Drug interaction information between Metformin/Empagliflozin and Ranolazine.
Metformin/Empagliflozin and Ranolazine have a documented moderate interaction in FDA labeling.
FDA drug labeling documents a moderate-severity interaction between Metformin/Empagliflozin and Ranolazine. This page displays the available source-record category and label text. The category is not an individual risk estimate or medication-combination direction.
How They Interact
Ranolazine stops the kidneys from filtering metformin out of the blood as quickly as they should. This can lead to high levels of metformin and a higher risk of side effects.
FDA Label Information
Drugs that Reduce Metformin Clearance Clinical Impact Concomitant use of drugs that interfere with common renal tubular transport systems involved in the renal elimination of metformin (e.g., organic cationic transporter-2 [OCT2] / multidrug and toxin extrusion [MATE] inhibitors such as ranolazine, vandetanib, dolutegravir, and cimetidine) could increase systemic exposure to metformin and may increase the risk for lactic acidosis [see Clinical Pharmacology (12.3) ] .
