Objective: The aim of the present study was to investigate anti-inflammatory activity of Diclocor in the setting of collagen-induced osteoarthritis in rats in comparison with its active monocomponents-diclofenac sodium and quercetin.
Methods: The study was conducted on the model of collagen-induced osteoarthritis and included measurement of sialic acids, glycoproteins, C-reactive protein, prostaglandin E2, 6-keto-prostaglandin F1α, thromboxane B2, and leukotriene B4. Lastly, morphologic study with morphometry was also performed.
Results: Diclocor is superior to quercetin and diclofenac sodium by the degree of pharmacological effect on some of the studied parameters. The differences between the values were statistically significant.
Conclusion: Diclocor is a promising corrector of inflammatory and destructive joint diseases. Owing to the presence of both diclofenac sodium and quercetin in its composition, Diclocor exhibits a complex mechanism of anti-inflammatory action affecting cyclooxygenase and lipoxygenase ways of arachidonic acid biotransformation.

Background/objectives: Films in the mouth offer a promising alternative drug delivery system for oral administration, with several advantages over traditional oral formulations. Furthermore, their non-invasive nature and easy administration make them conducive to increasing patient compliance. The use of active agents in these films can further improve their drug delivery properties, making them an even more useful drug delivery system.

Food supplements are used for a variety of purposes, one of which is weight reduction. As excess weight is a long-term condition, some supplements are expected to be used for long periods of time. The long-term use of these dietary supplements makes it highly likely that they will be combined with medications, increasing the risk of food supplement-drug interactions, which are not always known or disclosed, and can lead to serious health problems, as has been observed.

The presence of pharmaceuticals in nature systems poses a threat to the environment, plants, animals, and, last but not least, human health. Their transport in soils, waters, and sediments plays important roles in the toxicity and bioavailability of pharmaceuticals. The mobility of pharmaceuticals can be affected by their interactions with organic matter and other soil and water constituents.

Background: The aim of this study is to determine the impact of species and tissue differences on the glucuronidation of diclofenac in vitro.
Method: Microsomes from different species (rat, monkey, mouse, dog, and human) and rat and human tissues (liver, intestine, and kidney) were used to assess the rate of glucuronidation reaction of diclofenac. The metabolites were quantified using ultra high-performance liquid chromatography (UHPLC) and fitted into a Michaelis-Menten model to determine the metabolic kinetic parameters.

Nine manganese(II) complexes with a series of non-steroidal anti-inflammatory drugs (namely sodium diclofenac, diflunisal, flufenamic acid, sodium meclofenamate, mefenamic acid, and tolfenamic acid) were prepared in the presence of diverse nitrogen donors, i.e., pyridine, 1,10-phenanthroline, 2,2'-bipyridine and neocuproine, as co-ligands and were characterized with spectroscopic techniques and single-crystal X-ray crystallography.
