Levamlodipine maleate is a dihydropyridine calcium channel antagonist, which can inhibit the transmembrane entry of calcium ions into vascular smooth muscle cells and cardiomyocytes to reduce vascular tone, and is mainly used in the treatment of hypertension, chronic stable angina pectoris, and angina pectoris variabilis. Usually, it is not affected by food intake, so it can be taken together with meals, and it can be rapidly absorbed through the gastrointestinal tract, so that the peak concentration of the drug can be reached in about 6 hours, and it can play the role of lowering blood pressure.
