OBJECTIVE To compare the efficacy and safety of two different doses of celecoxib and diclofenac in the treatment of Norwegian patients with ankylosing spondylitis. METHODS In this 12-week, double-blind, non-inferiority trial patients were randomized to 200 mg once daily (qd) celecoxib, 400 mg qd celecoxib, or 50 mg three times daily (tid) diclofenac. The primary objective compared patients' a...

Pharmacosomes are amphiphilic lipid vesicular systems that have shown their potential in improving the bioavailability of poorly water soluble as well as poorly lipophilic drugs. Diclofenac is a poorly water soluble drug and also causes gastrointestinal toxicity. To improve the water solublity of diclofenac, its pharmacosomes (phospholipid complex) have been prepared and evaluated for physicoch...

Aim: Ibuprofen400mg and Diclofenac Sodium 50mg marketed today inhibit Cox-1 and Cox-2 and have selectivity for Cox-1. Ibuprofen 400mg is an established analgesic in the management of acute dental pain. Diclofenac Sodium 50mg is also used in the management of acute pain, but there are very few studies comparing its analgesic efficacy with Ibuprofen. Materials and Method: A double blind randomize...

BACKGROUND Combinations of non-steroidal anti-inflammatory drugs with opioids are frequently used to reduce opioid doses required in the clinical management of acute pain. The present study was designed to evaluate the possible antinociceptive interaction between morphine and diclofenac at peripheral level in male rats. METHODS Drugs were chosen based on their efficacy in the treatment of thi...

In this research, we investigated the cytotoxic mechanisms of one of the widely used pharmaceuticals that are regularly associated with the adverse effects on the liver, sometimes leading to acute liver failure, diclofenac. Diclofenac liver cytotoxicity was associated with reactive oxygen species (ROS) formation and lipid peroxidation which were inhibited by antioxidants and ROS scavengers, fer...

BACKGROUND The aim was to study the role of rectal diclofenac in prevention of post-endoscopic retrograde cholangiopancreatography (ERCP) pancreatitis and its impact on severity of post-ERCP pancreatitis. METHODS We conducted a single-center, prospective, open-labeled, randomized trial for evaluating the use of rectal diclofenac in prevention of post-ERCP pancreatitis in high-risk patients. W...

BACKGROUND Treatment of osteoarthritis with oral NSAID therapy provides pain relief but carries a substantial risk of adverse effects. Topical NSAID therapy offers an alternative to oral treatment, with the potential for a reduced risk of side effects. The objective of this trial was to assess the safety and efficacy of a topical diclofenac solution in relieving the symptoms of primary osteoart...
