Reduce diastolic blood pressure should be combined with the causes of increased diastolic blood pressure for medication, as follows: 1, the heart shoots blood to the aorta, if the peripheral vascular resistance increases, the amount of blood flowing from the aorta to the periphery will be reduced, causing increased diastolic blood pressure; application of calcium antagonists, such as amlodipine and nifedipine controlled-release tablets, helps to reduce peripheral vascular resistance and promote blood flow from the aorta to the periphery, thus reducing The application of heart rate slowing drugs, such as metoprolol extended-release tablets, bisoprolol, carvedilol, etc., helps to slow down the heart rate and shorten the systolic period, thus reducing diastolic blood pressure. However, in the vast majority of cases, systolic blood pressure is elevated together with diastolic blood pressure.
