RESUMEN
Medication nonadherence, a major problem in cardiovascular disease (CVD), contributes yearly to approximately 125,000 preventable deaths, which is partly attributable to only about one-half of CVD patients consistently taking prescribed life-saving medications. Current interest has focused on how labeling and education influence adherence. This paper summarizes the scope of CVD nonadherence, describes key U.S. Food and Drug Administration initiatives, and identifies potential targets for improvement. We describe key adherence factors, methods, and technological applications for simplifying regimens and enhancing adherence, and 4 areas where additional collaborative research and implementation involving the regulatory system and clinical community could substantially reduce nonadherence: 1) identifying monitoring methods; 2) improving the evidence base to better understand adherence; 3) developing patient/health provider team-based engagement strategies; and 4) alleviating health disparities. Alignment of U.S. Food and Drug Administration approaches to dissemination of information about appropriate use with clinical practice could improve adherence, and thereby reduce CVD death and disability.

Blacks are two to three times as likely as whites to die of preventable heart disease and stroke. Declines in mortality from heart disease have not eliminated racial disparities. Control and effective treatment of hypertension, a leading cause of cardiovascular disease, among blacks is less than in whites and remains a challenge. One of the driving forces behind this racial/ethnic disparity is medication nonadherence whose cause is embedded in social determinants. Eight practical approaches to addressing medication adherence with the potential to attenuate disparities were identified and include: (1) patient engagement strategies, (2) consumer-directed health care, (3) patient portals, (4) smart apps and text messages, (5) digital pillboxes, (6) pharmacist-led engagement, (7) cardiac rehabilitation, and (8) cognitive-based behavior. However, while data suggest that these strategies may improve medication adherence, the effect on ameliorating racial/ethnic disparities is not certain. This review describes the relationship between disparities and medication adherence, which likely plays a role in persistent disparities in cardiovascular morbidity and mortality.

OBJECTIVE: Metformin was approved by the Food and Drug Administration in 1995 subject to the conduct of a randomized trial to evaluate the risk of lactic acidosis or other serious adverse events (SAEs) with this agent, under usual care conditions. RESEARCH DESIGN AND METHODS: The Comparative Outcomes Study of Metformin Intervention versus Conventional (COSMIC) Approach Study was a randomized, open-label, active-comparator, parallel-group, 1-year trial in type 2 diabetic patients suboptimally controlled on diet or sulfonylurea. Patients received metformin (n = 7,227) or other usual care treatments (n = 1,505). The primary end point was the incidence of SAEs, death, and hospitalization. RESULTS: SAEs occurred in 10.3% (95% CI 9.6-11.1%) of the metformin group and in 11.0% (9.5-12.7%) of the usual care group (P = 0.431). Lactic acidosis did not occur. All-cause mortality (1.1% [0.9-1.4%] vs. 1.3% [0.8-2.0%], P = 0.596) and hospitalization (9.4% [8.8-10.1%] vs. 10.4% [8.9-12.1%], P = 0.229) were similar between groups. CONCLUSIONS: The incidence of SAEs was similar between groups. Lactic acidosis was not observed. Metformin may be safely prescribed for type 2 diabetes if contraindications and warnings are respected. This study demonstrates the utility of large, simple trials for risk evaluation of treatments for common diseases.
