conclusions diclofenac-loaded nanoparticles based on properties of chitosan gelation could delay the release of drugs in the stomach and be further evaluated for the enteric delivery of diclofenac. objectives the aim of this study was to prepare and evaluate diclofenac-loaded chitosan nanoparticles based on the ionotropic gelation method. materials and methods chitosan (cs) nanoparticles contai...

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...

PURPOSE To investigate the inhibitory effect of diclofenac sodium on rabbit corneal epithelial cells (RCECs) in vitro and explore its pharmacological mechanism. METHODS The fresh rabbit cornea was cultured to obtain the primary RCECs, and RCECs of passage 2 were used in this research. The cells were divided into experimental groups, the cells in which were incubated with different concentrati...

Diclofenac sodium or Sodium-2-[(2, 6-dichlorophenyl) amino] phenyl] acetate, is widely used as non-steroidal antiinflammatory agent in therapeutics, it inhibits the cyclooxygenase enzyme1. Various spectrophotometric2-11, chromatographic12-18, colorimetric19-20 and flourimetric21-23 methods have been developed for quantification of diclofenac sodium. Extensive literature survey revealed that a v...

Diclofenac sodium and diclofenac potassium in tablet dosage form were tested for their bioavailability and disposition kinetics in a group of 18 rabbits in normal and Escherichia coli induced febrile condition with a washout period of 7 days. Biochemical and physiological parameters were measured in both normal and febrile state. Diclofenac levels in plasma were determined using a reversed-phas...

The aim of this study was to improve the transdermal permeation of Diclofenac Soduim. Permeation studies were carried out in -vitro using Cellophane Membrane. Topical gel formulations of diclofenac sodium were prepared by using Carbopol 934, Carbopol 940, sodium carboxymethylcellulose (NaCMC), polymer as a gel-forming material that is biocompatible and biodegradable. The skin permeation enhance...

this study investigates the effectiveness of the antinociceptive effects of diclofenac, an nsaid, on the nociceptive behavior of morphine-treated rats on formalin test.rats were treated with morphine-containing drinking water for twenty one days, which induced morphine dependence. the antinociceptive effects of 8, 16, and 32 mg/kg doses of diclofenac were then evaluated and compared with distil...

Class of Nonsteroidal Anti-Inflammatory Drugs (NSAIDs), includes Anaprox (naproxen), Ansaid (flurbiprofen), Arthrotec (diclofenac sodium/misoprostil), Caldolor (ibuprofen), Cambia (diclofenac potassium), Cataflam (diclofenac), Celebrex (celecoxib), Daypro (oxaprozin), Daypro Alta (oxaprozin), Duexis (ibuprofen and famotidine), Dyloject (diclofenac), Feldene (piroxicam), Flector (diclofenac), In...

Diclofenac is a nonsteroidal anti-inflammatory drug (NSAID). A efficient, simple and least time consuming spectrophotometric method for the assay of diclofenac sodium has been developed. Comparison of assay of four different brands of diclofenac sodium (Dicloran, Defnac, Artifin, voltral) has also been done available in public medical store of Karachi, Pakistan. The assay is based on the ultrav...
