The gastrointestinal mucosa provides the first protective barrier for digested food and xenobiotics, which are easily attacked by toxic substances. Non-steroidal anti-inflammatory drugs (NSAIDs), including aspirin, diclofenac, indomethacin, and ketoprofen, are widely used in clinical medicine, but these drugs may cause oxidative stress, leading to gastrointestinal damage, such as ulcers. Lansoprazol, omeprazole, and other clinical drugs are widely used to treat duodenal and gastric ulcers and haven been shown to have multiple biological functions, such as antioxidant activity and the ability to upregulate antioxidant enzymes in vivo...

Alzheimer's disease (AD) represents a substantial unmet need, due to increasing prevalence in an ageing society and the absence of a disease modifying therapy. Epidemiological evidence shows a protective effect of non steroidal anti inflammatory (NSAID) drugs, and genome wide association studies (GWAS) show consistent linkage to inflammatory pathways; both observations suggesting anti-inflammatory compounds might be effective in AD therapy although clinical trials to date have not been positive. In this study, we use pathway enrichment and fuzzy logic to identify pathways (KEGG database) simultaneously affected in both AD and by NSAIDs (Sulindac, Piroxicam, Paracetamol, Naproxen, Nabumetone, Ketoprofen, Diclofenac and Aspirin)...

A two-dimensional achiral-chiral LC-LC method in heart-cut mode for ketoprofen and its enantiomeric fraction determination was proposed. A C8 column was used in the first dimension, and the chiral column was an α1-acid glycoprotein. The mobile phase of the chiral system was optimized by a factorial design. The effect of temperature on retention and on enantiomeric resolution was studied. Particular attention was paid to mobile phase compatibility for the two columns and to transferring time, using ketoprofen standards...

Dexketoprofen trometamol (DT), a nonsteroidal anti-inflammatory drug, is a highly water-soluble salt and active enantiomer of rac-ketoprofen. Its parenteral form is commonly used for acute pain management in emergency departments of our country. Side effects such as diarrhea, indigestion, nausea, stomach pain, and vomiting may be seen after the use of DT. Anaphylactic shock (AS) secondary to infusion of DT is very rare and, to our knowledge, it is the first case report describing this side effect. This case report was presented to emphasize that AS may be seen after the use of DT...

Using a sunscreen-based photocage, we have demonstrated that it is possible to prevent photodegradation of a bioactive compound and to achieve its controlled photorelease. The concept has been proven linking avobenzone, one of the most important UVA blockers, to ketoprofen, which is a representative example of a photosensitive drug.

Various preclinical/clinical studies support the effectiveness of ketoprofen in periodontitis; however, the literature reveals that novel delivery systems have been less explored for the drug in periodontitis. The current investigation aims to explore the potential of a pro-vesicular approach-based proniosomal drug delivery of ketoprofen for its effectiveness and validation in experimental periodontal disease (EPD). Formulations were developed using I-optimal mixture design. Developed formulations were characterized for entrapment efficiency, vesicle size, and in vitro drug release...

In this work, the traditional liquid phase microextraction (LPME) has been miniaturized into a microfluidic device (μLPME) where liquid phase microextraction is combined with an HPLC procedure. This integration enables extraction and determination of acid drugs by μLPME and HPLC, respectively. The analytes selected for the test are five widely used non-steroidal anti-inflammatory drugs (NSAIDs): salicylic acid (SAC), ketoprofen (KTP), naproxen (NAX), diclofenac (DIC) and ibuprofen (IBU). They have successfully been detected in biological (urine and saliva) and environmental (lake and river water) samples with excellent clean up, high extraction efficiency and good enrichment factor under stopped-flow conditions...

By wrapping a porous membrane around the coated stir bar, a novel membrane protected stir bar sorptive extraction (MPSBSE) was proposed to filter out the high molecular weight interferences (such as humic acid), resulting in the analysis of real environmental water samples without filtration or centrifugation. Hydrophilic and hydrophobic membranes were compared and hydrophobic polytetrafluoroethylene (PTFE) membrane impregnated with methanol was employed to protect the C18 coated stir bar. The impregnated methanol improves the transfer of target analytes from sample solution to the pores and lumen of the membrane, and then to the coated stir bar inside...

Stearic acid-based solid lipid nanoparticles (SLNs) were prepared using the microwave assisted one-pot microemulsions procedure pioneered by our group. In this study, non-steroidal anti-inflammatory drugs (NSAIDs) including indomethacin, ketoprofen and nimesulide were selected as ideal "test" drugs, based on their poor water solubility. The model drugs were incorporated within the SLNs by the microwave-assisted procedure at the time of SLN production. The microwave-produced drug-loaded SLNs were evaluated in terms of their physicochemical characteristics, drug release behavior and their uptake into against A549 cell line (human lung epithelial cells)...

Recent progress in endoscopic techniques has revealed that non-steroidal anti-inflammatory drugs (NSAIDs) often cause ulcers in the small intestine in humans, but effective therapy is not available at present. In the present study, we investigated the effects of feeding condition and the amount of dietary fiber (DF) in the diet on the formation of gastrointestinal ulcers induced by NSAIDs in dogs. Several types of diets containing various percentages of DF were given to dogs. Indomethacin (1 or 3 mg/kg, p.o...

The high-affinity IgE receptor (Fcε RI) is a heterotetramer of three subunits: Fcε RIα, Fcε RIβ, and Fcε RIγ (αβγ2) encoded by three genes designated as FCER1A, FCER1B (MS4A2), and FCER1G, respectively. Recent evidence points to FCERI gene variability as a relevant factor in the risk of developing allergic diseases. Because Fcε RI plays a key role in the events downstream of the triggering factors in immunological response, we hypothesized that FCERI gene variants might be related with the risk of, or with the clinical response to, selective (IgE mediated) non-steroidal anti-inflammatory (NSAID) hypersensitivity...

Lower back pain (LBP) remains an important problem due to its high prevalence. LBP is the fifth in frequency among reasons for seeking treatment, and one of the most common among the chronic pain syndromes. Nonsteroidal anti-inflammatory drugs (NSAIDs) are considered to be the «gold standard» in relieving back pain. In treatment of acute musculoskeletal pain syndromes, special attention is drawn to drugs characterized by high analgesic activity and a short half-life. Among the drugs in this group, dexketoprofen (a derivative of propionic acid), a water-soluble salt of the dextrorotatory enantiomer of ketoprofen, deserves special attention...

During the development of intranasal drug delivery systems for local/systemic effect or brain targeting, it is necessary to assess its cytotoxicity and drug transport through nasal epithelium. In order to avoid animal experiments or the use of excised tissues, in vitro cell models, such as RPMI 2650 cells, are being preferred during recent years. Nevertheless, the deposition of solid formulations into nasal cell layers with further transepithelial transport rate of drugs has been poorly studied or reported...

Inclusion of drugs in cyclodextrins (CDs) is a recognized tool for modifying several properties such as solubility, stability, bioavailability, and so on. The photoreactive behavior of the β-CD/ketoprofen (KP) complex upon UV exposure showed a significant increase in photodecarboxylation, whereas the secondary degradation products by hydroxylation of the benzophenone moiety were inhibited. The results may account for an improvement of KP photophysical properties upon inclusion, thus better fostering its topical use...

BACKGROUND: It is well known that radiation exposure to the heart and the use of non-steroidal anti-inflammatory drugs (NSAIDs) increase the risk of myocardial infarction (MI). Some NSAIDs are also known to act synergistically with ionizing radiation and have radio-sensitizing effects in radiotherapy. These evidences suggest that NSAIDs may affect the risk of MI after radiation exposure to the heart. In the present study, we investigated effects of NSAIDs on radiation-induced expression of cell adhesion molecules and COX-2, which are associated with inflammation and an increased risk of MI, in human endothelial cells...
