Taking lipid-lowering drugs has no effect on lowering blood pressure. Lipid-lowering drugs and antihypertensive drugs have different mechanisms of action. At present, common clinical lipid-lowering drugs such as statins, mainly through competition to inhibit the key enzyme of cholesterol synthesis to reduce cholesterol, ezetimibe is mainly inhibit cholesterol absorption; Beta drugs such as fenofibrate, mainly through the inhibition of the generation of very low-density lipoproteins and triglycerides, and to increase the decomposition of its metabolism in order to reduce blood lipids. Antihypertensive drugs such as calcium channel blocker nifedipine, mainly inhibit calcium channels to diastole; β-blockers such as metoprolol to reduce heart rate, cardiac output and blood pressure; diuretics such as hydrochlorothiazide to reduce blood volume; ACEI such as captopril to reduce peripheral vascular resistance, inhibit aldosterone secretion to reduce water-sodium retention, vasodilatation and so on. In summary, antihypertensive drugs and lipid-lowering drugs do not have the same mechanism of action, taking lipid-lowering drugs will not appear to lower blood pressure. Therefore, it is recommended to consult a doctor in time to standardize the diagnosis and treatment.
