The answer is no. Ezetimibe and simvastatin are the active ingredients in Vytorin, but neither is a generic version of Vytorin. What can be confusing is that, oftentimes, the active ingredient of any drug is referred to as the "generic name." The generic name is different from a generic version of a medicine. In order for there to be a generic version of a medicine, the original medicine must have gone off-patent and another company besides the original manufacturer must make the product.
