Evidence supports high-dose over low-dose atorvastatin in stable coronary heart disease
May 1st 2005Atorvastatin 80 mg/d is associated with better cardiovascular outcomes than atorvastatin 10 mg/d in patients with stable coronary heart disease (CHD), according to John LaRosa, MD, who presented the results of the Treating to New Targets (TNT) study at the ACC Annual Scientific Session 2005.
Secondary stroke prophylaxis: ARB bests calcium antagonist
May 1st 2005The angiotensin receptor blocker (ARB) eprosartan is superior to the calcium antagonist nitrendipine in secondary stroke prophylaxis in patients with hypertension, Hans-Christian Diener, MD, reported at the ASA's International Stroke Conference 2005.
Ramelteon: A novel melatonin receptor agonist for the treatment of insomnia
May 1st 2005Ramelteon (Takeda Pharmaceuticals) is a selective melatonin receptor agonist awaiting FDA approval for the treatment of insomnia. Unlike the currently prescribed hypnotic agents that work by targeting gamma-aminobutyric acid (GABA) receptors, ramelteon offers a novel mechanism of action, specifically targeting the MT1 and MT2 receptors in the brain, which are thought to play a role in regulating sedation and circadian rhythms. Ramelteon is characterized by undergoing extensive first-pass metabolism along with having high oral bioavailability. Results of phase 2 clinical trials have demonstrated that ramelteon-treated patients had significantly shorter sleep onset latencies and longer total sleep times than placebo-treated patients. Furthermore, ramelteon therapy did not appear to impair patient cognition, memory recall, levels of alertness, or ability to concentrate. Data from animal studies suggest that ramelteon is not likely to cause abuse or physical dependence. Unlike the current FDA-approved..
A timely transition to insulin: Identifying type 2 diabetes patients failing oral therapy
April 1st 2005Although oral antidiabetic medications initially may be effective for controlling hyperglycemia, these agents often fail to maintain adequate glycemic control as the disease progresses, and insulin eventually is required in most patients. This review explores strategies for identifying patients with type 2 diabetes who are failing to maintain glycemic control on oral agents and for transitioning these patients to insulin. Based on available data, patients are not reaching recommended glycemic goals due to delays in and reluctance towards intensification of therapy, resulting in an increased risk of complications.
Exenatide: A novel incretin mimetic hormone for the treatment of type 2 diabetes
March 1st 2005A number of clinical approaches are utilized in managing the overlapping aspects of poor glycemic control in patients with type 2 diabetes. Exenatide (Amylin/Lilly), a novel drug in a new medication class known as the incretin mimetic agents, offers a new mechanism to achieve glycemic control.
Prior lack of efficacy with etanercept does not predict lack of efficacy with infliximab
March 1st 2005A study conducted by researchers at the University of Wisconsin, Stanford University, and several rheumatology clinics across the United States found that rheumatoid arthritis (RA) patients who do not receive sufficient benefit with etanercept may experience improved disease control by switching to infliximab.
ACE inhibitors that penetrate the blood-brain barrier may slow Alzheimer's progress
March 1st 2005Researchers have found that angiotensin-converting enzyme (ACE) inhibitors that penetrate the blood-brain barrier (BBB) appear to reduce the incidence of Alzheimer's disease (AD) in elderly patients with hypertension.
ACE inhibitors reduce all-cause mortality in diabetic nephropathy; data unclear for AIIRAs
March 1st 2005A meta-analysis demonstrates that angiotensin converting enzyme (ACE) inhibitors provide a survival benefit in patients with diabetic nephropathy, whereas no such evidence exists for angiotensin II receptor antagonists (AIIRAs).

The use of virtual expert panels: formulary decision-making in the 21st century
March 1st 2005Evidence-based medicine is the driving philosophy for pharmacy and therapeutics (P&T) committee decision-making. When the available evidence is incomplete or unclear, the decision-making process becomes complex. Evaluation of the published literature to make sound decisions regarding appropriate medication use can be a time-consuming process. The use of expert panels or subcommittees may facilitate decision-making; however, this process is often limited by the schedules and time constraints of busy clinicians. This article describes the creation and utilization of a "virtual" panel of experts utilizing anonymous electronic communications to assist the P&T committee at a university-based teaching hospital in making medication use policy. The article includes a detailed description of the P&T committee's experience in the selection of virtual panel members, methods used, advantages, potential pitfalls, and the outcomes of a virtual committee used to evaluate the appropriateness of the off-label use of nesiritide (Natrecor, Scios).
Cilansetron: A novel 5-HT3 receptor antagonist for the treatment of irritable bowel syndrome
February 1st 2005If approved, cilansetron (Calmactin, Solvay Pharmaceuticals) would be the second selective 5-HT3 antagonist introduced for the treatment of irritable bowel syndrome (IBS). Based on 2 main clinical trials, cilansetron 2 mg orally 3 times daily appears to be effective in the relief of IBS-D symptoms (abdominal pain/discomfort) and abnormal bowel habits in both male and female patients. Adverse effects were minor, with constipation being the most commonly reported adverse effect. No information is currently available on cilansetron's potential for drug interactions, need for dose adjustments in renal or hepatic insufficiency, long-term safety, or cost. Cilansetron was granted priority review status by FDA on September 1, 2004, for the treatment of diarrhea-predominant IBS in men and women. Currently marketed agents for the treatment of IBS are only approved for use in female patients.
Update on the treatment of benign prostatic hyperplasia
February 1st 2005Benign prostatic hyperplasia (BPH) is a common chronic disease, with the incidence of BPH increasing with age. Histopathologic features are present in almost half of all men aged >60 years. The disease can have a profoundly negative impact on patients' quality of life, often causing them to limit or avoid basic activities of daily living. Many patients who develop BPH will seek treatment for bothersome lower urinary tract symptoms (LUTS).
