Losucon M 1/500 SR is a combination medication that contains losartan and hydrochlorothiazide, designed for the management of hypertension (high blood pressure). Losartan, an angiotensin II receptor blocker (ARB), works by relaxing blood vessels to lower blood pressure, while hydrochlorothiazide is a thiazide diuretic that helps reduce blood pressure by promoting the excretion of excess sodium and water from the body. The "SR" designation indicates that this formulation is a sustained-release version, allowing for a gradual release of the active ingredients over time, which can enhance patient compliance by reducing the frequency of dosing. Typically prescribed as part of a comprehensive treatment plan, Losucon M 1/500 SR aims to effectively control blood pressure and reduce the risk of cardiovascular complications.
