Isradipine capsules 2.5 and 5 mg (equiv to Dynacirc capsules)

The serine protease inhibitor aprotinin (Trasylol, Bayer) may increase the risk of renal failure, myocardial infarction, heart failure, stroke, and encephalopathy among patients undergoing coronary artery bypass graft (CABG) surgery, according to an observational study in the New England Journal of Medicine (NEJM).

By increasing intestinal fluid secretion, lubiprostone increases motility in the intestine, thereby increasing the passage of stool and alleviating symptoms associated with constipation. Lubiprostone was approved on January 31, 2006, for the treatment of chronic idiopathic constipation (CIC) in adults.

The anti-anginal and anti-ischemic properties of ranolazine are not dependent on reductions in heart rate or blood pressure. Ranolazine was approved on January 27, 2006, for the treatment of chronic angina. Because ranolazine prolongs the QT interval, it should be reserved for patients who have not achieved an adequate response with other anti-anginal drugs.

The Medicare Prescription Drug Plan, which began January 1, 2006, makes the federal government the largest purchaser of pharmaceuticals in the United States, and probably in the world. It is projected that the Centers for Medicare and Medicaid Services (CMS) will spend more than $1 trillion on medications over the next decade, a volume that will influence the pharmaceutical market more broadly and generate new initiatives to encourage utilization of more cost-effective treatments.

Although experience tells us that formulary conversion programs are commonplace, they are discussed fairly infrequently in the literature. A recent MEDLINE search did not identify any conversion programs similar to a human growth hormone (HGH) program implemented at HIP Health Plan of New York (HIP-NY).

In an attempt to improve patient outcomes and control costs, a guide to empiric antimicrobial therapy, including a urinary tract infection (UTI) algorithm, was distributed to hospital physicians at an academic medical center. A retrospective study was conducted to assess the impact of the guide on physician prescribing of empiric antimicrobial therapy for UTIs. Prior to the implementation of the guide, 45% (n=55) of patients with UTIs were treated consistently with the algorithm. Although not statistically significant, consistency increased to 51% (n=45) after implementation of the guide. The initial publication of a guide to empiric antimicrobial therapy did not significantly influence physician prescribing patterns regarding UTIs. Educational sessions at the time of implementation along with reinforcement of the guidelines may further impact prescribing habits and influence algorithm compliance.

New inhalable insulin formulation approved

Kinase inhibitor approved for GIST and advanced renal cell carcinoma

Hydromorphone tablets 2, 4, and 8 mg (equiv to Dilaudid tablets)

Patients who have switched statins should receive special care as they are substantially less likely to be compliant and remain on the treatment long enough to obtain its full benefits, researchers reported in the American Journal of Managed Care.

Objective: Pharmacy-managed medication assistance programs (MAP) have the potential to recoup losses incurred by the pharmacy department, but whether this offsets the personnel cost of the program has not been well-established. The purpose of this study was to conduct a cost-benefit analysis of the pharmacy-managed MAP at an urban teaching clinic at Hartford Hospital in Hartford, Conn.

The number-one health policy issue for the new year is to find ways to keep healthcare costs under control. An aging population and more costly medical technology could increase current spending trends. These developments could have an impact on efforts to reduce the number of uninsured people in the United States and could prompt initiatives to make consumers more aware of treatment costs and options.

Sitaxsentan, a highly selective endothelin-A (ET-A) receptor antagonist undergoing FDA review as an alternative to bosentan for pulmonary arterial hypertension (PAH) treatment, demonstrated improved efficacy over bosentan in a recent study.

The presence of antibodies to heparin is an independent risk factor for potentially serious complications following cardiac surgery, even in patients who do not develop heparin-induced thrombocytopenia (HIT), said David Kress, MD, at the 71st international scientific assembly of the American College of Chest Physicians in Montreal, Quebec, Canada.

A pivotal phase 3 trial of a fully human monoclonal antibody, denosumab, that prevents bone destruction is under way and includes 7,800 postmenopausal, osteoporotic women aged 60 to 90 years. The primary endpoint is new vertebral fractures versus placebo and secondary end points are safety and tolerability of the new agent. Phase 2 clinical trials have demonstrated that denosumab is superior to aldendronate in preserving bone mineral density (BMD), reported researchers during the American College of Rheumatology Annual Scientific Meeting in San Diego, Calif.

Beta blockers, touted for 3 decades as first-line drugs in the treatment of hypertension, are less than optimum in comparison to other antihypertensive drugs and raise the risk of stroke, according to a meta-analysis published online by The Lancet.

Patients who have switched statins should receive special care as they are substantially less likely to be compliant and remain on the treatment long enough to obtain its full benefits, researchers reported in the American Journal of Managed Care.

Utilizing statin therapy, researchers have provided further evidence that absolute reductions in LDL-C reduce the incidence of coronary heart disease (CHD) and other major vascular events.

The calcium sensitizer levosimendan was associated with an improvement in the clinical course of patients compared with placebo when used for the treatment of acute decompensated heart failure (ADHF), but the drug failed to reduce 6-month mortality when compared with dobutamine in a similar set of patients.

Drugs that reduce brachial blood pressure similarly can have different effects on central blood pressure. This finding may explain differences in clinical end points between antihypertensive drugs that lower blood pressure similarly, said Bryan Williams, MD, lead investigator of the Conduit Artery Function Evaluation (CAF?) trial, a substudy of the Anglo-Scandinavian Cardiac Outcomes Trial (ASCOT).

In a trial comparing high-dose atorvastatin with moderate-dose simvastatin in patients with stable coronary heart disease (CHD), the aggressive LDL-lowering strategy offered no significant advantage over the less aggressive strategy in reducing the number of coronary events, said Terje R. Pedersen, MD.

A nicotinic acetylcholine receptor partial agonist is an effective smoking cessation aid, said Serena Tonstad, MD, PhD, professor of nutrition at the Ulleval University Hospital, Oslo, Norway.

The anti-anginal agent ranolazine, in phase 3 clinical trials, reduced anginal frequency in patients experiencing 3 or more anginal attacks per week despite daily treatment with amlodipine 10 mg/d said Peter Stone, MD, lead investigator of the Evaluation of Ranolazine in Chronic Angina (ERICA) trial.

An exploratory analysis of PROactive (Prospective Pioglitazone Clinical Trial In Macrovascular Events Study) demonstrated a significant reduction in the risk of a second coronary event in patients with type 2 diabetes who took pioglitazone.

Oral anticoagulant therapy proved superior to the combination of clopidogrel and aspirin in preventing adverse vascular outcomes in patients with atrial fibrillation (AF). This outcome was observed in a large, multicenter trial at the 2005 AHA meeting in Dallas, comparing warfarin therapy with combination antiplatelet therapy in patients with AF.
