Effect of long-term carvedilol therapy on renal function in essential hypertension.
We assessed the long-term effects of carvedilol on renal function in 10 patients with mild-to-moderate essential hypertension. After a 2- to 4-week placebo run-in period, all patients received 5 mg carvedilol once daily. If the effect was insufficient, the dosage was successively increased to 10 or 20 mg once daily. The mean +/- SEM duration of treatment was 17.3 +/- 1.0 weeks, and the final mean daily dosage was 13.5 +/- 2.2 mg/day. With treatment, systolic and diastolic blood pressures decreased significantly from 159.7 +/- 1.3 to 140.5 +/- 3.2 mm Hg (p less than 0.001) and from 98.3 +/- 1.0 to 88.2 +/- 2.7 mm Hg (p less than 0.001), respectively. Carvedilol did not cause significant changes in glomerular filtration rate, effective renal plasma flow, blood urea nitrogen, or serum creatinine. Renal vascular resistance decreased significantly from 12.7 +/- 1.4 to 11.2 +/- 1.2 dyne.s.cm-5/1.48 m2 x 10(3) (p less than 0.05). Thus, long-term carvedilol therapy was effective in reducing blood pressure in essential hypertension without causing impairment of renal function.
