The aim of this study was to evaluate skin delivery of ketoprofen when covalently tethered to mildly cationic (2(+) or 4(+)) peptide dendrimers prepared wholly by solid phase peptide synthesis. The amino acids glycine, arginine and lysine formed the dendrimer with ketoprofen tethered either to the lysine side-arm (Nε) or periphery of dendrimeric branches. Passive diffusion, sonophoresis- and iontophoresis-assisted permeation of each peptide dendrimer-drug conjugate (D1-D4) was studied across mouse skin, both in vitro and in vivo...

Because the number of fish being used in research is increasing rapidly, evaluating the analgesic and pathologic effects of NSAIDin fish is essential. To determine the biochemical, histopathologic, physiologic and behavioral effects of 3 NSAID, 48 rainbow trout underwent anesthesia with tricaine methanesulfonate and exploratory celiotomy and were randomly assigned to receive flunixin(0.5 mg/kg IM), ketorolac (0.5 mg/kg IM), ketoprofen (2 mg/kg IM), or saline. Clinical pathologic variables were assessed 1 wk before surgery and 48 h after surgery...

An artificial microalgal-bacterial consortium was used to remediate a mixture of analgesics (ketoprofen, paracetamol and aspirin) in a stirred-tank photobioreactor. A hydraulic retention time (HRT) of 3days supported poor treatment because of the formation of p-aminophenol (paracetamol toxic metabolite). Increasing the HRT to 4days enhanced the bioremediation efficiency. After applying an acclimatization regime, 95% removal of the analgesics mixture, p-aminophenol and COD reduction were achieved. However, shortening the HRT again to 3days neither improved the COD reduction nor ketoprofen removal...

We investigated the role of the intracellular energy-sensing AMP-activated protein kinase (AMPK)/mammalian target of rapamycin (mTOR) pathway in the in vitro antiglioma effect of the cyclooxygenase (COX) inhibitor indomethacin. Indomethacin was more potent than COX inhibitors diclofenac, naproxen, and ketoprofen in reducing the viability of U251 human glioma cells. Antiglioma effect of the drug was associated with p21 increase and G2M cell cycle arrest, as well as with oxidative stress, mitochondrial depolarization, caspase activation, and the induction of apoptosis...

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...

The application of biopolymer aerogels as drug delivery systems (DDS) has gained increased interest during the last decade since these structures have large surface area and accessible pores allowing for high drug loadings. Being biocompatible, biodegradable and presenting low toxicity, polysaccharide-based aerogels are an attractive carrier to be applied in pharmaceutical industry. Moreover, some polysaccharides (e.g. alginate and chitosan) present mucoadhesive properties, an important feature for mucosal drug delivery...

The aquatic environment is under increased pressure by pharmaceutically active compounds (PhACs) due to anthropogenic activities. In spite of being found at very low concentrations (ng/L to μg/L) in the environment, PhACs represent a real danger to aquatic ecosystems due to their bioaccumulation and long-term effects. In this study, the presence in the aquatic environment of six non-steroidal anti-inflammatory drugs (ibuprofen, diclofenac, acetaminophen, naproxen, indomethacin, and ketoprofen), caffeine, and carbamazepine were monitored...

The use of acoustic cavitation for water and wastewater treatment (cleaning) is a well known procedure. Yet, the use of hydrodynamic cavitation as a sole technique or in combination with other techniques such as ultrasound has only recently been suggested and employed. In the first part of this paper a general overview of techniques that employ hydrodynamic cavitation for cleaning of water and wastewater is presented. In the second part of the paper the focus is on our own most recent work using hydrodynamic cavitation for removal of pharmaceuticals (clofibric acid, ibuprofen, ketoprofen, naproxen, diclofenac, carbamazepine), toxic cyanobacteria (Microcystis aeruginosa), green microalgae (Chlorella vulgaris), bacteria (Legionella pneumophila) and viruses (Rotavirus) from water and wastewater...

Environmental pollution by pharmaceuticals has become a major problem in many countries worldwide. However, little is known about the concentrations of pharmaceuticals in water sources in Japan. The objective of this study was to clarify variations in the concentrations of seven nonsteroidal anti-inflammatory drugs (NSAIDs) and in cyclooxygenase(COX)-inhibiting activities in river water and domestic wastewater collected from the Tone Canal and the Edo River Basin in Japan. Total NSAID concentrations were higher in the Tone Canal than in the Edo River, and the highest concentration was observed at the domestic wastewater inflow point located in the Tone Canal (concentration averages of salicylic acid, ibuprofen, felbinac, naproxen, mefenamic acid, diclofenac, and ketoprofen in wastewater samples were 55...
