Drugs to improve vascular microcirculation include vasodilator drugs, lipid-lowering drugs or antiplatelet drugs. Common vasodilators include calcium ion blockers, nitrate drugs, etc. Calcium ion blockers include verapamil and nifedipine. Nitrate drugs include nitroglycerin, isosorbide nitrate, etc., all of which can play a role in improving the microcirculation of cardiovascular and peripheral blood vessels. Common lipid-lowering drugs are mainly statin lipid-lowering drugs, such as atorvastatin, resuvastatin, etc., which can effectively control cholesterol and triglyceride, and at the same time, due to the reduction of blood viscosity, the microcirculation can also be well improved. Common antiplatelet drugs include aspirin, clopidogrel, etc., which can effectively control the progress of vascular plaque, and at the same time for microcirculation can play a role in controlling the formation of small thrombi. The use of medication should be under the guidance of a professional doctor, not unauthorized use of medication.
