The purpose of the Metadon 25 AM Tablet is to regulate elevated blood pressure and heart rate. Two medications are combined in Metadon 25 AM Tablet PR. Although they do it in different ways, both medications reduce blood pressure. When combined, they lower heart rate, relax blood vessels, and facilitate the heart's ability to pump blood throughout the body. As a result, blood pressure drops. Controlling blood pressure also lowers the risk of kidney issues, heart attacks, and strokes. For this medication to work, it must be taken as directed on a regular basis.
