A beta blocker first strategy appears to be as safe and effective as an ACE inhibitor first strategy for the treatment of older patients with heart failure, and may confer an early survival advantage.
The ACE inhibitor perindopril significantly reduced left ventricular remodeling in a well-treated population of older patients with acute myocardial infarction (MI) and preserved ejection fraction, said Roberto Ferrari, MD, PhD, lead investigator of the Perindopril Remodeling in Elderly with Acute Myocardial Infarction (PREAMI).
FDA approved a new influenza vaccine (Fluarix, GlaxoSmith-Kline) for adults aged 18 years and older.

FDA's Pulmonary-Allergy Drugs Advisory Committee voted unanimously that the long-acting beta 2-agonists salmeterol (Serevent and Advair, GlaxoSmithKline) and formoterol (Foradil, Novartis) should remain on the market despite concern over reports of asthma-related deaths associated with the use of salmeterol.
Muraglitazar (Bristol-Myers Squibb/Merck) is a new agent under investigation for the treatment of patients with type 2 diabetes. It belongs to a novel class of drugs that target the peroxisome proliferator-activated receptors, both alpha and gamma subtypes. Available clinical data describe improvements in glycemic parameters similar to available thiazolidinediones. In addition to improvements in blood glucose and hemoglobin A (HbA 1c), muraglitazar treatment is associated with a substantial reduction in triglycerides (TGs), an increase in HDL-C, and a modest decrease in LDL-C levels. Safety data are limited, but in available abstracts, there are reports of moderately elevated rates of edema, weight gain, and hypoglycemia with muraglitazar compared with placebo or pioglitazone. When used in combination with metformin or glyburide, chronic heart failure events have been reported with muraglitazar. If approved, muraglitazar will provide a convenient alternative for the treatment of type 2 diabetes. (Formulary. 2005;40:285–293.)
Revised labeling was issued for tadalafil (Cialis, Lilly ICOS), vardenafil (Levitra, Bayer/GlaxoSmithKline/Schering-Plough), and sildenafil (Viagra, Pfizer) to reflect a small number of post-marketing reports of sudden vision loss, attributed to non-arteritic ischemic optic neuropathy (NAION).
One year of bisphosphonate therapy maintains the gains in bone mineral density (BMD) experienced after 1 year of full-length parathyroid hormone (1–84) in postmenopausal women at risk of osteoporotic fracture. The findings were published in the New England Journal of Medicine (2005;353:555–565).
Cost-effectiveness of 4 empiric antimicrobial regimens in patients with community-acquired pneumonia
This study compares the cost-effectiveness of the 4 most common empiric antimicrobial regimens used for the treatment of adults with community-acquired pneumonia (CAP) at a community health system during a 6-month period. Associations between initial antimicrobials and total hospital costs were determined. Cost-effectiveness ratios were determined by dividing the total hospital costs by the percent survival. A total of 415 patients met criteria for the Pneumonia Severity Index (PSI) risk class IV or V. Costs (adjusted for inflation) were as follows (median, 25th and 75th percentile): total hospital costs ($5,078 [$3,218–$8,144]), pharmacy costs ($753 [$455–$1,357]), and antibiotic costs ($139 [$82–$229]). The most favorable cost-effectiveness ratio was observed for patients who received levofloxacin monotherapy ($4,635 per life saved), followed by ceftriaxone plus a macrolide ($5,278), ceftriaxone monotherapy ($5,368), and ceftriaxone plus levofloxacin ($6,317).
Desmopressin tablets 0.1 and 0.2 mg (equiv to DDAVP tablets).
Pioglitazone acts primarily by decreasing insulin resistance, while metformin improves glucose tolerance in patients with type 2 diabetes, lowering both basal and postprandial plasma glucose.
Valsartan (Diovan, Novartis) received an expanded indication for reducing cardiovascular mortality in patients who are at high risk due to left ventricular failure or dysfunction after myocardial infarction.
This NSAID is believed to exert its therapeutic effect through inhibition of prostaglandin synthesis, primarily via inhibition of cyclooxygenase-2 (COX-2). Celecoxib was approved on July 29, 2005, for the relief of the signs and symptoms of ankylosing spondylitis (AS).
Phase 3 clinical trial results have demonstrated that the dual alpha/gamma peroxisome proliferator-activated receptor (PPAR) agonist muraglitazar achieves significant beneficial lipid effects compared with pioglitazone, and the agent also provides long-term glycemic control in type 2 diabetics. The results were reported during the American Diabetes Association (ADA) 65th Annual Meeting in San Diego, Calif.

Levothyroxine, a critical medication for millions of Americans, has had a long and turbulent history. In the face of tougher FDA regulations and especially its reclassification as a "new drug" in 1997, manufacturers have struggled to carve out their niche in an expansive market. The principal concern of physicians, patients, endocrinologists, manufacturers, and FDA is levothyroxine's relative bioequivalence. Even after FDA classified several products as bioequivalent, a single brand name product still holds most of the market share, despite the fact that it is more costly. Current issues surrounding levothyroxine include: controversy about research, the number and types of recalls, the lack of a single reference-listed drug for comparison, and conflicting claims about the bioequivalence of various formulations. (Formulary. 2005;40:258–271.)
After months of delay, the Senate confirmed Lester M. Crawford, DVM, PhD, in July as the official head of FDA. Despite efforts by some Senators to hold up the vote pending resolution of some FDA policies, most legislators agreed with Republican and Democratic leaders that the agency would be better off with a permanent chief than without.
