The major-histocompatibility-complex-(MHC)-class-I-related molecule MR1 can present activating and non-activating vitamin-B-based ligands to mucosal-associated invariant T cells (MAIT cells). Whether MR1 binds other ligands is unknown. Here we identified a range of small organic molecules, drugs, drug metabolites and drug-like molecules, including salicylates and diclofenac, as MR1-binding ligands. Some of these ligands inhibited MAIT cells ex vivo and in vivo, while others, including diclofenac metabolites, were agonists. Crystal structures of a T cell antigen receptor (TCR) from a MAIT cell in complex with MR1 bound to the non-stimulatory and stimulatory compounds showed distinct ligand orientations and contacts within MR1, which highlighted the versatility of the MR1 binding pocket. The findings demonstrated that MR1 was able to capture chemically diverse structures, spanning mono- and bicyclic compounds, that either inhibited or activated MAIT cells. This indicated that drugs and drug-like molecules can modulate MAIT cell function in mammals.

A molecularly imprinted polymer (MIP) was synthesized by precipitation polymerization using diclofenac (DFC) as a template. Binding characteristics of the MIP were evaluated using equilibrium binding experiments. Compared to the non-imprinted polymer (NIP), the MIP showed an outstanding affinity towards DFC in an aqueous solution with a binding site capacity (Q(max)) of 324.8 mg/g and a dissociation constant (K(d)) of 3.99 mg/L. The feasibility of removing DFC from natural water by the MIP was demonstrated by using river water spiked with DFC. Effects of pH and humic acid on the selectivity and adsorption capacity of MIP were evaluated in detail. MIP had better selectivity and higher adsorption efficiency for DFC as compared to that of powdered activated carbon (PAC). In addition, MIP reusability was demonstrated for at least 12 repeated cycles without significant loss in performance, which is a definite advantage over single-use activated carbon.

Diclofenac (a non-steroidal anti-inflammatory drug) and pethidine (a synthetic opiate) are the two analgesics most commonly used to relieve the pain of ureteric colic. Fast frame renography is a non-invasive means of imaging ureteric peristalsis and renal drainage. The aim of this study was to determine the effects of each of these drugs on the drainage pattern of the upper tracts. Twelve normal male volunteers were studied. All underwent a standard fast frame renogram using 75 MBq of technetium-99m-mercaptoacetyltriglycine, and were then administered either 100 mg pethidine or 75 mg diclofenac by intramuscular injection. Fast frame renography was then repeated. Peristalsis was determined from the condensed image of each ureter and the renogram curves were analysed to obtain standard parameters and deconvolution analysis. Diclofenac caused a profound disruption to both ureteric peristalsis and the renogram curve. This effect was not seen after the administration of pethidine. Deconvolution analysis suggests the effects of diclofenac are mediated via a direct effect on drainage rather than by any alteration of blood flow to the kidney. This study suggests that pethidine is the analgesic of choice prior to renography and that inferences about alterations of drainage in the presence of diclofenac should be interpreted with care.

Diclofenac is used for the treatment of osteoarthritis (OA); however, like other nonsteroidal anti-inflammatory drugs (NSAIDs) it can be associated with serious dose-related adverse events (AEs). Low-dose SoluMatrix® diclofenac has been developed to provide efficacy at lower diclofenac doses. A recently published Phase III study evaluated the efficacy and safety of SoluMatrix diclofenac 35 mg twice daily (b.i.d.) and thrice daily (t.i.d.) in patients with OA pain treated for 12 weeks.

A 34 year old female developed acute pancreatitis after commencing diclofenac for a painful arthropathy. The possible role of prostaglandin inhibition in non-steroidal analgesic drug-induced pancreatitis is discussed and the suggestion is made that serum amylase should be measured in patients who develop abdominal pain, following ingestion of non-steroidal anti-inflammatory
Lumiracoxib was well absorbed and demonstrated similar potency to naproxen as a COX-2 inhibitor (77% and 66% inhibition, respectively, vs. placebo), but it differed in being more selective (24% and 97% inhibition of thromboxane B(2) vs. placebo). Gastric PGE(2) was reduced by 69% by naproxen (P < 0.001 vs. placebo) and 29% by lumiracoxib (P < 0.01 vs. placebo and naproxen). No subjects developed gastroduodenal erosions on lumiracoxib (vs. 75% on naproxen and 12.5% on placebo). (51)Cr-EDTA absorption increased significantly with naproxen but not lumiracoxib.

Because of these physiological effects and the widespread use of the selective COX-2 inhibitor, celecoxib, we wanted to determine if inhibition of COX-2 would affect incisional skin wound healing.
Topical diclofenac in 2.5% hyaluronan inhibits basal cell carcinoma, actinic keratosis, and murine colon-26 growth in vivo. colon-26 tumor growth was preceded by angiogenesis and reduced apoptotic and mitotic indices. Diclofenac reduced proliferation and viability in vitro, and stimulated apoptosis. Hyaluronan inhibited proliferation and viability at 1 mg/ml but was inactive below this level. Topical application of diclofenac inhibited tumor prostaglandin synthesis and retarded angiogenesis and tumor growth (ratio of treatment:control, 0.174). The mitotic index remained unaltered in vivo, whereas the apoptotic index and necrosis were increased. Topical vehicle exhibited slight antitumor and antiangiogenesis activity. The substantial quantities of diclofenac delivered locally in hyaluronan may exhibit antitumor activity in similar fashion to those seen in vitro and explain its clinical efficacy.

Of the 1387 patients included, 915 were on Celecoxib. In the NSAID group, 204 had used multiple NSAIDs in sequence. Of the Celecoxib users, 164 had switched over to an NSAID during the study period. New onset of hypertension was significantly higher in the Celecoxib users as compared to non-selective NSAID users (3.06% vs. 1.27%, P = 0.04). However, those who had switched over to NSAIDs did not show this trend. NSAID users, on the other hand, had significant gastrointestinal (GI) toxicity (2.54% vs. 0.327%, P = 0.001). A significant number of Celecoxib users who switched over to NSAIDs also developed GI toxicity (6.1% vs. 1.21%, P = 0.018) over a shorter time span, as compared to the continuous NSAID users. Multiple NSAID users had higher adverse events (6.37% vs. 2.23%, P = 0.023) as compared to single NSAID users.
Study results strongly suggest the pre-emptive analgesic efficacy of a single oral dose of Lamotrigine over Diclofenac and Topiramate in postoperative pain control.

We report a case of severe metabolic acidosis associated with acute renal failure and septicaemia following treatment with maximal therapeutic doses of metformin and diclofenac. On the second day of intensive care the patient deteriorated with respiratory insufficiency and abdominal pain during continuous renal replacement therapy. A laparoscopy revealed a perforated cholecystitis with abscess formation. The patient regained renal function and recovered. Intake of diclofenac 5 days before this episode could have been the main cause of renal insufficiency and metabolic acidosis in this patient and could also have delayed surgical treatment by masking early clinical signs of perforated cholecystitis. The renal failure may also have caused metformin and lactate to accumulate, contributing to the mixed pattern of metabolic acidosis. This case report describes a mixed organic and non-organic metabolic acidosis associated with acute renal failure, presumably resulting from a combination of drugs and diseases often found in the elderly - metformin for diabetes mellitus and a non-steroidal anti-inflammatory drug for cholecystolithiasis. Acid-base balance and electrolyte changes were rapidly normalized by continuous renal replacement therapy.

A simple solid phase microextraction method based on molecularly imprinted polymer sorbent in the hollow fiber (MIP-HF-SPME) combined with fiber optic-linear array spectrophotometer has been applied for the extraction and determination of diclofenac in environmental and biological samples. The effects of different parameters such as pH, times of extraction, type and volume of the organic solvent, stirring rate and donor phase volume on the extraction efficiency of the diclofenac were investigated and optimized. Under the optimal conditions, the calibration graph was linear (r(2)=0.998) in the range of 3.0-85.0 μg L(-1) with a detection limit of 0.7 μg L(-1) for preconcentration of 25.0 mL of the sample and the relative standard deviation (n=6) less than 5%. This method was applied successfully for the extraction and determination of diclofenac in different matrices (water, urine and plasma) and accuracy was examined through the recovery experiments.

This study investigates the relationship between exposure to non-steroidal anti-inflammatory drugs (NSAIDs) and liver injuries using the French Pharmacovigilance Database. We use the case/non-case methodology, where 'cases' were reports of the reactions of interest (liver injuries as recorded in the database according to the WHO-ART classification including cytolytic and cholestatic hepatitis, acute hepatitis, liver enzyme elevations). 'Non-cases' were all reports of reactions other than these being studied. Amineptine and acetaminophen were used as 'positive controls'. Among the 42,913 adverse drug reactions recorded in the database between January 1995 and December 1997, 5708 (13 per cent) were liver injuries. In comparison with other drugs in the database, liver injuries were inversely associated with exposure to NSAIDs, whatever the class of the drugs (OR 0.3 [0.3-0.4]). In contrast, liver injuries were significantly related to acetaminophen (OR 2.1 [1.9-2.3]), and amineptine (OR 14.0 [10.5-18.7]). Naproxen and diclofenac were associated with a higher frequency of liver injuries, respectively 15.7 per cent and 11.5 per cent. The risk associated with NSAIDs alone significantly decreased when the analysis was performed after exclusion of hepatotoxic drugs associated with NSAIDs (except for naproxen). The present results show the low frequency of liver damage associated with NSAIDs. The main factor appears to be concomitant exposure to other hepatotoxic drugs.

Mean (± standard deviation) Tmax for nano-formulated diclofenac 18 (0.62 ± 0.35 h) and 35 mg (0.59 ± 0.20 h) demonstrated faster absorption than diclofenac 50 mg (0.80 ± 0.50 h). The T1/2 was similar between nano-formulated diclofenac 35 mg and diclofenac 50 mg (1.85 ± 0.45 h vs 1.92 ± 0.38 h, respectively). The Cmax for nano-formulated diclofenac 35 mg and diclofenac 50 mg was comparable in fasted subjects (1347 ± 764 ng/mL vs 1316 ± 577 ng/mL, respectively), but lower in fed subjects (524 ± 222 ng/mL vs 951 ± 391 ng/mL, respectively). As anticipated, there was a 19% reduction in drug exposure (AUC0(-∞)) when subjects received nano-formulated diclofenac 35 mg compared with diclofenac 50 mg under fasting conditions (1225 ± 322 h*ng/mL vs 1511 ± 389 h*ng/mL, respectively). Safety and tolerability were comparable between nano-formulated diclofenac and diclofenac.
Lyophilized drug manufacturing and intra-articular (IA) applications have increased to address gastrointestinal side effects resulting from chronic treatment with non-steroidal anti-inflammatory drugs (NSAIDs) for degenerative joint disease. Accordingly, we histologically examined joint and stomach tissues from rats to determine and compare the effects of long-term treatment with an IA corticosteroid (methylprednisolone acetate), lyophilized NSAID (tenoxicam), and non-lyophilized NSAID (diclofenac) following application to the knee joint.

The popular over-the counter analgesic drug diclofenac has recently been associated with increased rates of myocardial infarction among patients with cardiovascular risk as well as among healthy populations. Although other traditional non-steroidal anti-inflammatory drugs (tNSAID) have also been accused to exert this risk, literature data at present gives reason to believe that the hazard of myocardial infarction is mainly associated with diclofenac. Large retrospective analyses of clinical data have repeatedly shown that diclofenac, similar as some selective COX-2 inhibitors, increases the propensity to experience adverse cardiovascular and atherothrombotic events. These associations cannot be explained with the deteriorating effect of NSAID on arterial hypertension, as the statistical associations only have been found conclusively for diclofenac and not for other tNSAID. The reasons for this novel side-effect of diclofenac may be based on the specific pharmacology of diclofenac, which, similar to selective COX-2 inhibitors, alters vascular levels of platelet active prostaglandins in a way that favours arterial thrombosis. In this review, we summarize the clinical evidence about adverse atherothrombotic events associated with diclofenac and dissect the pharmacological reasons beyond this phenomenon in comparison to other tNSAID.

The inhibiting effects of both substances were not only mediated by absolute parameters (e.g. breaking load, BV), but we have shown, for the first time, that additional changes occurred in the microstructural bony network. Especially in patients at risk for delayed bone healing (arteriosclerosis, diabetes mellitus, smoking), the administration of these drugs should be weighed carefully.
We studied the functional role of angiotensin II (AII) receptor subtypes and vasodilatory endothelial autacoid release in response to AII in isolated perfused rabbit hearts. AII infusion induced biphasic changes in coronary perfusion pressure (CPP): an initial increase was followed by a decrease until a plateau was reached. At higher concentrations of AII (> or = 10 nmol/l) this plateau phase was lower than the initial CPP level. AII infusion elicited inverse changes in peak left ventricular pressure (LVP): coronary constriction was associated with a transient decline, and during the plateau phase LVP was clearly increased. AII also moderately augmented prostacyclin (PGI2) release from the coronary vascular bed. The AII-induced changes in CPP, LVP, and PGI2 release were effectively inhibited by the AT1 receptor subtype antagonist ICI D8731 (30 nmol/l), but not by the AT2 receptor antagonist CGP 42112 (30 nmol/l). The adenosine A1 receptor antagonist 8-phenyltheophylline (0.1 mumol/l) attenuated the decline in CPP following the constriction phase without affecting the changes in LVP during AII infusion. The cyclooxygenase inhibitor diclofenac (1 mmol/l) had no effect on the AII-induced changes in CPP, whereas the nitric oxide-synthase inhibitor NG-nitro-L-arginine (30 mumol/l) markedly potentiated the vasoconstriction but was without effect on the plateau phase of the response. In contrast to AII, the thromboxane analogue U46619 elicited sustained increases in CPP which were associated with slight decreases in LVP.(ABSTRACT TRUNCATED AT 250 WORDS)
The film forming and coating properties of Glycerol ester of maleic rosin (GMR) and Pentaerythritol ester of maleic rosin (PMR) were investigated. The 2 rosin-based biomaterials were initially characterized in terms of their physicochemical properties, molecular weight (Mw), and glass transition temperature (Tg). Films were produced by solvent evaporation technique on a mercury substrate. Dibutyl sebacate plasticized and nonplasticized films were characterized by mechanical (tensile zzzz strength, percentage elongation, and Young's modulus), water vapor transmission (WVT), and moisture absorption parameters. Plasticization was found to increase film elongation and decrease the Young's modulus, making the films more flexible and thereby reducing the brittleness. Poor rates of WVT and percentage moisture absorption were demonstrated by various film formulations. Diclofenac sodium-layered pellets coated with GMR and PMR film formulations showed sustained drug release for up to 10 hours. The release rate was influenced by the extent of plasticization and coating level. The results obtained in the study demonstrate the utility of novel rosin-based biomaterials for pharmaceutical coating and sustained-release drug delivery systems.

There are many categories and individual types of headache and most have a variety of treatment protocols, while a few are best treated by just one medication. This paper will concentrate on acute care medications for migraine and discuss some new and future acute care treatments. There is not much to discuss about prevention, except that onabotulinumtoxinA has been approved for prevention of chronic migraine. Cluster headache will also be discussed, as there are some future treatments for acute care and prevention being studied at present. For the acute care of migraine in the US, we have seven triptans by tablet plus other routes and one non steroidal anti-inflammatory medication approved by the FDA that is currently available (Cambia brand of buffered diclofenac potassium for oral solution). There are several other acute care medications in various stages of development and there are three new methods of administering a triptan and others under investigation. The optimal acute care therapy for migraine should be faster, easier to use and more efficient with fewer adverse events than what is currently available. What follows is a brief review of the status in development for five of the many new acute care medications being investigated: the CGRP antagonist tablet telcagepant, the sumatriptan iontophoretic patch Zelrix, sumatriptan powder for use in the OptiNose apparatus, dihydroergotamine for oral inhalation (Levadex), civamide nasal solution for prevention of episodic cluster headache (Civanex) and sphenopalatine ganglion stimulation for acute cluster attacks in chronic cluster headaches. Other future treatments that will not be discussed include transcranial magnetic stimulation, a 5-HT(1F) agonist named alniditan, large conductance calcium-activated potassium channel openers, glial modulators or other medications and devices in early stages of development.

We performed a retrospective analysis of the records of 16 patients diagnosed in our dermatology service as Sweet's syndrome (SS), with the aim of describing their clinical findings and associations, and comparing our results with previous ones. The mean age was 51, and 82% were female. A previous infection was recorded in 5 cases (31%) (gastroenteritis, primary pulmonary tuberculosis, upper airways infection, wound infection, and streptococcal pharyngitis). Two patients (12%) suffered from a malignant neoplasia (acute myeloid leukemia and prostatic neoplasia), another patient had a coincident bout of acute ulcerative colitis with pyoderma gangrenosum, and a third one referred previous ingestion of diclofenac and intense sun exposure. Most patients had their lesions localized on the upper extremities (75%), fever was present in 8 cases (50%), arthralgia in six (37%), and erythema nodosum in five (31%). The most frequent laboratory finding was an elevated sedimentation rate (93% had values over 20 mm/h), and only 44% of patients had leukocyte counts over 10 x 10(9)/l. Urinanalysis was abnormal in one third of the patients, and chest roentgenograms, performed in ten patients, were all normal. Most of the patients were treated with low doses of oral prednisone (30 mg/day) with good results. The disease recurred in 25% of the patients.
