Nanocapsules (NCs) are submicron-sized core shell systems which present important advantages such as improvement of drug efficacy and bioavailability, prevention of drug degradation, and provision of controlled-release delivery. The available methods for NC production require expensive recovery and purification steps which compromised the morphology of nanocapsules. Industrial applications of NCs have been avoided due to the aforementioned issues. In this study, we developed a new method based on a modified self automicroemulsifying drug delivery system (SMEDDS) for in situ NCs production within the gastrointestinal tract...

In this work, the presence of selected emerging contaminants has been investigated in two reservoirs, La Fe (LF) and Rio Grande (RG), which supply water to two drinking water treatment plants (DWTPs) of Medellin, one of the most populated cities of Colombia. An analytical method based on solid-phase extraction (SPE) of the sample followed by measurement by liquid chromatography coupled to tandem mass spectrometry (LC-MS/MS) was developed and validated for this purpose. Five monitoring campaigns were performed in each reservoir, collecting samples from 7 sites (LF) and 10 sites (RG) at 3 different depths of the water column...

The increasing worldwide consumption of pharmaceuticals and personal care products such as ibuprofen (IBU) is leading to the widespread and persistent occurrence of these chemicals and their transformation products in soils and waters. Although at low concentrations, the continuous discharge of these micropollutants and the incomplete removal by the actual wastewater treatments can provoke accumulation in the environment with risks for the trophic chain. Non-target organisms as duckweed can be used for the environmental monitoring of pharmaceutical emerging contaminants...

Thirty million people worldwide consume each day nonsteroidal anti-inflammatory drugs (NSAIDs), a heterogeneous group of pharmaceuticals used for its analgesic, antipyretic, and anti-inflammatory properties. Recent studies report high NSAID concentrations in wastewater treatment plant effluents, in surface, ground, and drinking water, and in sediments. NSAIDs are also known to induce toxicity on aquatic organisms. However, toxicity in natural ecosystems is not usually the result of exposure to a single substance but to a mixture of toxic agents, yet only a few studies have evaluated the toxicity of mixtures...

Clopidogrel (Plavix(®), Sanofi-Aventis), the adenosine diphosphate P2Y12 receptor antagonist, is reported to be effective in the prevention of cardiovascular events and is often used in combination with aspirin, particularly in high-risk patients. ASP6537 is a reversible cyclooxygenase (COX)-1 inhibitor that is under investigation as an anti-platelet agent. First, we investigated the reversibility of the antiplatelet effect of ASP6537 and its interaction with ibuprofen to compare the usability of ASP6537 with that of aspirin...

Fever or Pyrexia means abnormal rise in body temperature above the usual range of normal in response to a variety of infectious, immunological and neoplastic stimuli. To normalize these febrile conditions, several synthetic agents are in clinical practice such as acetaminophen, ibuprofen, and aspirin. However, they are having many side effects which sometimes challenge their applications. The various sources are under investigation worldwide to overcome issues of unwanted effects and to better therapeutic response...

Although single-drug therapy may prove insufficient in treating bacterial infections or inflammation after orthopaedic surgeries, complex therapy (using both an antibiotic and an anti-inflammatory drug) is thought to address the problem. Among drug delivery systems (DDSs) with prolonged drug release profiles, nanoporous anodic titanium dioxide (ATO) layers on Ti foil are very promising. In the discussed research, ATO samples were synthesized via a three-step anodization process in an ethylene glycol-based electrolyte with fluoride ions...

: Using a nonsteroidal anti-inflammatory drug (NSAID) before a single bout of mechanical loading can reduce bone formation response. It is unknown whether this translates to an attenuation of bone strength and structural adaptations to exercise training. PURPOSE: To determine whether NSAID use before exercise prevents increases in bone structure and strength in response to weight-bearing exercise. METHODS: Adult female Wistar rats (n=43) were randomized to Ibuprofen (IBU) or Vehicle (VEH) and Exercise (EX) or Sedentary (SED) groups in a 2x2 (drug, activity) ANCOVA design with body weight as the covariate, and data are reported as mean±SE...

OBJECTIVE: Double checking medications at initial assessment within paediatric emergency departments (EDs) has the potential to delay patient flow, and doubt has been cast on the efficacy of double checking in all but high-risk medications. We aimed to benchmark current practice for the use of Patient Group Direction (PGD) medications at initial assessment in EDs within the Paediatric Emergency Research UK and Ireland (PERUKI) network, with a focus on the use of 'single-checker' PGDs...

Non-specific protein adsorption on hydrophobic solid phase extraction (SPE) adsorbents can reduce the efficacy of purification. To improve sample clean-up, poly(divinyl benzene) (PDVB) monoliths grafted with hydrophilic polyethylene glycol methacrylate (PEGMA) were developed. Residual vinyl groups (RVGs) of the PDVB were employed as anchor points for PEGMA grafting. Two PEGMA monomers, M n 360 and 950, were compared for graft solutions containing 5-20% monomer. Protein binding was qualitatively screened using fluorescently labeled human serum albumin (HSA) to determine optimal PEGMA concentration...

Prediction of gastrointestinal absorption of thirteen newly synthesized β-hydroxy-β-arylalkanoic acids (HAA) and ibuprofen was performed using PAMPA test. The highest values of PAMPA parameters (%T and Papp) were calculated for 1C, 1B and 2C and these parameters were significantly lower in comparison to ibuprofen. QSPR analysis was performed in order to identify molecular descriptors with the highest influence on %T and -logPapp and to create models which could be used for the design of novel HAA with improved gastrointestinal absorption...

We report the synthesis of a series of 6- and 7-substituted coumarins with commercially available NSAIDs (13a-h and 14a-h) as potential tools for the treatment of RA and related diseases. All compounds resulted effective in inhibiting the RA over-expressed hCA IV with KIs comprised between 0.44-9.8 nM. Among the other RA relevant hCA isoforms (i.e. IX and XII), compounds 13f and 14a,b resulted commonly effective in inhibiting their activity. The antihyperalgesic activity of such compounds was assessed by means of the Paw-pressure and Incapacitance tests using an in vivo RA model induced by CFA...

BACKGROUND: Effective postoperative pain management is essential for the rehabilitation of the surgical patient. No 'gold standard' exists after total hip arthroplasty (THA) and combinations of different nonopioid medications are used with virtually no evidence for additional analgesic efficacy compared to monotherapy. The objective of this trial is to investigate the analgesic effects and safety of paracetamol and ibuprofen alone and in combination in different dosages after THA. METHODS: PANSAID is a placebo-controlled, parallel four-group, multicentre trial with centralised computer-generated allocation sequence and allocation concealment and with varying block size and stratification by site...

We report a new prodrug micelle-based approach in which a model hydrophobic non-steroidal anti-inflammatory drug (NSAID), ibuprofen (Ibu), is tethered to amphiphilic methoxy polyethylene glycol-polypropylene fumarate (mPEG-PPF) diblock copolymer via hydrolytic anhydride linkages for potential controlled release applications of NSAIDs. Synthesized mPEG-PPF-Ibu polymer drug conjugates (PDCs) demonstrated high drug conjugation efficiency (∼90%) and self-assembled to form micellar nanostructures in aqueous medium with critical micelle concentrations ranging between 16 and 30μg/mL...

Muthanna J Ahmed
Pharmaceutical pollutants are of significant effect on the environment, so that their treatments have been addressed in many studies. Activated carbon (AC) adsorbent shows best attraction for these compounds due to its unique characteristics represented by high capacity and porosity. In this article, the adsorption performance of AC towards non-steroidal anti-inflammatory drugs (NSAIDs) such as ibuprofen, ketoprofen, naproxen, and diclofenac were reviewed. According to collected data, maximum adsorption capacities of 417, 25, 290, and 372 mg/g were obtained from Langmuir isotherm for these drugs, respectively...

PURPOSE: Nonsteroidal anti-inflammatory drugs (NSAIDs) are commonly used to treat pain, inflammation, and fever in the USA. Unfortunately, NSAIDs have been associated with an increased risk of adverse cardiovascular events, especially among NSAID users with established cardiovascular disease (CVD). In 2005, the Food and Drug Administration (FDA) released an initial warning regarding NSAID use and CVD risk, and recently, in July 2015, released an updated statement strengthening this initial warning...
