Celecoxib is a nonsteroidal anti-inflammatory drug (selective cyclooxygenase-2 inhibitor) that is widely used. The efficacy and safety of celecoxib for treatment of acute postoperative pain were evaluated in Japanese patients. The objective was to assess whether celecoxib showed superiority over placebo treatment and non-inferiority versus etodolac (another selective cyclooxygenase-2 inhibitor)...

  Objective: Non-steroidal anti-inflammatory drugs (NSAIDs) are the most commonly prescribed pain control medications following periodontal surgery. This study aimed to compare the efficacy of three drug regimens namely celecoxib, celecoxib + caffeine and ibuprofen for pain relief following crown lengthening surgery.   Methods: This randomized, double blind clinical trial was performed on 45 pa...

Recently, many studies have shown that celecoxib induces apoptosis in various cancer cells by different mechanisms depending on the cell type. This study examined the effect of the selective COX-2 inhibitor celecoxib on cisplatin and TNF-α cytotoxicity and studied the role of mitochondria in the induction of apoptosis in the human cervical carcinoma SiHa cells. Apoptosis was detected by flow cy...

Celecoxib, a selective cyclooxygenase-2 inhibitor, is potentially useful for the treatment of colonic diseases such as colorectal cancer and colitis. However, the cardiovascular toxicity of celecoxib limits its routine use in the clinic. Generally, colon-specific delivery of a drug both increases the therapeutic availability in the large intestine and decreases the systemic absorption of the dr...

BACKGROUND AND OBJECTIVES The prevalence of arthritis, which is often treated with celecoxib, is high in patients with coronary artery disease. Furthermore, celecoxib has been reported to reduce restenosis after coronary stenting by inhibiting expression of the proto-oncogene Akt. A concern is that celecoxib increases thrombogenicity by inhibiting the synthesis of prostacyclin in endothelial ce...

PURPOSE Celecoxib, a highly selective cyclooxygenase-2 inhibitor, regulates apoptosis of several types of human cancer cells. The purpose of this study was to investigate whether celecoxib in combination with paclitaxel modulates apoptosis of ovarian cancer cells, and to identify the signal pathway by which celecoxib mediates apoptosis. MATERIALS AND METHODS OVCAR-3 cells were exposed to pacl...

The major sulfated product of 17alpha-ethynylestradiol (EE) after incubations with 3'-phosphoadenosine-5'-phosphosulfate and recombinant human sulfotransferase 2A1 (SULT2A1), or liver cytosol, is the 3-O-sulfate of EE. However, when celecoxib is also present in the incubation, sulfation is switched (in a concentration-dependent manner) from the 3-O-position to the 17beta-O-position of ethynyles...

Cancer cells express survivin that facilitates tumorigenesis. Celecoxib has been shown to reduce human colorectal cancers. However, the role and regulation of survivin by celecoxib in colorectal carcinoma cells remain unclear. Treatment with 40-80 muM celecoxib for 24 h induced cytotoxicity and proliferation inhibition via a concentration-dependent manner in RKO colorectal carcinoma cells. Cele...

OBJECTIVE The purpose of this study was to compare the efficacy and tolerability of a celecoxib 200 mg QD regimen with a 100 mg BID regimen in patients with osteoarthritis (OA) of the knee. METHODS Patients enrolled in this prospective, double-blind, placebo-controlled, parallel-group, multicenter study were randomly assigned to receive celecoxib 100 mg BID, celecoxib 200 mg QD, or placebo fo...
