There are more types of antihypertensive drugs in the class of Lol, which are more commonly used in clinical practice, and there is no saying which one is better, different patients have different physical symptoms and need different medications. Metoprolol includes metoprolol tartrate tablets and metoprolol succinate extended-release tablets. 1. Metoprolol tartrate tablets: for hypertension, angina pectoris, etc. Beta-blockers may have adverse effects on the fetus and the newborn, especially bradycardia, and therefore should not be used during pregnancy or labor. The use of the drug should be under the supervision of an experienced physician. 2. Metoprolol succinate extended-release tablets: for those with hypertension, angina pectoris, and abnormal left ventricular systolic function. Adverse reactions are usually dose-related. Initial hypotension is not necessarily an inability to tolerate the dose of the product for long-term treatment, and the dose can only be increased after the condition has stabilized. Other considerations include the possible need for increased monitoring of renal function. It is contraindicated in individuals who are hypersensitive to any of the ingredients or to other beta-blockers. There are a variety of medications for lowering blood pressure in the Lol class, and if treatment needs to be interrupted when using the above medications for a long period of time, the dosage must be gradually reduced, and the choice of which medication to use should be made on the basis of a doctor’s recommendation.
