Rotigotine: The first transdermal nonergot-derived dopamine agonist for the treatment of Parkinson disease

Parkinson disease (PD) is a chronic, progressive neurodegenerative disorder affecting approximately 1% of people aged >60 years. Levodopa has long been the cornerstone of PD treatment, but many patients receiving long-term levodopa therapy experience dyskinesia and motor fluctuations. Dopamine agonists act directly on dopamine receptors and are associated with a lower incidence of dyskinesias. There are 2 subclasses of dopamine agonists: ergot-derived and nonergot-derived. The use of ergot-derived dopamine agonists has declined in recent years due to the agents' association with valvular heart disease. Nonergot-derived dopamine agonists such as ropinirole and pramipexole are used more widely in the treatment of PD. Rotigotine is a nonergot-derived dopamine agonist that was approved by FDA on May 9, 2007, for the treatment of early-stage idiopathic PD. Rotigotine is the first approved nonergot-derived dopamine agonist that is delivered continuously through a transdermal silicone-based patch that is replaced..

A summary of agents in late-stage development for the treatment of Alzheimer's disease (November 2007).

Adding prostaglandin blocker to niacin ER reduces flushing without compromising effects on lipids

An investigational drug that combines niacin extended-release (ER) and laropiprant, a prostaglandin D2 receptor antagonist, reduces the flushing that often leads to niacin ER discontinuation while preserving the agent's beneficial effects on lipids, according to lead author Darbie Maccubbin, PhD, Merck Research Laboratories, Rahway, New Jersey, et al. The results of this research were presented at the European Society of Cardiology Congress 2007 in Vienna, Austria, September 1 to 5, 2007. The drug is pending FDA approval.

Unfavorable risk:benefit ratio with antiplatelet plus anticoagulant therapy for peripheral arterial disease

In a randomized, controlled, open-label trial in patients with peripheral arterial disease (PAD), it was demonstrated that antiplatelet therapy plus an oral anticoagulant was no better at preventing major cardiovascular complications than antiplatelet therapy alone. The combination therapy was also associated with a significant increase in life-threatening bleeding complications compared with monotherapy.

MERLIN: Ranolazine associated with antiarrhythmic effect

In a prespecified secondary analysis of the Metabolic Efficiency with Ranolazine for Less Ischemia in Non-ST Elevation Acute Coronary Syndromes (MERLIN)-TIMI 36 trial, ranolazine was associated with a reduction in the number of episodes of ventricular tachycardia and supraventricular tachycardia. The results of the analysis were presented at the European Society of Cardiology Congress 2007 in Vienna, Austria.

GRACE and SCAAR add to the debate about stents

Questions about the safety of drug-eluting stents (DES) versus bare metal stents (BMS) persisted after 2 studies presented at the European Society of Cardiology (ESC) Congress 2007 in Vienna, Austria, demonstrated varying effects of DES and BMS on long-term mortality.

Statins associated with reduction in 10-year risk of cataracts

In the Blue Mountains Eye Study published in the American Journal of Ophthalmology, statin use was demonstrated to be protective against the development of cataracts, reducing a patient's risk by nearly half.

Use of SSRIs in early pregnancy not associated with increased risk of most birth defects

In 2 large, case-control studies published in the New England Journal of Medicine (NEJM), researchers demonstrated that, overall, a woman's use of a selective serotonin-reuptake inhibitor (SSRI) in early pregnancy was not associated with significantly increased risks of congenital heart defects or most other types of birth defects.

Focus on 2007: A year of novel pharmacologic agents in review; arformoterol, pramipexole, CERA, sitaxsentan, bifeprunox, vernakalant, telavancin, maraviroc, and rotigotine

Throughout 2007, Formulary's "Focus on" articles have examined 9 newly approved or investigational drugs of interest to pharmacy and therapeutics committee members. Because many readers have said that they frequently reference this column when making formulary decisions for their hospitals, health systems, or managed care organizations, the editors have compiled this review of these agents, along with updates on the regulatory status of each. Of the 9 agents reviewed in 2007, 4 have received final FDA approval; the remaining 5 agents have not yet been approved by FDA.

Maraviroc: The first CCR5 antagonist for the treatment of HIV

Maraviroc is the first CCR5 antagonist approved for the treatment of HIV-1 infection. The use of maraviroc is associated with significant decreases in HIV viral load and increases in CD4 counts in antiretroviral treatment-experienced patients with CCR5-tropic virus when used as an add-on to optimized antiretroviral treatment. In clinical trials, patients with dual- or mixed-tropic virus (which can infect cells using CXCR4 and/or CCR5 receptors) who were treated with maraviroc demonstrated no difference in HIV viral load compared with patients who received placebo. A recent study compared maraviroc plus lamivudine/zidovudine with efavirenz plus lamivudine/zidovudine; maraviroc did not demonstrate noninferiority when undetectable virus was defined as <50 copies/mL; however, maraviroc did meet noninferiority criteria when undetectable virus was defined as <400 copies/mL. Maraviroc is not recommended for patients with CXCR4-tropic, dual-tropic, or mixed-tropic virus; for antiretroviral-naive patients; or for..

Older agents for type 2 diabetes equal or superior to newer agents for glycemic control, lipid levels, body weight

An extensive systematic review published in the Annals of Internal Medicine demonstrated that older oral drugs for type 2 diabetes are just as, if not more, effective than newer agents for gylcemic control, lipid control, and other intermediate end points.

The impact of angiotensin II receptor blocker potency on the clinical outcomes of stroke, acute myocardial infarction, or death

Angiotensin II receptor blockers (ARBs) have been demonstrated to reduce morbidity and/or mortality in patients with chronic heart failure (CHF), acute myocardial infarction (AMI), type 2 diabetes, and hypertension. Although as a class ARBs share a common mechanism of action, potency among the agents varies. Higher-potency ARBs (candesartan, irbesartan, olmesartan, and telmisartan) may demonstrate improved 24-hour blood pressure control, suggesting that these agents may have superior clinical event reduction potential versus lower-potency agents (eprosartan, losartan, and valsartan). We conducted a meta-analysis of randomized, controlled trials that evaluated the effect of ARBs on clinical outcomes. A systematic literature search of MEDLINE from 1966 through December 2006 was conducted using specific search terms. Studies that met the following criteria were included: randomized; not angiotensin-converting enzyme (ACE) inhibitor-controlled; incorporation of monotherapy with ARBs in 1 or more of the treatment..
