulceration, bleeding, and perforation. The purpose of this study was to investigate surrogate biomarkers associated with the gastrointestinal (GI) damage caused by NSAID treatment using pattern recognition analysis of (1)H-nuclear magnetic resonance ((1)H NMR) spectra of rat urine. Urine was collected for 5h after oral administration of the following NSAIDs at low or high doses: acetylsalicylic acid (10 or 200mgkg(-1)), diclofenac (0...

INTRODUCTION: The approved analgesic and anti-inflammatory drugs ibuprofen and indometacin block the small GTPase RhoA, a key enzyme that impedes axonal sprouting after axonal damage. Inhibition of the Rho pathway in a central nervous system-effective manner requires higher dosages compared with orthodox cyclooxygenase-blocking effects. Preclinical studies on spinal cord injury (SCI) imply improved motor recovery after ibuprofen/indometacin-mediated Rho inhibition. This has been reassessed by a meta-analysis of the underlying experimental evidence, which indicates an overall effect size of 20...

BACKGROUND: Pain, one of the cardinal signs of inflammation, is the most common clinical manifestations of arthritis. Conventional pain relief therapy heavily relies on the use of prescription and over the counter nonsteroidal anti-inflammatory drugs as the first line of defense where their long-term usage causes deleterious gastrointestinal and cardiovascular-related side-effects. Hence, there is an equivocal need for evidence-based safer and efficacious alternatives from natural sources to overcome the most prominent and disabling symptoms of arthritis...

High-dose ibuprofen, an effective anti-inflammatory therapy for the treatment of cystic fibrosis (CF), has been shown to preserve lung function in a pediatric population. Despite its efficacy, few patients receive ibuprofen treatment due to potential renal and gastrointestinal toxicity. The mechanism of ibuprofen efficacy is also unclear. We have previously demonstrated that CF microtubules are slower to reform after depolymerization compared with respective wild-type controls. Slower microtubule dynamics in CF cells are responsible for impaired intracellular transport and are related to inflammatory signaling...

The usage of fluconazole and amphotericin B in clinical settings is often limited by, among other things, drug resistance development and undesired side effects. Thus, there is a constant need to find new drugs to better manage fungal infections. Toward this end, the study described in this paper considered the repurposing of aspirin (acetylsalicylic acid) and ibuprofen as alternative drugs to control the growth of cryptococcal cells. In vitro susceptibility tests, including a checkerboard assay, were performed to assess the response of Cryptococcus neoformans and Cryptococcus gattii to the above-mentioned anti-inflammatory drugs...

Dexibuprofen-loaded PEGylated PLGA nanospheres have been developed to improve the biopharmaceutical profile of the anti-inflammatory drug for ocular administration. Dexibuprofen is the active enantiomer of ibuprofen and therefore lower doses may be applied to achieve the same therapeutic level. According to this, two batches of nanospheres of different drug concentrations, 0.5 and 1.0mg/ml respectively, have been developed (the latter corresponding to the therapeutic ibuprofen concentration for inflammatory eye diseases)...

A chiral high-performance liquid chromatography method was developed for the simultaneous determination of ibuprofen enantiomers in dog plasma. It was used to study the pharmacokinetics in the Beagle dog after intravenous administration of racemic-ibuprofen, S-ibuprofen and R-ibuprofen. Ketoprofen was chosen as the internal standard. After a simple precipitation using methanol as the precipitating solvent, both analytes and IS were separated on a Kromasil 100-5CHI-TBB chiral column (250 mm x4.6 mm, 5 μm) with isocratic elution using acetonitrile - 20 mmol x L(-1) phosphate buffer (pH 3...

BACKGROUND AND PURPOSE: Pulmonary disease is the main cause of morbidity and mortality in cystic fibrosis (CF) patients due to exacerbated inflammation. To date, the only anti-inflammatory drug available to CF patients is high-dose ibuprofen, which can slow pulmonary disease progression, but whose cyclooxygenase-dependent digestive adverse effects limit its clinical use. Here we have tested sulindac, another non-steroidal anti-inflammatory drug with an undefined anti-inflammatory effect in CF airway epithelial cells...

A patent ductus arteriosus (PDA) is associated with several adverse clinical conditions. Several strategies for PDA treatment exist, although data regarding the benefits of PDA treatment on outcomes are sparse. Moreover, the optimal treatment strategy for preterm neonates with PDA remains subject to debate. It is still unknown whether and when PDA treatment should be initiated and which approach (conservative, pharmacologic, or surgical) is best for individual patients (tailored therapies). This article reviews the current strategies for PDA treatment with a special focus on recent developments such as oral ibuprofen, high-dose regimens, and the use of paracetamol (oral, intravenous)...
