Telista Trio CL Tablet is a medicine used to treat hypertension (high blood pressure) when a single medication is not effective. It is a combination of three medicines - Telmisartan, Chlorthalidone, and Amlodipine - that work together to lower high blood pressure. Telmisartan is an angiotensin receptor blocker (ARB) that relaxes blood vessels and makes it easier for the heart to pump blood. Chlorthalidone is a diuretic (water pill) that helps to eliminate excess water and salt from the body, reducing fluid buildup and lowering blood pressure. Amlodipine is a calcium channel blocker that relaxes blood vessels and increases blood flow to the heart, reducing the workload on the heart.Telista Trio CL Tablet should be taken with food.
