In contrast to irbesartan, losartan was uricosuric and decreased serum uric acid levels. Losartan 50 mg b.i.d. did not produce a greater fall in serum uric acid than losartan once a day. Losartan might be a useful therapeutic tool to control blood pressure and reduce serum uric acid levels in hypertensive patients with hyperuricaemia and gout.

These results show that the differences in angiotensin II receptor blockade observed with the various AT(1) antagonists are explained mainly by differences in dosing. When 160-mg or 320-mg doses were investigated, the effects of valsartan hardly differed from those obtained with recommended doses of irbesartan and candesartan.

These data show that the renal sodium retention developing during LBNP, and thus sympathetic nervous stimulation, is due mainly to an increase in sodium reabsorption by the proximal segments of the nephron. Our results in humans also confirm that, depending on its magnitude, LBNP leads to a step-by-step activation of neurohormonal, renal tubular, and renal hemodynamic responses.

The results show that in hypertensive patients, cuff inflation at the wrist produces a smaller reactive rise in blood pressure. The difference between the arm and the wrist is independent of the patient's level of blood pressure.
