    (Elsevier, 2016-05) Leonard, Charles E.; Han, Xu; Bilker, Warren B.; Flory, James H.; Brensinger, Colleen M.; Flockhart, David A.; Gagne, Joshua J.; Cardillo, Serena; Hennessy, Sean; Department of Medicine, IU School of Medicine
    We conducted high-dimensional propensity score-adjusted cohort studies to examine whether thiazolidinedione use with a statin or fibrate was associated with an increased risk of severe hypoglycemia. We found that concomitant therapy with a thiazolidinedione+fibrate was associated with a generally delayed increased risk of severe hypoglycemia.

    Severe hypoglycemia in users of sulfonylurea antidiabetic agents and antihyperlipidemics
    (Wiley, 2016-05) Leonard, Charles E.; Bilker, Warren B.; Brensinger, Colleen M.; Han, Xu; Flory, James H.; Flockhart, David A.; Gagne, Joshua J.; Cardillo, Serena; Hennessy, Sean; Department of Medicine, IU School of Medicine
    Drug-drug interactions causing severe hypoglycemia due to antidiabetic drugs is a major clinical and public health problem. We assessed whether sulfonylurea use with a statin or fibrate was associated with severe hypoglycemia. We conducted cohort studies of users of glyburide, glipizide, and glimepiride plus a statin or fibrate within a Medicaid population. The outcome was a validated, diagnosis-based algorithm for severe hypoglycemia. Among 592,872 persons newly exposed to a sulfonylurea+antihyperlipidemic, the incidence of severe hypoglycemia was 5.8/100 person-years. Adjusted hazard ratios (HRs) for sulfonylurea+statins were consistent with no association. Most overall HRs for sulfonylurea+fibrate were elevated, with sulfonylurea-specific adjusted HRs as large as 1.50 (95% confidence interval (CI): 1.24-1.81) for glyburide+gemfibrozil, 1.37 (95% CI: 1.11-1.69) for glipizide+gemfibrozil, and 1.63 (95% CI: 1.29-2.06) for glimepiride+fenofibrate. Concomitant therapy with a sulfonylurea and fibrate is associated with an often delayed increased rate of severe hypoglycemia.
