<s>[INST] What is the best medicine for kidney disease? [/INST] Currently, the most effective medications for kidney disease are ACE inhibitors and ARBs, which may effectively repair the GFR and treat CKD. They are also widely used to treat high blood pressure, as they help relax the blood vessels. However, these drugs can produce side effects such as excessive potassium in the blood; and may lead to heart failure if the dosage is not controlled. None of these drugs can treat severe CKD from stages 3-5.
