Public Citizen requests bans on Arava, Meridia

From Consumer Advocy Groups:Public Citizen urges ban on Arava. . . According to Public Citizen, 130 cases of severe liver toxicity-including 56 hospitalizations and 12 deaths-have been reported to the FDA since the 1998 introduction of rheumatoid arthritis agent leflunomide (Arava). This equates to six times the number of cases of fatal liver toxicity seen with methotrexate, although 5.5 times more prescriptions for methotrexate were filled over the 3-year comparative period. Public Citizen also says that leflunomide has been associated with 12 cases of Stevens-Johnson syndrome (compared with none reported with methotrexate) and more reports of lymphoma and hypertension.

Milrinone for acute exacerbations of CHF: Routine use not recommended

Ratherthan shortening the hospital stay and improving clinical outcomes, a 48-hour infusion of milrinone was associated with increased early treatment failure-particularly due to the development of arrhythmias and hypotension-in patients hospitalized with acute exacerbations of chronic heart failure (CHF).

Longer is better for thromboembolism prophylaxis after cancer surgery

Enoxaparin (Lovenox) is typically used during hospitalization after orthopedic or abdominal surgery. Recent studies of its use after orthopedic surgery have shown that extending administration of the low-molecular-weight heparin after hospital discharge significantly reduces the frequency of deep-vein thrombosis (DVT). A new study confirms this is also the case for abdominal surgery for cancer, which carries a high risk of this complication.

Popular antidepression herb doesn't stand up in clinical trial-but an SSRI doesn't either.

Neither extracts of Hypericum perforatum (St. John's Wort) nor sertraline (Zoloft) tested in patients with major depressive disorder performed better than placebo in reducing patients' scores on a standard assessment of depression severity.

No advantage to omapatrilat over enalapril in heart failure . . .

The investigational vasopeptidase inhibitor omapatrilat is as effective as enalapril in preventing major adverse cardiac outcomes in patients with moderate to severe heart failure, but failed to show superiority, said Milton Packer, MD.

ACC Pearls in Brief

LIPS: Statin reduces cardiac event risk by 22% in first PCI procedureAzithromax ineffective for reducing recurrent CV events

Primary strategy in atrial fibrillation: Rate control is as acceptableas rhythm control

Cardiac events: Losartan beats beta blocker in patients with diabetes,HTN, & LVH

Therapy starting with the angiotensin receptor blocker (ARB) losartansignificantly reduced the risk of cardiovascular outcomes and new-onsetdiabetes compared with a beta blocker in older high-risk hypertensive patients,said Björn Dahlöf, MD. The improved outcomes with losartan occurredeven after adjusting for small differences in blood pressure reduction betweenthe two study drugs.

Outcomes in ACS: GP IIb/IIIa inhibitor plus LMWH superior to GPs plus unfractionated heparin

Atlanta-The low-molecular-weight heparin enoxaparin improves outcomes compared with currently recommended therapy in patients with non-ST-segment elevation acute coronary syndromes (ACS) who are being treated with a glycoprotein (GP) IIb/IIIa inhibitor, said Shaun Goodman, MD.

Lercanidipine: A long-acting dihydropyridine calcium channel blocker for treatment of hypertension

Lercanidipine is currently under FDA review for the management of hypertension. In comparative clinical trials, lercanidipine has shown antihypertensive efficacy comparable to that of slow-release nifedipine, amlodipine, nitrendipine, verapamil, captopril, and atenolol. Its side effect profile is similar or superior to these agents. This Focus article reviews those trials as well as lercanidipine?s pharmacologic properties and addresses the agent?s potential role in patients with comorbid conditions.

Part one of a two-part series: Beyond depression: Evaluation of newer indications and off-label uses for SSRIs (PDF)

Although selective serotonin reuptake inhibitors (SSRIs) are prescribed most often for depression disorders, they are increasingly being used to treat a variety of other conditions. In this article, the authors assess the evidence on anxiety disorders—generalized anxiety disorder, obsessive-compulsive disorder, panic disorder, posttraumatic stress disorder, and social phobia. For each condition, they present the rationale for SSRI use, the degree of supportive clinical trial evidence, indication-specific dosing and safety considerations, and their recommendations for the preferred and alternative SSRIs.
