If approved, tipranavir (Boehringer Ingelheim) will be the ninth protease inhibitor (PI) available and the first nonpeptidic PI available in the United States. Designed by structure-based analysis, tipranavir is more flexible at the binding site, allowing for a potent and durable antiretroviral response. The tipranavir (TPV) and ritonavir (RTV) PI regimen (TPV/r) studied in clinical trials had a moderate pill burden, requiring 4 pills to be taken twice daily (2 RTV 100 mg and 2 TPV 250 mg).
Although 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.
This novel echinocandin antifungal exerts its antibiotic activity by inhibiting the synthesis of 1,3-?-D-glucan, an essential component of fungal cell walls.

Ziprasidone (Geodon, Pfizer) and risperidone (Risperdal, Janssen) are equally efficacious in the treatment of patients with acute exacerbation of schizophrenia and schizoaffective disorder, with ziprasidone demonstrating a lower movement disorder burden and less effect on prolactin concentrations and weight than risperidone.
A 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.
Concurrent use of oral erythromycin and strong inhibitors of CYP3A should be avoided, according to research published in The New England Journal of Medicine.
Despite unanimity in the belief that the COX-2 selective nonsteroidal anti-inflammatory drugs (NSAIDs) significantly increase cardiovascular risk, FDA's Arthritis and Drug Safety and Risk Management Advisory Committees have advised FDA that the risk/benefit profile of the previously approved COX-2 inhibitors support the marketing of these agents in the United States.
President George W. Bush recently nominated Lester M. Crawford, DVM, PhD, to take the permanent role of FDA commissioner after serving as acting or deputy administrator since February 2002.
A 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.

Researchers 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.
A 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).

Evidence-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).

If 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.
Benign 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).
A community-based study confirmed that alpha antagonist monotherapy for the treatment of hypertension is associated with an increased risk of congestive heart failure (CHF) compared to thiazide diuretic monotherapy. Study authors stated that this increased risk is only partly explained by differences in blood pressure control. The increased risk was observed in women but not in men in this prospective cohort study.
The American Heart Association (AHA) Scientific Sessions comprise the largest meeting of its kind held in the cardiovascular field, with several thousand presentations given each year. The recently concluded 2004 AHA Scientific Sessions, which took place in New Orleans, included presentations of trials that evaluated potential therapeutic compounds, as well as widely used and accepted compounds in new dosages or combinations, for the treatment of cardiovascular disorders. The compilation of clinical news that follows focuses on the cardiovascular pharmacotherapy trials of greatest interest to formulary decision-makers, including: CREATE, PEACE, A-HeFT, PROTECT, CLEAR Platelets, DIPOM, GEMINI, SHIELD, and RIO-NA.
