ARBs are a class of drugs that have been clinically proven to halt and even reverse aortic root dilatation in humans. They include valsartan, telmisartan
, and other drugs that end in -sartan. The key is to take a high enough dosage - for most people, this is about the maximum FDA-approved dose. In particularly large people, the required dose may be higher.
