A simple, specific, accurate, precise and reproducible method has been developed and validated for the simultaneous estimation of Thiocolchicoside and Diclofenac in pharmaceutical formulation by UV-Spectrophotometric method which includes Simultaneous Equation method (Method I), Absorbance Correction method (Method II). For development of Method I, wavelengths were selected 260.0 nm λmax for th...

The metabolism of diclofenac has been reported to produce reactive benzoquinone imine intermediates. We describe the identification of mercapturic acid derivatives of diclofenac in rats and humans. Three male Sprague-Dawley rats were administered diclofenac in aqueous solution (pH 7) at 50 mg/kg by intraperitoneal injection, and urine was collected for 24 h. Human urine specimens were obtained,...

The aim of this study was to investigate effects of subchronic exposure to sublethal levels of diclofenac on growth, oxidative stress, and histopathological changes in Danio rerio. The juvenile growth tests were performed on Danio rerio according to OECD method number 215. Fish at the age of 20 days were exposed to the diclofenac environmental concentration commonly detected in the Czech rivers...

Diclofenac is a widely used drug that can cause serious hepatotoxicity, which has been linked to metabolism by cytochrome P450s (P450). To investigate the role of oxidative metabolites in diclofenac toxicity, a model for P450-related toxicity was set up in Saccharomyces cerevisiae. We expressed a drug-metabolizing mutant of cytochrome P450 BM3 (BM3 M11) in yeast. Importantly, BM3 M11 yielded si...

Purpose. In order to improve the drug availability after intravitreal administration, solid lipid nanoparticles (SLNs) containing diclofenac were prepared. Methods. In this experimental study, 18 albino rabbits were included. In right and left eyes of all rabbits, SLNs containing diclofenac and commercial form of diclofenac (0.3 mg drug) were intravitreally injected, respectively. One, four, tw...

BACKGROUND Tonsillectomy is a common pediatric surgical procedure resulting in significant postoperative pain. There is ongoing controversy as to the most satisfactory analgesic regimen. Nonsteroidal antiinflammatory drugs (NSAIDs) are an alternative to opioids in this setting. NSAID use in tonsillectomy has been shown to be opioid sparing in the recovery period and to have similar analgesic ef...

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 disti...

BACKGROUND Succinylcholine-induced myalgia is a minor but frequent complication. Its incidence and severity is different according to the studied population. The aim of this study was evaluation of the diclofenac patch effect on postoperative succinylcholine-related myalgia in cesarean section. METHODS The study was a prospective randomized double blind, placebo-controlled trial. One hundred ...

BACKGROUND AND AIMS Acute pancreatitis following endoscopic retrograde cholangiography presents a unique opportunity for prophylaxis and early modification of the disease process because the initial triggering event is temporally well defined and takes place in the hospital. We report a prospective, single-center, randomized, double-blind controlled trial to determine if rectal diclofenac reduc...

Various aqueous and oily diclofenac ophthalmic formulations were subjected to accelerated and long term stability studies. Degradation of diclofenac was found to follow first-order kinetics. Among the aqueous formulations containing preservative, formulation with PMA, PMN, SA, MP/PP and SMS showed diclofenac content above 90% after 6 months of accelerated and 12 months of room temperature stora...
