Abstract —We evaluated the blood pressure–lowering activity, tolerability, and safety of losartan in 112 hypertensive (sitting diastolic blood pressure, 90 to 115 mm Hg) patients with chronic renal insufficiency including mild renal insufficiency (30 to 60 mL/min per 1.73 m 2 ; n=51), moderate to severe renal insufficiency (10 to 29 mL/min per 1.73 m 2 ; n=33), or hemodialysis (n=28). After a 3-week placebo period, once-daily losatan was administered for 12 weeks. The daily dose of 50 mg was increased to 100 mg after 4 weeks in patients whose sitting diastolic blood pressure remained ≥90 mm Hg or was reduced by 6 mEq/L) requiring discontinuation of losartan occurred in only one (group 2) patient. We conclude that once-daily losartan, given as monotherapy at doses of 50 or 100 mg or in combination with other antihypertensive drugs, was effective in reducing blood pressure in hypertensive patients with chronic renal disease and that losartan regimens were well tolerated in all groups, including those on hemodialysis.
