An overview of the pathophysiologyand treatment of secondary peritonitis
February 1st 2003Intraabdominal infection was first thoroughly described by Hippocrates. Centuries later, despite advances in surgical and supportive therapies, this disease state continues to be associated with significant morbidity and mortality. This article reviews the literature on intraabdominal infections. It describes the pathophysiology, classification, and etiology of intraabdominal infections, focusing primarily on secondary peritonitis. The bacteriology of the gastrointestinal tract in both the normal and infected host is reviewed. Treatment options, including newly approved antimicrobial agents and agents under clinical investigation, are reviewed.
Incorporating an ethical template into pharmacy benefit decision-making (PDF)
January 1st 2003J Russell Teagarden, MA, RPh, vice president of clinical practices and therapeutics at Medco Health Solutions in Franklin Lakes, NJ, explains how using an ?ethical template? for pharmacy benefit decisions can make those decisions consistent and fair, reducing patient displeasure, conflict, and litigation.
A comparison of the newer treatment options for ADHD (PDF)
January 1st 2003Psychostimulant drugs have consistently demonstrated efficacy in the treatment of attention-deficit/hyperactivity disorder (ADHD). Innovative technology has fueled the development of novel release mechanisms and isolation of active enantiomer components with the hopes of enhancing the duration of action and improving the safety and effectiveness. As a result, several new stimulant agents have recently been added to the arsenal of ADHD treatment options. Formulary selection is complicated by the high costs and small but distinct differences among these agents. The five newest FDA-approved stimulant agents for the treatment of ADHD are detailed, and a brief summary of future treatment options, including a recently approved nonstimulant agent, is provided.
Incorporating an ethical template into pharmacy benefit decision-making
January 1st 2003If asked, could you present the underlying rationale for your pharmacy benefit coverage decisions? When considered from the consumer or employee perspective, why should they consider the payors or providers of their drug benefit legitimate decision-makers in limiting their healthcare policies?
Duloxetine: An antidepressant that inhibits both norepinephrine and serotonin uptake
January 1st 2003Duloxetine is a reuptake inhibitor at serotonergic and noradrenergic neurons and appears to have low affinity for other neurotransmitter systems. In three published clinical trials in patients with MDD, duloxetine was well tolerated and more effective than placebo. Further study is needed to compare its efficacy with that of other antidepressants, to prospectively assess time to onset of antidepressant effect, and to clarify effects on somatic symptoms and potential adverse cardiovascular and sexual effects. Duloxetine is also under investigation for the treatment of stress urinary incontinence in women (trade name to be determined, comarketed by Lilly and Boehringer Ingelheim). Preliminary information suggests that duloxetine therapy reduces the number of incontinence episodes. Duloxetine has been deemed ?approvable? for the treatment of MDD and will be comarketed under the trade name Cymbalta by Eli Lilly and Company and Quintiles.
Migraine therapy: balancing efficacy and safety with quality of life and cost (PDF)
December 1st 2002Successful management of migraine attacks and their symptoms leads to economic benefits such as decreased reliance on healthcare resources, decreased employee absenteeism, and increased productivity. Appropriate treatment includes prophylaxis with lifestyle changes and drug therapy, and acute therapy with drugs. Over-the-counter analgesics can be effective acute therapy for mild migraine; for moderate to severe attacks, the 5HT1B/1D agonists, or triptans, offer significant efficacy and cost-effectiveness.
Ezetimibe: a novel cholesterol absorption inhibitor (PDF)
December 1st 2002Ezetimibe (Zetia), approved in late October, represents the first new class of cholesterol-lowering drugs in 15 years. Ezetimibe, an intestinal cholesterol absorption inhibitor, has a unique mechanism of action, distinct from those of statins and bile acid sequestrants. When used as monotherapy, ezetimibe lowers low-density lipoprotein cholesterol (LDL-C) levels up to 18.5%. Coadministration of ezetimibe with statin therapy reduces LDL-C levels up to an additional 22%. The article reviews ezetimibe?s chemistry, pharmacology, pharmacokinetics, and clinical trial results.
From ICAAC: Microbial resistance, preventing herpes transmission at conference forefront
November 1st 2002Microbial resistance is a concern in treating urinary tract infection (UTI) and bacteremia. But analysis of data from more than 200 US hospitals in the Surveillance Network Database-USA from 1999 to 2001 demonstrated bloodstream and urinary tract isolates with the potential to cause urosepsis to be very susceptible in vitro to broad-spectrum b-lactams and aminoglycosides. The study results were reported at the 42nd Annual Interscience Conference on Antimicrobial Agents and Chemotherapy (ICAAC) in San Diego, CA.
From the Stanley Conference: Options expand for bipolar disorder
November 1st 2002Studies presented at the Third European Stanley Foundation Conference on Bipolar Disorder in September in Freiburg, Germany, show two newer antipsychotics are each more effective than standard therapy for preventing mania relapse or reducing symptoms.
From the MTIRS: Anticonvulsant reduces migraine headache frequency
November 1st 2002A phase III study presented at the 14th annual meeting of the Migraine Trust International Research Symposium (MTIRS) in September in London showed that topiramate (Topamax) significantly reduced migraine frequency at doses as low as 100 mg/d. The onset of efficacy was observed as early as the first month of treatment. Topiramate is already approved in the United States and worldwide as an
Aripiprazole: First of a new class of antipsychotics (PDF)
November 1st 2002Aripiprazole is an investigational atypical antipsychotic that received an approvable status from FDA in September 2002 for the treatment of schizophrenia. The decision on approval could be made as early as the end of this year. Aripiprazole offers a unique mechanism of action as a dopamine system stabilizer. Aripiprazole has been found to be effective in both short-term (4?6 wk) and long-term (26?52 wk) treatment trials. It appears to produce less hyperprolactinemia, weight gain, and extrapyramidal symptoms than other antipsychotics.
HMG CoA reductase inhibitor-induced muscle toxicity: risks, monitoring, and management (PDF)
November 1st 2002Although the commonly used HMG CoA reductase inhibitors (statins) are well tolerated and relatively safe, muscle toxicity and rhabdomyolysis can occur with administration and can be severe. This risk is higher with more bioavailable and lipophilic statins. This article summarizes what is known about the etiology of statin-associated muscle toxicity, the risks for each statin, and the current recommendations for monitoring and management.
Charging drug representatives for physician visits: Three leadersexplain why and how
November 1st 2002Formulary has identified three organizations that recently begancharging pharmaceutical representatives a fee to meet withphysicians. Two of the organizations-Queen City Physicians and thePolyclinic-are physician group practices based in Cincinnati, OH,and Seattle, WA, respectively.
Xendos study: Orlistat plus diet prevents, delays diabetes onset in obese patients
October 1st 2002Orlistat (Xenical) in combination with diet and lifestyle changes significantly prevents obese patients from developing type 2 diabetes, say researchers involved in this 4-year study presented at the 9th International Congress on Obesity, Sao Paulo, Brazil. They add that this is the first time a weight loss drug has been shown to prevent or delay the onset of type 2 diabetes in an at-risk population.
Rethinking approaches to reducing medication errors: An examination of 10 core processes (PDF)
September 1st 2002Although many organizations have implemented well-intentioned medication error reduction strategies, the authors of this article argue that most approaches don?t address the underlying foundation upon which many errors occur. In this article, they present 10 core process improvements?from ?genericizing? all drug names throughout the hospital/health system to purchasing all single-dose packaging?that they believe could have a significant impact on patient safety if implemented.
