Local anesthetics are a cornerstone of multimodal pain control strategies in the surgical setting as they have a long history of use and an established safety profile. Although effective, their duration of action is relatively short, which usually leads to the use of other agents, such as opioids, for effective postsurgical pain control in most patients. A medical need exists to extend the duration of analgesia with local anesthetics to help reduce the reliance on opioids in the postsurgical setting. ⋯ The most common adverse events with liposomal bupivacaine were nausea, vomiting, and constipation. No adverse effects on the QTc interval or cardiac safety signal have been detected in the clinical trial development program (823 patients) when liposomal bupivacaine was infiltrated into the surgical site. The beneficial effects of liposomal bupivacaine on postsurgical pain management and opioid use, significantly reducing both, are likely to translate into improved clinical and economic outcomes.

Despite numerous pharmacologic and nonpharmacologic treatment strategies, heart failure remains a complex, progressive disorder with significant morbidity and mortality. Angiotensin-converting enzyme (ACE) inhibitors, angiotensin II receptor blockers (ARBs), and β-blockers have been used as routine treatment options for heart failure for the majority of patients with left ventricular systolic dysfunction who tolerate these agents. Mineralocorticoid receptor antagonists (MRAs) have also demonstrated significant benefits in the treatment of heart failure, which include a reduction in sudden cardiac death and ventricular remodeling; however, these agents have not been recommended for most patients with heart failure. ⋯ Based on more recent evidence, it is likely that future recommendations and guidelines will further expand the use of MRAs to patients with mild heart failure as well. These agents have the potential to be recommended nearly as universally as ACE inhibitors and β-blockers because of the potential to reduce mortality and hospital admissions for heart failure. The risk of hyperkalemia should be carefully assessed when using these drugs; nonetheless, new strategies being developed may reduce the occurrence of hyperkalemia as well.

Opioid-related adverse drug events (ORADEs) can have a significant impact on patient recovery after surgery. This review investigates the impact of two ORADEs, respiratory depression and postoperative ileus (POI), on clinical and economic outcomes. Opioid-induced ventilatory impairment is a potentially serious ORADE that can result in apnea and even death. ⋯ Data from a retrospective analysis show that a daily hydromorphone dose of 2 mg/day markedly increases the risk of POI. In addition, although the incidence of POI is reduced in patients who undergo laparoscopic surgery or hand-assisted laparoscopic surgery compared with open surgery, the reduction of POI can potentially be negated by excessive opioid use. Therefore, multimodal, opioid-sparing strategies should be explored and used to reduce severe ORADEs and improve outcomes in the surgical setting.

Randomized Controlled Trial
Effect of health literacy on drug adherence in patients with heart failure.
To assess the effect of health literacy on drug adherence in the context of a pharmacist-based intervention for patients with heart failure. ⋯ In patients with heart failure, those with adequate health literacy have better adherence to cardiovascular drugs than those with inadequate health literacy. The pharmacist intervention improved adherence in patients with adequate and inadequate health literacy. Health literacy may be an important consideration in drug adherence interventions.
