BACKGROUND The goal of this study was to determine the effects of a selective Cyclooxygenase (COX)-2 inhibitor on the inhibition of tumor growth and pulmonary metastasis in a Lewis Lung Carcinoma (LLC) animal model. METHODS For immunoblot analysis of COX-2 and PGE2, cells were treated with irradiation in the presence or absence of celecoxib. The right thighs of male, 6-week old C57/BL mice we...
PURPOSE To determine whether celecoxib inhibits VEGF secretion from ARPE-19 cells and to investigate further the safety and effectiveness of periocular celecoxib-poly (lactide-co-glycolide; PLGA) microparticles in inhibiting elevations in retinal PGE(2), VEGF, and blood-tissue barrier leakage at the end of 60 days in a streptozotocin diabetic rat model. METHODS VEGF mRNA and protein expressio...
this study was designed to examine the antidepressant effect of celecoxib (200 mg/day) augmentation of sertraline in the treatment of female patients with first episode of major depression over 8 weeks of therapy.thirty female outpatients diagnosed with first episode of major depression, were recruited for this study. participants were randomly assigned into two equal groups receiving either se...
objective(s): noise-induced hearing loss (nihl) is the major cause of acquired hearing loss. celecoxib, a cyclooxygenase-2 (cox-2) inhibitor, is a non- steroidal anti- inflammatory drug (nsaid) with known antioxidant and antineoplastic activity. therefore, we monitored the extent of temporary noise- induced threshold shifts (tts) and cochlear damage caused by high level 4- khz noise exposure t...
Dimethyl-celecoxib is a celecoxib analog that lacks the capacity as cyclo-oxygenase-2 inhibitor and therefore the life-threatening effects but retains the antineoplastic properties. The action mechanism at the molecular level is unclear. Our in vitro assays using a sarcoplasmic reticulum preparation from rabbit skeletal muscle demonstrate that dimethyl-celecoxib inhibits Ca2+-ATPase activity an...
Effects of a high-selenium yeast supplement on celecoxib plasma levels: a randomized phase II trial.
A combination of celecoxib and selenium was used in a randomized double-blind Phase II trial as a preliminary study to a multicenter Phase III colorectal cancer chemoprevention trial using these two agents together. The purpose of this trial was to determine whether high-selenium baker's yeast [(Saccharomyces cerevisiae) 200 microg once daily] in combination with celecoxib (400 mg once daily) a...
Celecoxib, a nonsteroidal anti-inflammatory drug, has been reported to have antitumor and antimetastatic activities, it potential for application in cancer treatments. The expression of matrix metalloproteinase (MMP)-2/9 is strongly correlated with malignancy, inhibition these MMPs believed be effective improving the effects drugs. We previously revealed that UTX-121, which converted sulfonamid...
We assessed the effectiveness of celecoxib in the prevention of heterotopic ossification (HO) following primary total hip replacement (THR). We studied 170 consecutive THRs. Sixty-three patients received celecoxib after surgery (200mg twice/daily) for 28 days and 84 did not. HO was more common in non-celecoxib patients than in the celecoxib-group at 3, 6, and 12 months (P =0.005, 0.004 and 0.01...
The purpose of this study was to obtain an amorphous system with minimum unit operations that will prevent recrystallization of amorphous drugs since preparation, during processing (compression) and further storage. Amorphous celecoxib, solid dispersion (SD) of celecoxib with polyvinyl pyrrollidone (PVP) and co-precipitate with PVP and carrageenan (CAR) in different ratios were prepared by the ...
Chronic airway inflammation is a characteristic feature of destructive cigarette smoking (CS)-induced lung disease, particularly in patients with emphysema. Celecoxib, a specific cyclooxygenase-2 (COX-2) inhibitor, is widely used to treat inflammation. However, the exact mechanisms underlying this drug's anti-inflammatory effects have not yet been determined in pulmonary emphysema. Here, we exp...
