ABSTRACT
OBJECTIVE: To describe the pharmacologic and pharmacokinetic properties of a new beta-adrenergic blocker, nebivolol, and review the literature evaluating its efficacy in the treatment of hypertension and heart failure. DATA SOURCES: Articles were identified through searches of MEDLINE (1996-May 2006) and International Pharmaceutical Abstracts (1970-May 2006), using the key word nebivolol. Additional references were selected from the bibliographies of the articles cited. Searches were not limited by language, time, or human subject. STUDY SELECTION AND DATA EXTRACTION: Preclinical studies evaluating the pharmacologic and pharmacokinetic properties of nebivolol in humans were selected for review. Randomized, controlled, blinded clinical trials assessing the efficacy of nebivolol for the treatment of hypertension and heart failure were also included. DATA SYNTHESIS: Preclinical data have established nebivolol as a third-generation beta-adrenergic blocker, as it possesses vasodilatory properties that contribute to its hemodynamic effects beyond those achieved at beta-adrenergic receptors. Short-term, randomized, controlled clinical trials have shown nebivolol to be as effective as other antihypertensive therapies at lowering blood pressure. One long-term trial showed a significant reduction in death and hospital admissions for cardiovascular causes when nebivolol was compared with placebo in patients with heart failure (31.1% vs 65.3%; HR 0.86; 95% CI 0.74 to 0.99). CONCLUSIONS: Nebivolol is a novel beta-adrenergic blocker that possesses unique pharmacologic properties, compared with other agents in its class. Nebivolol appears to be as effective as other antihypertensive agents at lowering blood pressure and possesses benefits for patients with heart failure. Additional studies are needed to address the long-term benefits of nebivolol for hypertension, to compare nebivolol with other beta-adrenergic blockers for heart failure, and to investigate the clinical relevance of nitric oxide-mediated vasodilation.

OBJECTIVE: To assess a model to screen minority, elderly, and at-risk individuals for diabetes, hypertension, and dyslipidemia in pharmacy and non-health care settings. DESIGN: Multicenter, prospective, observational trial. SETTING: 26 pharmacies and 4 non-health care settings. PARTICIPANTS: 888 individuals with one or more of the following risk factors: first-degree relative with diabetes, age 55 years or older, obesity, previous diagnosis of hypertension, or a previous diagnosis of dyslipidemia. INTERVENTION: Measurement of plasma glucose, total cholesterol, high-density lipoprotein cholesterol (HDL-C), and blood pressure; risk assessment using a risk factor tool; referral of participants with abnormalities to physicians. MAIN OUTCOME MEASURES: Adherence with follow-up, physician recommendations, and new diagnoses of diabetes, hypertension, and dyslipidemia. RESULTS: Pharmacists screened 888 participants in pharmacies and non-health care settings; 794 scored at least 10 on the risk factor tool and received further screenings. Of these, 81% were referred for follow-up for at least one abnormality: 15% glucose, 68% blood pressure, 66% total cholesterol, and 26% HDL-C. For those referred, the mean (+/- SD) fasting plasma glucose concentration was 179 +/- 87 mg/dL, and the random glucose concentration was 234 +/- 90 mg/dL. Of participants completing follow-up, 16% received one or more new diagnoses as follows: diabetes, 8; hypertension, 9; and dyslipidemia, 29. Therapy changed for 42% of participants. Participants who were elderly, of African American and Hispanic race/ethnicity, or those with elevated cholesterol values were at significantly greater risk for elevated glucose levels. Screenings in community pharmacy settings had improved follow-up rates with physicians compared with screenings conducted in non-health care settings. CONCLUSION: Pharmacists identified individuals with elevated glucose, cholesterol, and blood pressure values through community-based screenings. Pharmacists also identified individuals who could benefit from further control of previously diagnosed hypertension and hyperlipidemia.

Current practice guidelines provide recommendations for the secondary prevention of coronary heart disease. Following the publication of clinical trials in recent years, this review will highlight some controversial issues: the role of angiotensin and aldosterone antagonists after acute myocardial infarction; the effects of angiotensin-converting enzyme inhibitors in patients with stable coronary heart disease and preserved left ventricular ejection fraction; high-intensity lowering of low-density lipoprotein cholesterol; use of 3-hydroxy-3-methyl-glutaryl coenzyme A reductase inhibitors in the elderly; and the targeting of high-density lipoprotein cholesterol with niacin.
