Ketoprofen edema

BACKGROUND: Zinc is known as an anti-inflammatory agent. Recent studies demonstrated the usage of zinc ions for enhancing the anti-inflammatory effect of Non-Steroidal Anti-inflammatory Drugs (NSAIDs). METHODS: This study compares the influence of chronic administration of zinc oxide nanoparticles (ZnO-NPs) and zinc oxide standard form (ZnO-S) on the anti-inflammatory and gastric activity of ketoprofen in rats. Both ZnO-S and ZnO-NPs were administered at doses of 7 or 14mg/kg (intraperitoneally (ip) and per os (po)) for 2 weeks followed by single po ketoprofen administration (in three doses: 5, 10, and 20mg/kg)...

Acquired lymphedema is a cancer sequela and a global health problem currently lacking pharmacologic therapy. We have previously demonstrated that ketoprofen, an anti-inflammatory agent with dual 5-lipoxygenase and cyclooxygenase inhibitory properties, effectively reverses histopathology in experimental lymphedema. We show that the therapeutic benefit of ketoprofen is specifically attributable to its inhibition of the 5-lipoxygenase metabolite leukotriene B4 (LTB4). LTB4 antagonism reversed edema, improved lymphatic function, and restored lymphatic architecture in the murine tail model of lymphedema...

We have designed a microemulsion (ME) containing Ketoprofen (KET) for anti-inflammatory effect evaluated using the rat paw edema model. The ME was prepared by adding propylene glycol (PG) loaded with 1% KET/water (3:1, w/w), to a mixture of sorbitan monooleate and polysorbate 80 (47.0%) at 3:1 (w/w) and canola oil (38.0%). The physicochemical characterization of KET-loaded ME involved particle size and zeta potential determination, entrapment efficiency, calorimetric analysis, and in vitro drug release. The in vivo anti-inflammatory study employed male Wistar rats...

Preclinical Research The aim of this study was to evaluate the efficacy of multiple applications of S(+)-flurbiprofen plaster (SFPP), a novel Nonsteroidal anti-inflammatory drug (NSAID) patch, for the alleviation of inflammatory pain and edema in rat adjuvant-induced arthritis (AIA) model as compared to other NSAID patches. The AIA model was induced by the injection of Mycobacterium butyricum and rats were treated with a patch (1.0 cm × 0.88 cm) containing each NSAID (SFP, ketoprofen, loxoprofen, diclofenac, felbinac, flurbiprofen, or indomethacin) applied to the paw for 6 h per day for 5 days...

We previously reported that dermal application using nanoparticles improves skin penetration. In this study, we prepared novel topical formulations containing ketoprofen (KET) solid nanoparticles (KETnano gel ointment) and investigated the antiinflammatory effect of the KET nanoparticle formulations on rheumatoid arthritis using adjuvant-induced arthritis (AA) rats. The KETnano gel ointment was prepared using a bead mill method and additives including methylcellulose and Carbopol 934; the mean particle size of the KET nanoparticles was 83 nm...

Bites by tarantulas (Theraphosidae, Mygalomorphae) in humans can result in mild clinical manifestations such as local pain, erythema, and edema. Vitalius dubius is a medium-sized, nonaggressive theraphosid found in southeastern Brazil. In this work, we investigated the mediators involved in the plasma extravasation caused by V. dubius venom in rats. The venom caused dose-dependent (0.1-100 μg/site) edema in rat dorsal skin. This edema was significantly inhibited by ((S)1-{2-[3(3-4-dichlorophenyl)-1-(3-iso-propoxyphenylacetyl)piperidine-3-yl]ethyl}-4-phenyl-1-azoniabicyclo[2...

A series of O-alkyl and O-acyl flavonoid derivatives was synthesized in high efficiency. Alkylation and acylation of 5-hydroxyflavonoids showed that the low reactivity hydroxyl group, 5-OH, well reacted with strong reagents whereas with weaker reagents, the different products were obtained dependently on structural characteristic of ring C of respective flavonoid. In order to evaluate anti-inflammatory activity, all compounds were tested for in vitro inhibition of bovine serum albumin denaturation and in vivo inhibition of carrageenan-induced mouse paw edema...

For the treatment of inflammatory-based diseases affected by circadian rhythms, the development of once-daily dosage forms is required to target early morning symptoms. In this study, Zn-alginate beads containing ketoprofen (K) were developed by a tandem technique prilling/ionotropic gelation. The effect of main critical variables on particles micromeritics, inner structure as well as on drug loading and in vitro drug release was studied. The in vivo anti-inflammatory efficacy was evaluated using a modified protocol of carrageenan-induced edema in rat paw administering beads to rats by oral gavage at 0, 3, or 5 h before edema induction...

Our previous study showed that the use of ricinoleic acid as an oil phase resulted in the formation of a stable pluronic lecithin organogel (PLO gel) with better thixotropic properties and higher permeation of ketoprofen than the isopropyl palmitate PLO gel. This study aims to evaluate and compare the in vitro and in vivo anti-inflammatory effects of the ricinoleic acid PLO gel system with isopropyl palmitate PLO gel. Ketoprofen was used as a model drug. In vitro anti-inflammatory activity and cell viability tests were performed in human rheumatoid arthritis synovial fibroblast cell line using a blank ricinoleic acid PLO gel and compared to that of the isopropyl palmitate PLO gel...

The anti-inflammatory activity of two extracts from the aerial parts of Ledum palustre has been reported. The volatile oil was obtained by supercritical fluid extraction (SFE) and the essential oil by hydrodistillation (HD). The oils were analysed by gas chromatography-mass spectrometry to monitor their composition. Both extracts shared as main compound (41.0-43.4%) ledol (23.3-26.7%) and ascaridole (15.1-4.5%). The anti-inflammatory activity was evaluated by the subcutaneous carrageenan injection-induced hind paw oedema...

Improving the gastrointestinal safety profile of nonsteroidal anti-inflammatory drugs (NSAIDs) is an important goal. Herein, we report two strategies, using the nonacidic propyphenazone structure, with potential to overcome the side effects of NSAIDs. Propyphenazone was employed to temporarily mask the free acid group of the widely used NSAIDs ibuprofen, diclofenac, and ketoprofen to develop three mutual prodrugs hypothesized to have minimal GI irritation. The three prodrugs exhibit in vivo anti-inflammatory and analgesic activities with improved potency over each parent drug when compared to a nonhydrolyzable control betahistine-propyphenazone (BET-MP)...

Crude saponin extracts of five medicinal plants used in the treatment of inflammatory diseases like rheumatoid arthritis, gout and haemorrhoids were screened for anti-inflammatory activity using carrageenan-induced rat paw oedema test. These plants were the whole plant of Schwenkia americana Linn (WSA), the rhizomes of Asparagus africanus Lam (RAA), the leaves of Dichrostachys cinerea Linn (LDC), the stem bark of Ficus iteophylla Miq (BFI) and the leaves of Indigofera pulchra Willd (LIP). A modify traditional method of crude saponins extraction was used to give the following percentage yields: WSA-2...

Pulmonary edema is a severe, potentially fatal clinical condition. It happens, when interstitial fluid is accumulating in the alveoli, impeding proper gas exchange. Typically we distinguish cardiogenic and noncardiogenic pulmonary edema. The article describes the case of severe pulmonary edema, which occurred in a young woman, free of cardiac diseases, about 30 hours after a suicidal drug poisoning (clozapine, ketoprofen, thiethylperazine). Both clozapine and ketoprofen intoxication, may be severe. Complications in these poisonings affect not only the central nervous system, but also the circulatory or respiratory system and may even occur several hours after the overdose of these drugs...

The purpose of this research was to investigate the potential of surface modified Poly (l-lactic acid) (PLA) microspheres as a carrier for site-specific delivery of anti-inflammatory drug, ketoprofen, for the treatment of rheumatoid arthritis. Microspheres were prepared by solvent evaporation method using 20% w/w PLA in methylene chloride and 100 mL of a 2.5% poly vinyl alcohol (PVA) solution. Formulations were optimized for several processing parameters like drug to polymer ratio, stirring rate and volume of preparation medium etc...

This study compared the efficacy and skin permeability of nine topical preparations of nonsteroidal anti-inflammatory drugs (NSAIDs) (ketoprofen, diclofenac, flurbiprofen, and piroxicam patches; and ketoprofen, diclofenac, piroxicam, niflumic acid, and ibuprofen gels) available in the European Union. The anti-inflammatory effect of these NSAID preparations was evaluated in rat models of acute inflammation (carrageenan or yeast treatment) and chronic inflammation (collagen or adjuvant treatment). Skin permeability of the preparations was evaluated in vitro using mouse skin...

BACKGROUND: To date, Kaposi sarcoma has not been mentioned among the adverse effects of triptolide/tripdiolide, ethyl acetate extracts or polyglycosides of the Chinese herbal remedy Tripterygium wilfordii Hook F. CASE REPORT: A patient was diagnosed with rheumatoid arthritis at the age of 29 years. She underwent treatment with corticosteroids, methotrexate and gold sodium thiosulfate, and was chronically taking ketoprofen. At the age of 59 years she started to take a powder (≈2 g/day) from a Chinese physician for treatment of rheumatoid arthritis...

Studies of methamphetamine (Meth)-induced neurotoxicity have traditionally focused on monoaminergic terminal damage while more recent studies have found that stress exacerbates these damaging effects of Meth. Similarities that exist between the mechanisms that cause monoaminergic terminal damage in response to stress and Meth and those capable of producing a disruption of the blood-brain barrier (BBB) suggest that the well-known high co-morbidity of stress and Meth could produce long-lasting structural and functional BBB disruption...
