Treatment of proteinuria with lercanidipine associated with reninangiotensin axis-blocking drugs
Aim. Most calcium antagonists do not seem to reduce microalbuminuria or proteinuria. We have tried to assess the antiproteinuric effect of a calcium channel blocker, lercanidipine, in patients previously treated with ACE inhibitors or angiotensin receptor blockers.

Summary: | Aim. Most calcium antagonists do not seem to reduce microalbuminuria or proteinuria. We have tried to assess the antiproteinuric effect of a calcium channel blocker, lercanidipine, in patients previously treated with ACE inhibitors or angiotensin receptor blockers. Design and methods. The study included 68 proteinuric (>500 mg/day) patients (age 63,1±12,9 years, 69,1 % males and 30,9 % females). All patients were receiving ACE inhibitors (51,4 %) or angiotensin II receptor blockers (48,6 %) therapy but had higher blood pressure (BP) than recommended for proteinuric patients (<130/80 mm Hg). Patients were clinically evaluated one, three, and six months after starting treatment with lercanidipine (20 mg/day). Samples for urine and blood examination were taken during the examination. When needed, a third drug was added to treatment. Creatinine clearance was measured using 24 h urine collection. Results. BP significantly decreased from 152±15/86±11 mm Hg to 135±12/77±10 mm Hg at six months of follow-up (p<0,001). After six months of treatment, the percentage of normalized patients (BP <130/80 mm Hg) was 42,5 %, and the proportion of patients whose BP was below 140/90 mm Hg was 58,8 %. Plasmatic creatinine did not change nor did creatinine clearance. Plasmatic cholesterol also decreased from 210±48 to 192±34 mg/dL (p<0,001), as did plasma triglycerides (from 151±77 to 134±72 mg/dL, p=0,022). Basal proteinuria was 1,63±1,34 g/day; it was significantly (p<0,001) reduced by 23 % at the first month, 37 % at three months, and 33 % at the last visit.Conclusion. Lercanidipine at 20 mg dose, associated with renin-angiotensin axis-blocking drugs, showed a high antihypertensive and antiproteinuric effect. This antiproteinuric effect seems to be dose-dependent as compared with previous reports and proportionally higher than blood pressure reduction. |
