Amlodipine benzenesulfonate tablets are first-line antihypertensive drugs belonging to calcium channel blockers, with a wide range of action, suitable for the prevention and treatment of hypertension and unstable angina pectoris, and can be taken for a long time. The drug is metabolized out of the body through the liver and kidneys, it is difficult to say that there is no damage to the kidneys, and amlodipine benzenesulfonate tablets may also appear in the adverse reactions of urinary symptoms such as “frequent urination”, but at present there is no clear evidence that the drug is harmful to the kidneys. Amlodipine besylate tablets are well absorbed by mouth and are not affected by food intake. The drug should be used under the guidance of a physician, and should not be used blindly to avoid further aggravation of the condition.
