Randomized Controlled Trial Comparative Study Clinical Trial
Efficacy and tolerability profile of etoricoxib in patients with osteoarthritis: A randomized, double-blind, placebo and active-comparator controlled 12-week efficacy trial.
To evaluate the efficacy of 12 weeks of treatment with etoricoxib, a selective COX-2 inhibitor, in patients with osteoarthritis (OA) of the knee or hip. ⋯ Etoricoxib showed rapid and durable treatment effects in patients with OA of the knee or hip. Etoricoxib was generally well tolerated.

Neuroprotective agents inhibit reactions in the brain ischaemic injury cascade which lead to neuronal death. Gamma-aminobutyric acid (GABA) is a naturally occurring inhibitory neurotransmitter that increases chloride influx into the neuron and counteracts the toxic effects of glutamate. ⋯ Promising results in animal models resulted in clinical trials conducted in humans. However, large randomized placebo controlled trials in Europe, Canada and North America did not show the superiority of clomethiazole over placebo that was seen in animal models.

Antipsychotic drugs have been available for more than 40 years. The invention of neuroleptics changed the overall treatment of schizophrenia dramatically. Nevertheless, the discussion on the importance and role of antipsychotic therapy still goes on. ⋯ The atypical antipsychotic agents have improved the quality of therapy and can also improve and support other aspects of treatment. When used with other treatment strategies, atypical antipsychotic agents could improve the overall outcome of this usually chronic disease. It is now necessary to implement these strategies as effectively as possible.

Prevalence of obesity in the United Kingdom has tripled in the last 20 years and this is driving an epidemic of type 2 diabetes. Indeed, today the vast majority of patients with type 2 diabetes are overweight or obese. Effective weight management leading to modest weight loss to the order of 5-10% of body weight can lead to significant clinically meaningful benefits provided it can be maintained. ⋯ An integrated approach to weight management in the diabetic patient is recommended which helps to promote lifestyle modification for all patients. Drug therapy may be appropriate for many obese patients who do not reach target weight loss with lifestyle modification alone. Surgery should be reserved for those wfth BMI >40 only after failed medical therapy.

Non-selective non-steroidal anti-inflammatory drugs (NSAIDs) inhibit both cyclo-oxygenase (COX) isoenzymes, i.e. COX-1 and COX-2. Rofecoxib, an agent that selectively inhibits COX-2, has been shown to provide equivalent anti-inflammatory and analgesic efficacy to comparator non-selective NSAIDs in osteoarthritis (OA) and other pain models with a significant improvement in gastrointestinal (GI) safety and tolerability. Based on renal physiology studies, it was predicted that rofecoxib would have renovascular effects similar to those observed with non-selective NSAIDs--specifically edema, blood pressure elevation, attenuation of the effects of ACE inhibitors, and (in rare circumstances), acute renal failure might be manifest in a small percentage of patients. ⋯ In the rofecoxib phase IIb/III OA database, the renal safety profile for rofecoxib, a selective inhibitor of COX-2, was generally similar to that of the comparator, non-selective NSAIDs which were studied.
