Vasodilators are given to treat local hypertension (high blood pressure, in the kidneys). These have the advantage that they are diuretic and can thus compensate for the reduced ability of the kidneys to concentrate. These drugs also help to reduce blood pressure.
Also, a kidney diet is prescribed (both dry and canned food). The purpose of an adapted diet is to reduce the urea and creatinine in the bloodstream. Therefore, the concentration of protein, phosphorus, and sodium in the diet must be changed.
Finally, a dietary supplement such as Lpakitin can ensure the absorption of toxins (including creatinine and urea) and thus reduce the strain on the kidneys.
