Moxonidine belongs to the group of medicines called Antihypertensive used in the management of high blood pressure. High blood pressure is a medical condition in which the blood exerts high pressure against the walls of the arteries (blood vessels). This increases the heart's workload, and if it continues for a long time, the heart and arteries may not function properly. It can damage the kidney, brain and arteries of the heart. However, lowering blood pressure may reduce the risk of stroke and heart attacks.
