Losucon M 2/500 SR is a combination medication that contains losartan and hydrochlorothiazide, specifically formulated for the management of hypertension (high blood pressure). Losartan, an angiotensin II receptor blocker (ARB), helps to relax blood vessels, thereby lowering blood pressure, while hydrochlorothiazide, a thiazide diuretic, aids in reducing blood pressure by promoting the excretion of excess sodium and water from the body. The "SR" designation indicates that this formulation is sustained-release, allowing for a gradual release of the active ingredients over an extended period, which can improve patient adherence by minimizing the frequency of dosing. Typically prescribed as part of a comprehensive treatment strategy, Losucon M 2/500 SR aims to effectively control blood pressure and reduce the risk of cardiovascular events.
