Review Meta Analysis
Combination therapy with inhaled long-acting beta2-agonists and inhaled corticosteroids: a paradigm shift in asthma management.
Long-acting inhaled beta2-agonists and inhaled corticosteroids are classes of drugs with different mechanisms of action that are commonly used to provide effective long-term control of persistent asthma. Scientific and clinical data support the complementary mechanisms of action of the inhaled corticosteroids and the long-acting beta2-agonists in achieving a superior level of asthma control. In addition, evidence supports significant reductions in exacerbations and effective control of airway inflammation with an inhaled corticosteroid and a long-acting beta2-agonist versus higher dosages of inhaled corticosteroids or combinations of other therapeutic agents with an inhaled corticosteroid. Finally, there are distinct economic advantages to combining an inhaled corticosteroid and a long-acting beta2-agonist in the treatment of asthma relative to other treatment regimens.

Comparative Study
Pharmacist impact on posttraumatic seizure prophylaxis in patients with head injury.
Phenytoin is the most commonly administered antiepileptic agent for the prevention of early (< or = 7 days) posttraumatic seizures. Use of the agent, however, requires strict monitoring due to its narrow target range and nonlinear pharmacokinetics. The impact of a clinical pharmacist participating in the care of patients with head injury on posttraumatic seizure prophylaxis with regard to phenytoin dosing and monitoring, cost avoidance, and patient outcome, was measured retrospectively. ⋯ Seizures occurred in 4.7% (BP) and 1.5% (AP) of patients. A cost savings of approximately $28,000 was observed for the AP group. A clinical pharmacist reduced the use of posttraumatic seizure prophylaxis and associated costs without jeopardizing patient outcomes.

To assess the pharmacokinetics of levofloxacin during continuous venovenous hemodiafiltration (CVVHDF) and continuous venovenous hemofiltration (CVVH). ⋯ Marked extracorporeal elimination of levofloxacin occurs, requiring a dosage adjustment that can be calculated from the characteristics of CVVH and CVVHDF.

The direct relationships and associations among clinical pharmacy services, pharmacist staffing, and medication errors in United States hospitals were evaluated. A database was constructed from the 1992 National Clinical Pharmacy Services database. Both simple and multiple regression analyses were employed to determine relationships and associations. ⋯ Specific increases or decreases in yearly medication errors associated with these clinical pharmacy services in the 1081 study hospitals were drug-use evaluation (21,372 more medication errors), drug information services (26,738 fewer medication errors), adverse drug reaction management (44,803 fewer medication errors), drug protocol management (90,019 fewer medication errors), medical round participation (42,859 fewer medication errors), and medication admission histories (17,638 fewer medication errors). Overall, clinical pharmacy services and hospital pharmacy staffing variables were associated with medication error rates. The results of this study should help hospitals reduce the number of medication errors that occur each year.
