Optimal blood pressure control (<130/80 mm Hg) in patients with chronic kidney disease (CKD), despite being the main objective of conservative therapy, is rarely achieved in clinical practice. A major area of improvement is the correction of the extracellular volume expansion. This goal can be reached by means of dietary salt restriction (≤Ü100 mEq/d of NaCl). If this intervention fails, hypertension can be treated by thiazide diuretics in patients with mild CKD, whereas loop diuretics at adequate doses are indicated in patients with more advanced CKD. Angiotensin-converting enzyme inhibitors and angiotensin receptor blockers are more effective than other drugs in slowing progression of proteinuric diabetic and nondiabetic CKD. However, the control rates of blood pressure are usually inadequate with antihypertensive therapy including only these drugs; therefore, addition of other classes of antihypertensive drugs is often required.
