Lopid (gemfibrozil) tablets
Detailed View: Safety Labeling Changes Approved By FDA Center for Drug Evaluation and Research (CDER) -- July 2009 and September 2010
Repaglinide: In healthy volunteers, co-administration with gemfibrozil (600 mg twice daily for 3 days) resulted in an 8.1-fold (range 5.5- to 15.0- fold) higher repaglinide AUC and a 28.6-fold (range 18.5- to 80.1-fold) higher repaglinide plasma concentration 7hours after the dose. In the same study, gemfibrozil (600 mg twice daily for 3 days itraconazole (200 mg in the morning and 100 mg in the evening at Day 1, then 100 mg twice daily at Day 2-3) resulted in a 19.4- (range 12.9- to 24.7-fold) higher repaglinide AUC and a 70.4-fold (range 42.9- to 119.2-fold) higher repaglinide plasma concentration 7 hours after thedose. In addition, gemfibrozil alone or gemfibrozil + itraconazole prolonged the hypoglycemic effects of repaglinide. Co-administration of gemfibrozil and repaglinide increases the risk of severe hypoglycemia and is contraindicated
- Bile Acid-Binding Resins: Gemfibrozil AUC was reduced by 30% when gemfibrozil was given (600 mg) simultaneously with resin-granule drugs such as colestipol (5 g). Administration of the drugs two hours or more apart is recommended because gemfibrozil exposure was not significantly affected when it was administered two hours apart from colestipol
- Combination therapy of gemfibrozil with repaglinide (due to the risk for severe hypoglycemia)
- Repaglinide: In healthy volunteers, co-administration with gemfibrozil increased the plasma concentration of repaglinide and prolonged its hypoglycemic effects. Coadministration of gemfibrozil and repaglinide increases the risk for severe hypoglycemia and is contraindicated.
