Randomized Controlled Trial
Renal protection of losartan 50 mg in normotensive Chinese patients with nondiabetic chronic kidney disease.
Nondiabetic chronic kidney disease (CKD) is the leading major cause of end-stage renal disease in developing countries including China. Among the 5 stages of CKD, it is critical to retard the progression of stage 3 because renal disorder could accelerate aggravation behind that stage. Data suggest that high dosages of angiotensin receptor blockers (ARBs) could retard the progression of renal disease in hypertensive and/or diabetic patients. Nevertheless, in daily practice of nephrology, quite a number of nondiabetic patients with CKD who are normotensive do not tolerate even moderate dosages of ARBs because of adverse effects such as systemic hypotension, epically for Chinese patients. The aim of this study was to investigate the renoprotective effects of relatively low dosages of ARBs in normotensive Chinese patients with nondiabetic stage 3 CKD. ⋯ For normotensive patients with nondiabetic stage 3 CKD, therapy with a daily dose of losartan, 50 mg, may perform effective renoprotection without changing blood pressure and be generally safe and well tolerated.
