Ranolazine (Ranexa) Pharmacology Podcast

Ranolazine is primarily used for chronic angina management. I discuss pharmacology, drug interactions, adverse effects, and more in this podcast episode. Ranolazine is well known to have drug interactions. CYP3A4 is of major importance but there are other subtle drug interactions that are important. QTc prolongation has been reported with ranolazine so it is important to recognize risk factors and other medications that may contribute to this concern. Enzyme inducers like carbamazepine, phenytoin, and St. John's wort are all associated with reducing the concentrations of ranolazine.
