Diclofenac sodium and alginate was intercalated into montmorillonite to form uniform sized beads by gelation method. The structure and surface morphology of the synthesized composite beads were characterized by powdered X-ray diffraction, Fourier transform infrared spectroscopy, thermo gravimetric analysis and scanning electron microscopy. Diclofenac release kinetics of the composite in simulat...

This study demonstrates the effectiveness of a peptide shuttle in delivering diclofenac into and through human epidermis. Diclofenac was conjugated to a novel phenylalanyl-N-methyl-naphthalenylalanine-derived diketopiperazine (DKP) shuttle and to TAT (a classical cell penetrating peptide), and topically applied to human epidermis in vitro. DKP and TAT effectively permeated into and through huma...

Diclofenac is eliminated predominantly (approximately 50%) as its 4'-hydroxylated metabolite in humans, whereas the acyl glucuronide (AG) pathway appears more important in rats (approximately 50%) and dogs (>80-90%). However, previous studies of diclofenac oxidative metabolism in human liver microsomes (HLMs) have yielded pronounced underprediction of human in vivo clearance. We determined the ...

Pharmaceutical aviailability of diclofenac sodium from solid dispersions of PEG 6000 have been studied in comparison to those of the corresponding physical mixtures and pure diclofenac sodium. The diclofenac sodium is poorly water soluble drug. The properties of diclofenac sodium-PEG 6000 solid dispersions have been determined by the methods of differential scanning calorimetry (DSC), X-ray dif...

Diclofenac potassium is a widely used non-steroid anti-inflammatory drug which is absorbed more quickly than diclofenac sodium, Reported cases of rhabdomyolisis after only diclofenac are rare, we survey three cases in the literature. . We report a case of a 50 year-old man, chronic smoker and allergic to aspirin who developed a rhabdomyolysis associated with glossopharyngeal edema after oral ad...

In the era of knowledge economy, critical knowledge and technologies are key to enterprise competition. Huawei and ZTE are well known as top Chinese communication equipment suppliers. Both have paid great attention to intellectual property protection, and have applied a great amount of patents in information and communication technology. In this article, patent analysis is used to figure out wh...
