ABSTRACT
Older adults taking multiple chronic medications experience an increased risk of adverse drug events and other medication-related problems (MRP). Most current literature on medication management involves researcher-driven intervention, yet few studies investigate patients' understanding of MRP in a diverse community setting. This report investigates patients' perception of MRP and patient-centered strategies among a cohort of the older adult group in a historically Black urban community. The study design is qualitative using structured open-ended questions in a multidisciplinary patient-centered focus group. Patients (age 65 years or older) taking seven or more medications were recruited. The group comprises patients, caregivers, pharmacists, health educators, a physician, and a nurse. Recordings of the group discussion are transcribed verbatim and analyzed using thematic content analysis and categorized by codes developed from the social-ecological model. The group reports patient-provider relationships, previous experience, fear of side effects played important roles in medication adherence. There is an unmet need for medication management education and tools to organize complex medication lists from multiple providers. This study provides important insights into MRP experienced by minority older adults and provided researchers with potential strategies for future interventions.
ABSTRACT
PURPOSE: The pharmacology, pharmacokinetics, clinical efficacy, adverse effects, safety, economic issues, dosage, and place in therapy of nebivolol are reviewed. SUMMARY: Nebivolol is a novel, highly selective beta(1)-receptor blocker that causes peripheral vasodilation by increasing the production and release of nitric oxide and decreasing nitric oxide degradation. The nitric oxide-mediated effects of nebivolol lead to decreases in systemic vascular resistance and large artery stiffness and possible reversal of endothelial dysfunction. Clinical studies have shown nebivolol to be at least as effective at lowering blood pressure as other antihypertensive drugs, including other beta-blockers. The most frequent adverse events reported in nebivolol clinical trials were transient headache, dizziness, and tiredness. In a large trial in patients with heart failure, nebivolol was shown to reduce the composite endpoint of mortality and hospitalizations. Nebivolol is highly lipophilic and is rapidly absorbed after oral administration. The nebivolol dose most commonly used in clinical trials for hypertension was 5 mg daily; no significant further decreases in blood pressure were shown with higher doses. The average dose in clinical trials for patients with heart failure was 5-10 mg daily. Dosage adjustments are recommended in elderly patients and patients with severe renal impairment. CONCLUSION: Nebivolol is a unique, highly selective beta-blocker with vasodilatory properties mediated through the nitric oxide pathway; it may be useful in the treatment of uncomplicated mild-to-moderate essential hypertension and in patients with heart failure.
