The form of the succinic acid salt of metoprolol, a cardio beta-1 adrenergic receptor competition with hypotensive properties and has no intrinsic sympathomimetic. Metoprolol succinate upset beta-1-adrenergic receptors in the myocardium, thus reducing the rate and the heart muscle contraction force is reduced, and thus a reduction in cardiac output. This composition may also renin secretion, with subsequent reduction of the levels of angiotensin II, thus reducing sympathetic activation decreases, including vasoconstriction, aldosterone secretion.
