Beta-blockers, CCBs, ACEIs and ARBs, and diuretics are all high blood pressure medications and do not harm the kidneys, among which ACEIs and ARBs can protect the kidneys. 1. β-blocking drugs: such as Betalucil, propranolol, etc., by blocking β-receptors, the heart’s contractility decreases, conduction decreases, and the heart rate slows down, so as to lower the blood pressure. 2. CCBs, such as isobarbital, diltiazem, etc., by blocking calcium channels, myocardial contractility decreases, blood vessels dilate, and blood pressure decreases. 3. ACEI and ARB: the former, such as captopril and enalapril, antagonize the RAAS system by blocking angiotensin-converting enzyme and play a role in lowering blood pressure; the latter, such as valsartan and chlorosartan, antagonize the RAAS system by blocking the angiotensin II receptor and play a role in lowering blood pressure. 4. Diuretics: including furosemide, hydrochlorothiazide, spironolactone, etc., which reduce blood pressure through diuresis.
