Non-elderly patients with overactive bladder have significant comorbidities
August 1st 2005A study was conducted to evaluate the clinical and economic burden of overactive bladder (OAB) among patients <60 years of age in a managed care population, especially with regard to the prevalence of related comorbidities and associated annual medical costs.
Dual peroxisome proliferator-activated receptor agonist demonstrates significant lipid benefits
August 1st 2005Phase 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.
The levothyroxine spectrum: Bioequivalence and cost considerations
August 1st 2005Levothyroxine, 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.

Crawford seeks to restore confidence in FDA approval process
August 1st 2005After 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.
Tigecycline: A novel glycylcycline antiobiotic
August 1st 2005Highly resistant strains of both gram-positive and gram-negative bacteria are becoming commonplace in both the inpatient and outpatient setting. Recently developed antimicrobials have targeted resistant gram-positive pathogens, but the problem of resistant gram-negative pathogens remains. Tigecycline (Tygacil, Wyeth) is an injectable antimicrobial and the first in a new class of agents (the glycylcyclines) that possesses activity against key gram-positive and gram-negative bacterial pathogens. Tigecycline overcomes common tetracycline resistance mechanisms and has shown in vitro and in vivo activity against multidrug-resistant organisms. Tigecycline treatment produced clinical and microbiologic outcomes similar to standard comparator agents in patients with complicated skin and skin structure infections and complicated intra-abdominal infections and was approved for these indications in June 2005. The most common adverse events associated with tigecycline's administration during clinical trials were..
NSAID utilization patterns following market withdrawal of rofecoxib
July 1st 2005Cyclooxygenase-2 (COX-2)-selective nonsteroidal anti-inflammatory drugs (NSAIDs) have been widely prescribed for patients with arthritis and other conditions because of their lower risk for gastrointestinal adverse events compared with nonselective NSAIDs 1,2
Dapoxetine: A novel, fast-acting serotonin reuptake inhibitor
July 1st 2005Dapoxetine (Alza/Ortho-McNeil) is a novel oral medication undergoing FDA review for premature ejaculation, one of the most common disorders of sexual dysfunction in men. Dapoxetine is a fast-acting inhibitor of the serotonin reuptake transporter. It has a short half-life and is structurally related to the antidepressant fluoxetine, allowing for on-demand dosing.
Cost analysis of combination vs single dosage lipid-lowering
July 1st 2005A study was conducted to determine the cost and patient adher- ence rates of lipid-lowering therapy with an extended-release niacin and lovastatin (ERNL) combination agent versus a separate extended-release niacin and statin (ERN-S) combination or statin monotherapy.
Trends in utilization of alternative analgesics after rofecoxib withdrawal
July 1st 2005The objective of this study was to track the utilization of anti-inflammatory drugs among patients with active rofecoxib prescriptions at the time of market withdrawal through retrospective analysis of pharmacy records and to assess the need for COX-2 inhibitor therapy due to gastrointestinal risk factors.
Alvimopan: A peripherally selective opioid mu receptor antagonist
June 1st 2005Post-operative ileus causes significant patient morbidity and is a major contributor to patient discomfort and increased length of hospitalization post-operatively. Alvimopan (Entereg, Adolor/GlaxoSmithKline), a peripherally selective opioid mu receptor antagonist with gastrointestinal (GI) tract-specific activity, is undergoing FDA review for the treatment of post-operative ileus.
New board to improve internal oversight, consumer communication of drug safety issues
May 1st 2005The new independent Drug Safety Oversight Board (DSB) within CDER will employ a two-pronged approach to create "a new culture of openness, improved oversight, and enhanced independence," according to FDA officials.
California HMOs required to cover all 'medically necessary' drugs
May 1st 2005New regulations proposed by the California state Department of Managed Health Care (DMHC) that are expected to be implemented by the end of this year would require HMOs in California to cover all medically necessary prescription drugs, even if they are excluded from a plan's formulary.

Warfarin underperforms in preventing stroke in the real world in patients with chronic AF
May 1st 2005Analyses of 3 retrospective databases found that warfarin is much less effective at preventing strokes in the real world in patients with chronic atrial fibrillation (AF) than it is in clinical trials. The retrospective data were reported at the ASA's International Stroke Conference 2005.
