Weltelmi MT 50mg Tablet is a combination of two medicines: Telmisartan and Metoprolol. Telmisartan is an angiotensin receptor blocker (ARB) which works by blocking the hormone angiotensin thereby relaxing blood vessels. Metoprolol is a beta blocker that works specifically on the heart to slow down the heart rate. Together, they allow the blood to flow more smoothly and the heart to pump more efficiently.
