If you have a heart attack, your doctor may give you metoprolol tartrate (Lopressor). This drug can prevent another heart attack from occurring. However, you should be careful not to confuse it with metoprolol succinate (Toprol-XL). While the two drugs share the same first word and both treat heart-related issues, metoprolol succinate doesn’t prevent or treat a heart attack in people who’ve already had a heart attack. Learn more about the similarities and differences between these two drugs. Metoprolol tartrate and metoprolol succinate contain the same active medication: metoprolol. These salt forms, tartrate and succinate, are approved by the U. Food and Drug Administration (FDA) for different conditions. Both medications belong to a class of drugs called beta-blockers, which work by relaxing your blood vessels and slowing down your heart rate. Metoprolol is a cardioselective β1-adrenergic blocking agent used for acute myocardial infarction (MI), heart failure, angina pectoris and mild to moderate hypertension. It may also be used for supraventricular and tachyarrhythmias and prophylaxis for migraine headaches. Metoprolol is structurally similar to bisoprolol, acebutolol and atenolol in that it has two substituents in the para position of the benzene ring. The β1-selectivity of these agents is thought to be due in part to the large substituents in the para position. At low doses, metoprolol selectively blocks cardiac β1-adrenergic receptors with little activity against β2-adrenergic receptors of the lungs and vascular smooth muscle. Unlike propranolol and pindolol, metoprolol does not exhibit membrane-stabilizing or intrinsic sympathomimetic activity. Membrane-stabilizing effects are only observed at doses much higher than those needed for β-adrenergic blocking activity. Metoprolol possesses a single chiral centre and is administered as a racemic mixture.
