Metoprolol tartrate Usage And Synthesis
β1 receptor blocker Metoprolol tartrate is a selective β1-adrenergic receptor blocker,oral absorption is rapid and complete,it is used for the treatment of hypertension, angina pectoris, myocardial infarction, hypertrophic cardiomyopathy, aortic dissection, cardiac arrhythmia, hyperthyroidism, cardiac neurosis and other diseases. In recent years, it is also used for ther treatment of heart failure, which can reduce mortality. In unstable/non-ST-segment elevation myocardial infarction and acute myocardial infarction control guiding principles developed by American Heart Association , effect of metoprolol tartrateare is clearly recognized. In the past, concerns about β-blocker therapy caused hypotension is too large, and for the consideration that there may be racial differences between Asians in β-blocker use and the West, patients with treatment of β-blockers in China is fewer , the use of β-blockers is in lower dose.
Metoprolol tartrate has a weaker membrane stability and it has no intrinsic sympathomimetic activity, and in comparison with similar drugs commonly used in clinical propranolol ,in addition to the advantages of β1-blocker on its pharmacodynamic,it also has its pharmacokinetic kinetics advantages, such as relatively weak first-pass effect compared with propranolol, simple metabolic pathways, most pharmacologically inactive metabolites and the like.
Uses Hypertensive medication.
