Ranolazine and Empagliflozin have a documented moderate interaction in FDA labeling.
FDA drug labeling documents a moderate-severity interaction between Ranolazine and Empagliflozin. 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 interferes with how the kidneys clear metformin from your system. This can lead to higher levels of metformin in your blood and a higher risk of a dangerous acid buildup.
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) ] .
